07c2105aa5 core: log values from the store in persist()
We're about stored values here, so print those, which avoids blocking in
bc.HeaderHeight() and removes duplication between blockHeight and
persistedHeight. Fixes saving the blockchain on exit (deferred function in
Run() blocked in persist()).

Test modification was required because storeBlocks() doesn't actually save
headers and thus TestGetTransaction started to fail on persist().

b533dfceba core: don't panic on init when there are less than 2000 hashes
If you're to sync less than 2000 headers no batched header key-value is
gonna be written into the DB and init() would panic because
bc.headerList.Len() would return 0. Use genesis block as a target in this
case.

Merge pull request #427 from nspcc-dev/feat/max_size
Arrays, Structs and Maps have maximum size defined as MaxArraySize.
We need to return an error in case collection becomes too big.
Part of #373.

3f6104ef4d network: ignore consensus messages
It's a temporary stub until proper encoding/decoding is implemented. It's
useful for testnet/mainnet connections because without it consensus message
receival leads to peer disconnection.

56459c6c63 network: remove port check from handleVersionCmd()
It's bogus and no other node implementation has anything like that. It fires
up for no good reason in the case when some other node connects to us and it
obviously doesn't use its listening port for it.

now that can easily substitute for a Batch, especially given that interop

a6610ba082 core: verify blocks, fix #12
This adds the following verifications:
 * merkleroot check
 * index check
 * timestamp check
 * witnesses verification

VerifyWitnesses is also renamed to verifyTxWitnesses here to not confuse it
with verifyBlockWitnesse and to hide it from external access (no users at the
moment).

03c20f1876 core: make ContractState receiver names consistent
Linter isn't happy with our recent changes:

pkg/core/contract_state.go:109:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:114:1: receiver name cs should be consistent with previous receiver name a for ContractState
pkg/core/contract_state.go:119:1: receiver name cs should be consistent with previous receiver name a for ContractState

But actually `a` here most probably is a copy-paste from AssetState methods,
so fit the old code to match the new one.
