a7cce3f894 smartcontract: use new VerifiableDecodable for ParameterContext 
And implement it for Transaction, the only user of ParameterContext for
now. Which make correct signing/verifying possible for cases when
serialization for general transmission and signing differ.

7b4ca57e33 *: change address to the new format 
NEO3 uses new prefix for address (53 = 0x35), thus string representations as
well as encrypted WIFs should be changed.

941410a840 core: change verification scripts to new format 
Verification scripts now invoke Neo.Crypto.* interops instead of
CHECKSIG/VERIFY opcodes.

1611ede58c crypto/keys: implement NewPublicKeyFromBytes() 
It is convenient to have a single function instead of
allocating new `PublicKey` and using `DecodeBytes()` on it.

9abda40171 testserdes: implement helpers for encode/decode routines 
Frequently one needs to check if struct serializes/deserializes
properly. This commit implements helpers for such cases including:
1. JSON
2. io.Serializable interface

8e05bfe99c rpc/crypto: fix validator field marshalling in getvalidators RPC server 
Problem: wrong `PublicKey` field json marshalling of result.Validator

Solution: add marshaller to publickey (crypto)

a3dacd3b74 tests: replace t.Fatal with require where possible 
This makes tests less verbose and unifies the style
they are written in.

a903147b60 keys: rename Signature to GetScriptHash, make it return Uint160 
Signature itself wasn't used at all and its name is very misleading, Uint160
script hash is way more useful.

32a064aa31 keys: add Cmp method to PublicKey 
It can be used by code that doesn't operate with PublicKeys, but still needs
to be able to compare keys for some purposes.

b5b05a969c keys: make NEP2Decrypt return a PrivateKey rather than WIF 
There is no point in encoding the output of this function in a WIF format,
most of the users actually want the real key and those who need a WIF can
easily get if from the key (and it's simpler than getting the key from the
WIF).

It also fixes a severe bug in NEP2Decrypt, base58 decoding errors were not
processed correctly.

6c471ecd98 keys: move IsOnCurve decoding check, add a test for it 
This check only makes sense for 04-encoded points, because 02 and 03 derive Y
from X and they're on the curve by definition.

369ac01a27 base58: move into its own package 
It doesn't belong to crypto in any way other than it uses hash function
internally.

ddad9ac9a3 hash: simplify merkle tree error handling 
buildMerkleTree() is internal to the hash package and if anyone calls it with
`len(leaves) == 0` he deserves a panic. As it's the only error case in it, we
can remove error value return from this function and simplify NewMerkleTree().

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.

directly to the PublicKey and use it everywhere.
