JSON test, symbolic enum names in JSON, and a few improvements.

- Added a JSON test that round-trips (parses then re-serializes) several
  test messages, ensuring that the re-serialized form matches the
  original exactly.
- Added support for printing and parsing symbolic enum names (rather than
  integer values) in JSON.
- Updated JSON printer to properly handle string fields that come in
  multiple pieces. ('bytes' fields still do not support this, and this
  work is more challenging because it requires making the base64 encoder
  resumable. Base64 encoding is not separable at an input-byte
  granularity, unlike string escaping.)
- Fixed a < vs. <= bug in UTF-8 encoding generation (oops).
