They're useful as wrappers around EncodeBinaryStackItem/DecodeBinaryStackItem.

7e7ce7f19f vm: rephrase serialization errors
Seeing some
    blockQueue: failed adding block into the blockchain        {"error": "failed to store notifications: not supported", "blockHeight": 713984, "nextIndex": 713985}
in logs is not very helpful.

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.

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.

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.

7080b78a6b vm: fix a bug in collection serialize
When encountering already seen stack item we should fail
only if it is a collection. Duplicate Integers or ByteArrays are ok
because they can't lead to recursion.
