encoding/prototext: rewrite of internal/encoding/text
...
* Fixes golang/protobuf#842 . Unmarshal can now parse singular or
repeated message fields without the field separator.
* Fixes golang/protobuf#1011 . Handles negative 0 properly.
* For unknown fields with fixed 32-bit and 64-bit wire types, output is
now in hex format with 0x prefix similar to C++ lib output. Previous
Go implementation simply outputs these as decimal numbers %d.
* All parsing errors, except for unexpected EOF should now contain line
and column number info.
* Fixed following conformance-related features:
* Parse nan,inf,-inf,infinity,-infinity as case-insensitive.
* Interpret float32 overflows as inf or -inf.
* Parse large int-like number as proto float.
* Discard unknown map field if DiscardUnknown=true.
* Allow whitespaces/comments in Any type URL and extension field names per spec.
* Improves performance and memory usage. It is now as fast and efficient as
protojson, if not better on most benchmarks.
