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.
