in.

c7ab99ddc1 consensus: drop timestamp from outer payload
It's not used really and NEO3 doesn't have it on the wire.

8b3080b972 io: rename Read/WriteBytes to Read/WriteB
go vet is not happy about them:
  pkg/io/binaryReader.go:92:21: method ReadByte() byte should have signature ReadByte() (byte, error)
  pkg/io/binaryWriter.go:75:21: method WriteByte(u8 byte) should have signature WriteByte(byte) error

54d888ba70 io: add type-specific read/write methods
This seriously improves the serialization/deserialization performance for
several reasons:
 * no time spent in `binary` reflection
 * no memory allocations being made on every read/write
 * uses fast ReadBytes everywhere it's appropriate

It also makes Fixed8 Serializable just for convenience.

5b6c5af704 *: implement EncodeBinary with pointer receivers where appropriate
Everywhere except ParamType (which is just a byte), reduce copying things
around for no real reason.

844491d365 *: use more efficient WriteBytes where appropriate
Before this patch on block import we could easily be spending more than 6
seconds out of 30 in Uint256 encoding for UnspentBalance, now it's completely
off the radar.

138e125646 *: remove duplicate functions producing verification script
Drop wif.GetVerificationScript(), drop
smartcontract.CreateSignatureRedeemScript(), add GetVerificationScript()
directly to the PublicKey and use it everywhere.

8d4dd2d2e1 vm: move opcodes into their own package
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

03ff2976ed io: refactoring for using WriteVarBytes instead of WriteLE
goal is to be consistent with C# implementation.
For writing []byte WriteBytes used and for byte - WriteVarByte.
