vm/core: improve block import speed with PublicKey caching
...
This change (closely related to the neo-project/neo#1321 proposal) speeds up
1.4M mainnet blocks import by 30%. Basically, we're eliminating key decoding
for block's multisignature that has the same keys most of the time.
Things I don't like about this patch:
* yet another parameter for verifyHashAgainstScript()
* vm keys are not copied in/out
But it's rather simple and solves the problem for this particular case, so I
think it's worth it.

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.

vm: copy slice in NEWARRAY/NEWSTRUCT

When performing NEWARRAY on a Struct or NEWSTRUCT on a Array,
underlying slice needs to be copied, because when it's capacity
doesn't matches it's length, underlying storage will be used
for appends even if it is already pointed at by another slice.
