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.

16-element alphabet.

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.

Reproduce behavior of the reference realization:

- checking if item is in cache must be performed in real-time
  during `Iterator.Next()`

bafdb916a0 change was wrong (probably brought

doesn't allow PICKITEM for arbitrary types.

b96fe8173c core,dao: implement Block-level storage caching
The order in which storage.Find items are returns depends on what items
were processed in previous transactions of the same block.
The easiest way to implement this sort of caching is to cache operations
with storage, flushing the only in `Persist()`.

a587274351 compiler|transaction: remove transaction.GetUnspentCoins support
It's useless. Even though there is Neo.Transaction.GetUnspentCoins syscall
that can be used, its return type is an interop structure that's not accepted
by any other syscall, so you can't really do anything with it. And there is no
such interface for the .net Framework.
