consensus: refactor payloads structure
...
1. `Version` and `PrevHash` are now in `PrepareRequest`.
2. Serialization is done via `Extensible` payload.
3. Update dbft version.

consensus: assume non-nil message in decodeData
...
`nil` message is occuring only in tests to check that
no unnecessary decoding is done on errors.

crypto/consensus: sign hashes and cache them for consensus payloads
...
Avoid serializing payload again and again for various purposes. To sign it, we
only need a hash.
Some 2.4% gain in TPS could be achieved with this.

remove github.com/pkg/errors from dependencies
...
It's not needed any more with Go 1.13 as we have wrapping/unwrapping in base
packages. All errors.Wrap calls are replaced with fmt.Errorf, some strings are
improved along the way.

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

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.

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.
