9441c5e77b rpc: split README into developer and user parts 
Most of the document is written for developers and thus belongs to
godoc. User-related document is now moved to docs as per #339.

0bb8950f89 make TXer and Payload implement Serializable 
Both are duplicating Serializable at the moment, but let's keep them for the
future.

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.

56c72b5c67 io: redo GetVarSize for Serializable things 
Use writes to a fake io.Writer that counts the bytes. Allows us to kill Size()
methods as useless and duplicating lots of functionality.

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.

Roman Khimov
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.

Merge pull request #396 from nspcc-dev/network-reconnections-and-fixes 
This one fixes #390 and some connected problems. After this patchset the node reconnects to some other nodes if anything goes wrong and it better senses when something goes wrong. It also fixes some block handling problems based on the testnet connection experience.

773ccc2b92 network: allow discoverer to reuse addresses 
...and don't try to connect to the nodes we're already connected to.

Before this change we had a problem of discoverer throwing away good valid
addresses just because they are already known which lead to pool draining over
time (as address reuse was basically forbidden and getaddr may not get enough
new nodes).

d3bb8ddf8f network: handle errors and connection close more correctly 
This makes writer side handle errors properly and fixes communication between
reader and writer goroutine to always correctly unregister the peer. This is
especially important for the case where error occurs before handshake
completes as in this case we don't even have goroutine in startProtocol()
running.

4395cea344 storage: fix reading overlapping hash blocks from the DB 
In the unlikely event of overlapping hash block written to the DB we might end
up with wrong hash list. That happened to me for some reason when synching
with the testnet leading to the following keys with respective values:
  150000 -> 2000 hashes
  152000 -> 2000 hashes
  153999 -> 2000 hashes

Reading it hashes number 153999 and 154000 got the same values and the chain
couldn't sync correctly.

e537dc9ee4 keys: improve publick key checks with a check against P 
ANSI X9.62 says that if x or y coordinate are greater than or equal to
curve.Params().P, the conversion should return an error (see ANSI X9.62:2005
Section A.5.8 Step b, which invokes Section A.5.5, which does the check and
rejects when x or y are too big.

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.

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

ec7e17ffa6 pkg: make use of the new crypto/hash package 
Simplifies a lot of code and removes some duplication. Unfortunately I had to
move test_util random functions in same commit to avoid cycle
dependencies. One of these random functions was also used in core/transaction
testing, to simplify things I've just dropped it there and used a static
string (which is nice to have for a test anyway).

There is still sha256 left in wallet (but it needs to pass Hash structure into
