encoding/jsonschema: improve handling of $id and $ref

Fixes most issues in Issue #378. Remaining problems are mostly
related to invalid JSON schema, if one counts the lack of an $id
field as an invalid schema.

Used Draft 8 (2019-09) as reference.

- Keep stack of $ids
- resolve nested $ids and $refs relative to top stack
- Fixes several bugs
- Allow nested definitions
- Allow references to non-definitions

Note:
- OpenAPI still has its own mechanism. This should be improved at
some point to be more unified with JSON schema.

Also:
- copy metadata in Sanitize

Fixes #378. File separate issues for remaining issues.
