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

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)

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.

d1a4e43c48 io: redo Serializable to return errors in BinReader/BinWriter

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.

2c3e92923f keys: simplify error handling for PublicKey() and associated
PublicKey() for PrivateKey now just can't fail and it makes no sense to return
an error from it. There is a lot of associated functionality for which this
also is true, so adjust it accordingly and simplify a lot of code.

f0fbe9f6c9 crypto: drop home-grown elliptic crypto, use crypto/elliptic
As NEO uses P256 we can use standard crypto/elliptic library for almost
everything, the only exception being decompression of the Y coordinate. For
some reason the standard library only supports uncompressed format in its
Marshal()/Unmarshal() functions. elliptic.P256() is known to have
constant-time implementation, so it fixes #245 (and the decompression using
big.Int operates on public key, so nobody really cares about that part being
constant-time).

New decompress function is inspired by
https://stackoverflow.com/questions/46283760, even though the previous one
really did the same thing just in a little less obvious way.

0b884b92b3 crypto: use PrivateKey to generate a key pair
It makes no sense to provide an API for throw-away public keys, so obtain it
via a new real keypair generation where appropriate (and that's only needed
for testing).

b77e533d13 crypto/wallet: move public/private key into the new keys package
And drop associated _pkg.dev remnants (refs. #307).

Original `dev` branch had two separate packages for public and private keys,
but those are so intertwined (`TestHelper` subpackage is a proof) that it's
better unite them and all associated code (like WIF and NEP-2) in one
package. This patch also:
 * creates internal `keytestcases` package to share things with wallet (maybe
   it'll be changed in some future)
 * ports some tests from `dev`
 * ports Verify() method for public key from `dev`
 * expands TestPrivateKey() with public key check
