internal/encoding/json: rewrite to a token-based encoder and decoder

Previous decoder decodes a JSON number into a float64, which lacks
64-bit integer precision.

I attempted to retrofit it with storing the raw bytes and parsed out
number parts, see golang.org/cl/164377.  While that is possible, the
encoding logic for Value is not symmetrical with the decoding logic and
can be confusing since both utilizes the same Value struct.

Joe and I decided that it would be better to rewrite the JSON encoder
and decoder to be token-based instead, removing the need for sharing a
model type plus making it more efficient.

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.
