8c31831626 util: reduce allocations in util.Uint256DecodeStringLE 
It is used a lot in clients (including our benchmark).
`Uint160` is already optimized.

aab18c3083 stackitem: introduce Convertible interface 
We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.

This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.

a6e25cffde bitfield: add basic bit field package 
Strange as it is but I wasn't able to find any good bit field
implementation. Most of them are limited to 64 bits, some allow for wider
values (like https://github.com/emef/bitfield) but even they're not that
efficient (using bytes instead of wider types). This this minimalistic thing.

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.

e299a44983 io: drop Size() method from Serializable and associated 
It's no longer needed after the io.GetVarSize() improvement. It's duplicating
a lot of EncodeBinary() logic also.

0da9fe6946 io: move size calculator there 
It's mostly used for Serializable and in other cases where one needs to
estimate binary-encoded size of the stucture. This also simplifies future
removal of the Size() from Serializable.
