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.

f77c239296 mpt: fix extension node cache invalidation 
It should always be invalidated if something changes in the `next` (below the
extension node).

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.

e4f413aa29 consensus: update dbft to include CountFailed and RecoveryMessage changes 
dbft interface changed a little also because of Neo 3 changes, but it still is
compatible with Neo 2.

103c45850a mpt: implement (*Trie).Collapse() 
Because trie size is rather big, it can't be stored in memory.
Thus some form of caching should also be implemented. To avoid
marshaling/unmarshaling of items which are close to root and are used
very frequenly we can save them across the persists.
This commit implements pruning items at the specified depth,
replacing them by hash nodes.

9c478378e1 mpt: implement JSON marshaling/unmarshaling 
Because there is no distinct type field in JSONized nodes, distinction
is made via payload itself, thus all unmarshaling is done via
NodeObject.

b0d07c3031 vm: make Iterator interface public 
There is nothing wrong with iterators being implemented in other parts
of code (e.g. Storage.Find). In this case type assertions can
prevent bugs at compile-time.
