9992a98007 core: optimize balance utxo removal 
One of my samples had 8 (out of 30) seconds spent here, but values of 100ms
are more typical. After this change it becomes invisible.

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.

e7687d620d io: simplify WriteBytes() 
Which speeds it up at least twofold for a typical 32-bytes write (and that's
for a very naïve test that allocates new BufBinWriter on every iteration):

pkg: github.com/CityOfZion/neo-go/pkg/io
BenchmarkWriteBytes-8           10000000               124 ns/op
BenchmarkWriteBytesOld-8         5000000               251 ns/op

c034aae378 core: fix wrong data being read in interops (part of #501) 
When 74590551 introduced this code we had no proper caching layer, so there
were these strange fallbacks in the code. fc0031e5 should'd removed them, but
failed to do so, so do it now and fix processing of transactions that touch
storage for the same key (address) in the same block.

c8aa061421 cli/wallet: use more secure way to read passwords 
They were printed in plaintext, believe it or not. Also, `ssh/terminal` does
some proper magic to really read something from the terminal.

Merge pull request #538 from nspcc-dev/opcode-and-related 
To use opcode definitions you have to import whole vm package that you might
not care about at all. So this moves opcodes to their own package under vm, fixes
and deduplicate related code and moves compiler package up one level.

852e6a335b compiler: move it up from vm 
It really deserves it, I think. Especially given that it doesn't have any
direct usage of `vm` package now.

138e125646 *: remove duplicate functions producing verification script 
Drop wif.GetVerificationScript(), drop
smartcontract.CreateSignatureRedeemScript(), add GetVerificationScript()
directly to the PublicKey and use it everywhere.

8d4dd2d2e1 vm: move opcodes into their own package 
This allows easier reuse of opcodes and in some cases allows to eliminate
dependencies on the whole vm package, like in compiler that only needs opcodes
and doesn't care about VM for any other purpose.

And yes, they're opcodes because an instruction is a whole thing with
operands, that's what context.Next() returns.

The problem is that we're modifying `unsortedTxn` under a reader lock.
