internal/proto: move location of cue/cue.proto
This makes cuelang.org/cue/encoding/protobuf (git)
the import path and cue/cue.proto the canonical
import name.
Add google files for import, even though the types
are mapped, for better validation.

+// `Any` contains an arbitrary serialized protocol buffer message along with a
+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form
+// of utility functions or additional generated methods of the Any type.
+//
+// Example 1: Pack and unpack a message in C++.
+//
+// Foo foo = ...;
+// Any any;
+// any.PackFrom(foo);
+// ...
+// if (any.UnpackTo(&foo)) {
+// ...
+// }
+//
+// Example 2: Pack and unpack a message in Java.
+//
+// Foo foo = ...;
+// Any any = Any.pack(foo);
+// ...
+// if (any.is(Foo.class)) {
+// foo = any.unpack(Foo.class);
+// }
+//
+// Example 3: Pack and unpack a message in Python.
+//
+// foo = Foo(...)
+// any = Any()
+// any.Pack(foo)
+// ...
+// if any.Is(Foo.DESCRIPTOR):
+// any.Unpack(foo)
+// ...
+//
+// Example 4: Pack and unpack a message in Go
+//
+// foo := &pb.Foo{...}
+// any, err := ptypes.MarshalAny(foo)
+// ...
+// foo := &pb.Foo{}
+// if err := ptypes.UnmarshalAny(any, foo); err != nil {
+// ...
+// }
+//
+// The pack methods provided by protobuf library will by default use
+// 'type.googleapis.com/full.type.name' as the type URL and the unpack
+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+// package google.profile;
+// message Person {
+// string first_name = 1;
+// string last_name = 2;
+// }
+//
+// {
+// "@type": "type.googleapis.com/google.profile.Person",
+// "firstName": <string>,
+// "lastName": <string>
+// }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+// {
+// "@type": "type.googleapis.com/google.protobuf.Duration",
+// "value": "1.212s"
+// }
+//
+message Any {
+ // A URL/resource name that uniquely identifies the type of the serialized
+ // protocol buffer message. This string must contain at least
+ // one "/" character. The last segment of the URL's path must represent
+ // the fully qualified name of the type (as in
+ // `path/google.protobuf.Duration`). The name should be in a canonical form
+ // (e.g., leading "." is not accepted).
+ //
+ // In practice, teams usually precompile into the binary all types that they
+ // expect it to use in the context of Any. However, for URLs which use the
+ // scheme `http`, `https`, or no scheme, one can optionally set up a type
+ // server that maps type URLs to message definitions as follows:
+ //
+ // * If no scheme is provided, `https` is assumed.
+ // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
+ // value in binary format, or produce an error.
+ // * Applications are allowed to cache lookup results based on the
+ // URL, or have them precompiled into a binary to avoid any
+ // lookup. Therefore, binary compatibility needs to be preserved
+ // on changes to types. (Use versioned type names to manage
+ // breaking changes.)
+ //
+ // Note: this functionality is not currently available in the official
+ // protobuf release, and it is not used for type URLs beginning with
+ // type.googleapis.com.
+ //
+ // Schemes other than `http`, `https` (or the empty scheme) might be
+ // used with implementation specific semantics.
+ //
+ string type_url = 1;
+
+ // Must be a valid serialized protocol buffer of the above specified type.

+// The mixin construct implies that all methods in `AccessControl` are

+// `Storage`. A documentation generator or annotation processor will
+// see the effective `Storage.GetAcl` method after inherting
+// documentation and annotations as follows:

+// service Storage {

+// rpc GetAcl(GetAclRequest) returns (Acl) {

+// Options
+
+// Each of the definitions above may have "options" attached. These are
+// just annotations which may cause code to be generated slightly differently
+// or may contain hints for code that manipulates protocol messages.
+//
+// Clients may define custom options as extensions of the *Options messages.
+// These extensions may not yet be known at parsing time, so the parser cannot
+// store the values in them. Instead it stores them in a field in the *Options
+// message called uninterpreted_option. This field must have the same name
+// across all *Options messages. We then use this field to populate the
+// extensions when we build a descriptor, at which point all protos have been
+// parsed and so all extensions are known.
+//
+// Extension numbers for custom options may be chosen as follows:
+// * For options which will only be used within a single application or
+// organization, or for experimental options, use field numbers 50000
+// through 99999. It is up to you to ensure that you do not use the
+// same number for multiple options.
+// * For options which will be published and used publicly by multiple
+// independent entities, e-mail protobuf-global-extension-registry@google.com
+// to reserve extension numbers. Simply provide your project name (e.g.
+// Objective-C plugin) and your project website (if available) -- there's no
+// need to explain how you intend to use them. Usually you only need one
+// extension number. You can declare multiple options with only one extension
+// number by putting them in a sub-message. See the Custom Options section of
+// the docs for examples:
+// https://developers.google.com/protocol-buffers/docs/proto#options
+// If this turns out to be popular, a web service will be set up

