Create "cjson" Lua module, support UCS-2 escapes

- Convert lua_json_init() into luaopen_cjson() to support dynamic .so
  loading.
- Rename "json" to "cjson" to reduce conflicts with other JSON modules.
- Remove unnecessary *_pcall_* API. Lua calls are fast enough,
  even through C.
- Encode empty tables as objects
- Add support for decoding all UCS-2 escape codes.
