Also added json.Decoder.Clone API for unmarshaling Any to look
ahead remaining bytes for @type field.

Per Joe's suggestion, remove producing numberParts when parsing a JSON
number to produce corresponding Value. This saves having to store it
inside Value as well. Only produce numberParts for calls to
Value.{Int,Uint} call.
numberParts is only used for producing integers and removing the logic to
produce numberParts improves overall decoding speed for floats, and shows no
change for integers.

Unmarshaling of scalar, messages, repeated, and maps.
Need to further improve on error messages for consistency, some error
messages contain the position info while some currently do not. There
are cases where position info is wrong as well when a value is decoded
in another pass, e.g. numbers in string value, or map keys.

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.

This change was created by running:
git ls-files | xargs sed -i "s|google.golang.org/proto|github.com/golang/protobuf/v2|g"
This change is *not* an endorsement of "github.com/golang/protobuf/v2" as the
final import path when the v2 API is eventually released as stable.
We continue to reserve the right to make breaking changes as we see fit.
This change enables us to host the v2 API on a repository that is go-gettable
(since go.googlesource.com is not a known host by the "go get" tool;
and google.golang.org/proto was just a stub URL that is not currently served).
Thus, we can start work on a forked version of the v1 API that explores
what it would take to implement v1 in terms of v2 in a backwards compatible way.

Package json provides a parser and serializer for the JSON format.
This focuses on the grammar of the format and is agnostic towards specific
semantics of protobuf types.
High-level API:
func Marshal(v Value, indent string) ([]byte, error)
func Unmarshal(b []byte) (Value, error)
type Type uint8
const Null Type ...
type Value struct{ ... }
func ValueOf(v interface{}) Value
func (v Value) Type() Type

func (v Value) Number() float64
func (v Value) String() string
func (v Value) Array() []Value
func (v Value) Object() [][2]Value
