edd60e656e consensus: fix processing changeview payloads from recovery message 
Using view number from the recovery message is just plain wrong, it's gonna be
higher than our current view and these messages will be treated as coming from
the future, even though they have their original view number included.

a1c4d7ce26 core: do MPT compaction every once in a while 
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

e3af560d11 dao: optimize storage cache flushing 
Items were serialized several times if there were several successful
transactions in a block, prevent that by using State field as a bitfield (as
it almost was intended to) and adding one more bit. It also eliminates useless
duplicate MPT traversions.

Confirmed to not break storage changes up to 3.3M on testnet.

69ccca675d core: fix PrevHash calculation for MPTRoot 
This was differing from C# notion of PrevHash. It's not a previous root, but
rather a hash of the previous serialized MPTRoot structure (that is to be
signed by CNs).

685d3eb870 dao: prevent double serialization of StorageItems 
Converting to MPT value serializes the StorageItem, so it makes no sense doing
it again.

6c06bc57cc core: implement key recover interops 
Implement secp256k1 and secp256r1 recover interops, closes #1003.

Note:

We have to implement Koblitz-related math to recover keys properly
with Neo.Cryptography.Secp256k1Recover interop as far as standard
go elliptic package supports short-form Weierstrass curve with a=-3
only (see https://github.com/golang/go/issues/26776 for details).
However, it's not the best choise to have a lot of such math in our
project, so it would be better to use ready-made solution for
Koblitz-related cryptography.
