internal/encoding/wire: initial commit

This adds package wire, which provides low-level functionality for
marshaling and unmarshaling the protobuf wire format.

High-level API:
	type Number int32
	    const MinValidNumber Number = 1 ...
	type Type int8
	    const VarintType Type = 0 ...
	func ParseError(n int) error

	func ConsumeField(b []byte) (Number, Type, int)
	func ConsumeFieldValue(num Number, typ Type, b []byte) (n int)
	func ConsumeTag(b []byte) (Number, Type, int)
	func ConsumeVarint(b []byte) (v uint64, n int)
	func ConsumeFixed32(b []byte) (v uint32, n int)
	func ConsumeFixed64(b []byte) (v uint64, n int)
	func ConsumeBytes(b []byte) (v []byte, n int)
	func ConsumeGroup(num Number, b []byte) (v []byte, n int)
	func AppendTag(b []byte, num Number, typ Type) []byte
	func AppendVarint(b []byte, v uint64) []byte
	func AppendFixed32(b []byte, v uint32) []byte
	func AppendFixed64(b []byte, v uint64) []byte
	func AppendBytes(b []byte, v []byte) []byte
	func AppendGroup(b []byte, num Number, v []byte) []byte
	func SizeTag(num Number) int
	func SizeVarint(v uint64) int
	func SizeFixed32() int
	func SizeFixed64() int
	func SizeBytes(n int) int
	func SizeGroup(num Number, n int) int

	func DecodeBool(x uint64) bool
	func DecodeTag(x uint64) (Number, Type)
	func DecodeZigZag(x uint64) int64
	func EncodeBool(x bool) uint64
	func EncodeTag(num Number, typ Type) uint64
	func EncodeZigZag(x int64) uint64