+ //
+ // Notes:
+ // - A location may refer to a repeated field itself (i.e. not to any
+ // particular index within it). This is used whenever a set of elements are
+ // logically enclosed in a single code segment. For example, an entire
+ // extend block (possibly containing multiple extension definitions) will
+ // have an outer location whose path refers to the "extensions" repeated
+ // field without an index.
+ // - Multiple locations may have the same path. This happens when a single
+ // logical declaration is spread out across multiple places. The most
+ // obvious example is the "extend" block again -- there may be multiple
+ // extend blocks in the same scope, each of which will have the same path.
+ // - A location's span is not always a subset of its parent's span. For
+ // example, the "extendee" of an extension declaration appears at the
+ // beginning of the "extend" block and is shared by all extensions within
+ // the block.
+ // - Just because a location's span is a subset of some other location's span
+ // does not mean that it is a descendent. For example, a "group" defines
+ // both a type and a field in a single declaration. Thus, the locations
+ // corresponding to the type and field and their components will overlap.

+// Here `f` represents a field in some root message, `a` and `b`
+// fields in the message found in `f`, and `d` a field found in the
+// message in `f.b`.
+//
+// Field masks are used to specify a subset of fields that should be
+// returned by a get operation or modified by an update operation.
+// Field masks also have a custom JSON encoding (see below).
+//
+// # Field Masks in Projections
+//
+// When used in the context of a projection, a response message or
+// sub-message is filtered by the API to only contain those fields as
+// specified in the mask. For example, if the mask in the previous
+// example is applied to a response message as follows:
+//
+// f {
+// a : 22
+// b {
+// d : 1
+// x : 2
+// }
+// y : 13
+// }
+// z: 8
+//

+// (their value will be set to the default, and omitted in proto text
+// output):
+//
+//
+// f {
+// a : 22
+// b {
+// d : 1
+// }
+// }
+//
+// A repeated field is not allowed except at the last position of a
+// paths string.
+//
+// If a FieldMask object is not present in a get operation, the
+// operation applies to all fields (as if a FieldMask of all fields
+// had been specified).
+//
+// Note that a field mask does not necessarily apply to the
+// top-level response message. In case of a REST get operation, the
+// field mask applies directly to the response, but in case of a REST
+// list operation, the mask instead applies to each individual message
+// in the returned resource list. In case of a REST custom method,
+// other definitions may be used. Where the mask applies will be
+// clearly documented together with its declaration in the API. In
+// any case, the effect on the returned resource/resources is required
+// behavior for APIs.
+//
+// # Field Masks in Update Operations
+//
+// A field mask in update operations specifies which fields of the
+// targeted resource are going to be updated. The API is required
+// to only change the values of the fields as specified in the mask
+// and leave the others untouched. If a resource is passed in to
+// describe the updated values, the API ignores the values of all
+// fields not covered by the mask.
+//
+// If a repeated field is specified for an update operation, new values will
+// be appended to the existing repeated field in the target resource. Note that
+// a repeated field is only allowed in the last position of a `paths` string.
+//
+// If a sub-message is specified in the last position of the field mask for an
+// update operation, then new value will be merged into the existing sub-message
+// in the target resource.
+//
+// For example, given the target message:
+//
+// f {
+// b {
+// d: 1
+// x: 2
+// }
+// c: [1]
+// }
+//
+// And an update message:
+//
+// f {
+// b {
+// d: 10
+// }
+// c: [2]
+// }
+//
+// then if the field mask is:
+//
+// paths: ["f.b", "f.c"]
+//
+// then the result will be:
+//
+// f {
+// b {
+// d: 10
+// x: 2
+// }
+// c: [1, 2]
+// }
+//
+// An implementation may provide options to override this default behavior for
+// repeated and message fields.
+//
+// In order to reset a field's value to the default, the field must
+// be in the mask and set to the default value in the provided resource.
+// Hence, in order to reset all fields of a resource, provide a default
+// instance of the resource and set all fields in the mask, or do
+// not provide a mask as described below.
+//
+// If a field mask is not present on update, the operation applies to
+// all fields (as if a field mask of all fields has been specified).
+// Note that in the presence of schema evolution, this may mean that
+// fields the client does not know and has therefore not filled into
+// the request will be reset to their default. If this is unwanted
+// behavior, a specific service may require a client to always specify
+// a field mask, producing an error if not.
+//
+// As with get operations, the location of the resource which
+// describes the updated values in the request message depends on the
+// operation kind. In any case, the effect of the field mask is
+// required to be honored by the API.
+//
+// ## Considerations for HTTP REST
+//
+// The HTTP kind of an update operation which uses a field mask must
+// be set to PATCH instead of PUT in order to satisfy HTTP semantics
+// (PUT must only be used for full updates).
+//
+// # JSON Encoding of Field Masks
+//
+// In JSON, a field mask is encoded as a single string where paths are
+// separated by a comma. Fields name in each path are converted
+// to/from lower-camel naming conventions.
+//
+// As an example, consider the following message declarations:
+//
+// message Profile {
+// User user = 1;
+// Photo photo = 2;
+// }
+// message User {
+// string display_name = 1;
+// string address = 2;
+// }
+//
+// In proto a field mask for `Profile` may look as such:
+//
+// mask {
+// paths: "user.display_name"
+// paths: "photo"
+// }
+//
+// In JSON, the same mask is represented as below:
+//
+// {
+// mask: "user.displayName,photo"
+// }
+//
+// # Field Masks and Oneof Fields
+//
+// Field masks treat fields in oneofs just as regular fields. Consider the
+// following message:
+//
+// message SampleMessage {
+// oneof test_oneof {
+// string name = 4;
+// SubMessage sub_message = 9;
+// }
+// }
+//
+// The field mask can be:
+//
+// mask {
+// paths: "name"
+// }
+//
+// Or:
+//
+// mask {
+// paths: "sub_message"
+// }
+//
+// Note that oneof type names ("test_oneof" in this case) cannot be used in
+// paths.
+//
+// ## Field Mask Verification
+//
+// The implementation of any API method which has a FieldMask type field in the
+// request should verify the included field paths, and return an
+// `INVALID_ARGUMENT` error if any path is duplicated or unmappable.
+message FieldMask {
+ // The set of field mask paths.
+ repeated string paths = 1;

