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.

d0f9a28196 vm/core: improve block import speed with PublicKey caching
This change (closely related to the neo-project/neo#1321 proposal) speeds up
1.4M mainnet blocks import by 30%. Basically, we're eliminating key decoding
for block's multisignature that has the same keys most of the time.

Things I don't like about this patch:
 * yet another parameter for verifyHashAgainstScript()
 * vm keys are not copied in/out

But it's rather simple and solves the problem for this particular case, so I
think it's worth it.

Merge pull request #549 from nspcc-dev/serialization-and-struct-improvements
Serialization and struct improvements

This set improves serialization/deserialization performance and, more
importantly, simplifies memory management for some structures avoiding
useless copying.

It adds some percents to the 1,4M blocks import test.

35e368c241 io: add a note for WriteArray, fix #519
It can't be really solved in many cases (it's used in P2P protocol and we have
to follow the usual conventions there) and in most of the cases we don't care
about the difference between nil slice and zero-length slice.

f1856bfa8b core/tx: remove publickey indirection from assets and txes
It makes very little sense having pointers here, these structures MUST have
some kind of key and this key is not gonna be wandering somewhere on its
own. Fixes a part of #519.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.

b542a5e7a0 io: add support for pointer receivers in WriteArray()
It's actually preferable to have pointer receivers for serializable types, so
this should be supported.

1784a14148 io: optimize BinReader.ReadArray()
reflect.MethodByName is a rather expensive function especially when
called on hot path. This became obvious during profiling of db restore.
This commit replaces reflection with a cast to an interface.

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.

e7687d620d io: simplify WriteBytes()
Which speeds it up at least twofold for a typical 32-bytes write (and that's
for a very naïve test that allocates new BufBinWriter on every iteration):

c034aae378 core: fix wrong data being read in interops (part of #501)
When 74590551 introduced this code we had no proper caching layer, so there
were these strange fallbacks in the code. fc0031e5 should'd removed them, but
failed to do so, so do it now and fix processing of transactions that touch
storage for the same key (address) in the same block.
