f1856bfa8b core/tx: remove publickey indirection from assets and txes 
It makes very little sense having pointers here, these structures MUST have
some kind of key and this key is not gonna be wandering somewhere on its
own. Fixes a part of #519.

5b6c5af704 *: implement EncodeBinary with pointer receivers where appropriate 
Everywhere except ParamType (which is just a byte), reduce copying things
around for no real reason.

7e371588a7 core/tx: remove one layer of indirection for scripts and inouts 
It reduces heap pressure a little for these elements as we don't have to
allocate/free them individually. And they're directly tied to transactions or
block, not being shared or anything like that, so it makes little sense for
them to be pointer-based. It only makes building transactions a little easier,
but that's obviously a minor usecase.

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.

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.

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.

467c9c146d core: restore intermediate block-level store 
Commit c80ee952a1 removed temporary store used
to contain changes of the block being processed. It's wrong in that the block
changes should be applied to the database in a single transaction so that
there wouldn't be any intermediate state observed from the outside (which is
possible now). Also, this made changes commiting persist them to the
underlying store effectively making our persist loop a no-op (and not
producing `persist completed` log lines that we love so much).
