Title: Fix non-string map key issues in BSON/JSON protos.

This change:
1. Enforces that map keys are strings.
2. Allows a "coerce" mode in TJSONProtocol where map keys are
coerced to strings. This is used only in the implementation
of toString() on records, which just JSON-serialized, and must
work on all structs, even ones with non-string-key maps.
3. Adds various tests around this.
