388fed06e5 transaction: forbid serializing invalid transactions
Transaction that has no data is invalid and can't be serialized, so throw an
error if someone tries to.

Merge pull request #579 from nspcc-dev/refactor-crypto
This moves some functionality into micro-packages, improves testing,
unexports some code and fixes bugs along the way.

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.

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.

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.

8d0ed9259c transaction: fix invocation TX consistency in NewInvocationTX()
NewInvocationTX() returned a version number one transaction that actually
failed to pass that version down to the invocation data which lead to
serialization/deserialization inconsistency.

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.

5bf00db2c9 io: move BinReader/BinWriter there, redo Serializable with it
The logic here is that we'll have all binary encoding/decoding done via our io
package, which simplifies error handling. This functionality doesn't belong to
util, so it's moved.

This also expands BufBinWriter with Reset() method to fit the needs of core
package.
