For JSON encoding we provide a new option to decide at
encode time whether to use camelCase or original proto field
names:
json = MapMessage.encode_json(m, :preserve_proto_fieldnames => true)
The flags are:
UPB_JSON_ACCEPT_LEGACY_FIELD_NAMES
UPB_JSON_WRITE_LEGACY_FIELD_NAMES
The first just allows the parser to accept the old field names.
The second makes the printer print the old field names.
These flags are intended to be temporary, as a migration aid
for users.
This involved fixing a few important bugs in the
Ruby implementation -- mostly cases of mixing
upb field types and descriptor types (upb field
types do not distinguish between int/sint/fixed/sfixed
like descriptor types do).
Also added protobuf-specific exceptions so parse
errors can be caught specifically.

While we are C99 in general, the Ruby build system
for building C extensions enables several flags that
throw warnings for C89/C90 variable ordering rules.
To avoid spewing a million warnings (or trying to
specifically override these warnings with command-line
flags, which would be tricky and possibly fragile)
we conform to Ruby's world of C89/C90.

- Alter encode/decode paths to use the `upb_env` (environment)
abstraction.
- Update upb amalgamation to upstream `93791bfe`.
- Fix a compilation warning (void*->char* cast).
- Modify build flags so that upb doesn't produce warnings -- the Travis
build logs were pretty cluttered previously.
* make consistent between mri and jruby
* create a #to_h and have it use symbols for keys
* add #to_json and #to_proto helpers on the Google::Protobuf message classes
Previously, we supported map fields in the Ruby DSL. However, we never
connected the final link in the chain and generated `map` DSL commands
for map fields in `.proto` files. My apologies -- I had been testing
with the DSL directly so I missed this.
Also fixed a handlerdata-setup-infinite-loop when a map value field's
type is its containing message.
This adds the Map container and support for parsing and serializing maps
in the protobuf wire format (as defined by the C++ implementation, with
MapEntry submessages in a repeated field). JSON map
serialization/parsing are not yet supported as these will require some
changes to upb as well.
