internal/impl: pull out message struct info into a type

Minor refactoring of impl.MessageType initialization: Pull the
information gathered about a message struct by makeKnownFieldsFunc out
into a struct that we can pass around.

At the moment, makeKnownFieldsFunc is the only user of this struct, but
this will simplify the table (un)marshaler.

Drop the 'specialByName' map indexing XXX_ fields because it currently
isn't used anywhere.

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.