+// A Timestamp represents a point in time independent of any time zone or local

+// nanosecond resolution. The count is relative to an epoch at UTC midnight on
+// January 1, 1970, in the proleptic Gregorian calendar which extends the
+// Gregorian calendar backwards to year one.
+//
+// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
+// second table is needed for interpretation, using a [24-hour linear
+// smear](https://developers.google.com/time/smear).
+//
+// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
+// restricting to that range, we ensure that we can convert to and from [RFC
+// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
+//
+// # Examples
+//
+// Example 1: Compute Timestamp from POSIX `time()`.
+//
+// Timestamp timestamp;
+// timestamp.set_seconds(time(NULL));
+// timestamp.set_nanos(0);
+//
+// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
+//
+// struct timeval tv;
+// gettimeofday(&tv, NULL);
+//
+// Timestamp timestamp;
+// timestamp.set_seconds(tv.tv_sec);
+// timestamp.set_nanos(tv.tv_usec * 1000);
+//
+// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
+//
+// FILETIME ft;
+// GetSystemTimeAsFileTime(&ft);
+// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
+//
+// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
+// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
+// Timestamp timestamp;
+// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
+// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
+//
+// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
+//
+// long millis = System.currentTimeMillis();
+//
+// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
+// .setNanos((int) ((millis % 1000) * 1000000)).build();
+//
+//
+// Example 5: Compute Timestamp from current time in Python.
+//
+// timestamp = Timestamp()
+// timestamp.GetCurrentTime()
+//
+// # JSON Mapping
+//
+// In JSON format, the Timestamp type is encoded as a string in the
+// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
+// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
+// where {year} is always expressed using four digits while {month}, {day},
+// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
+// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
+// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
+// is required. A proto3 JSON serializer should always use UTC (as indicated by
+// "Z") when printing the Timestamp type and a proto3 JSON parser should be
+// able to accept both UTC and other timezones (as indicated by an offset).
+//
+// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
+// 01:30 UTC on January 15, 2017.
+//
+// In JavaScript, one can convert a Date object to this format using the
+// standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
+// method. In Python, a standard `datetime.datetime` object can be converted
+// to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime)
+// with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one
+// can use the Joda Time's [`ISODateTimeFormat.dateTime()`](
+// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
+// ) to obtain a formatter capable of generating timestamps in this format.
+//
+//
