encoding/textpb: add support for MessageSet

This only handles compliant MessageSet extension fields where the field
name has to be message_set_extension.

Current C++ lib allows for different message field names, which is a
possible bug as it makes marshal output possibly contain duplicate names
when more than one field extends the same MessageSet, and makes
unmarshaling confusing as to which field to populate.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
