network: remove priority queue from block queue

8bb1ecb45a network: remove priority queue from block queue 
Use circular buffer which is a bit more appropriate. The problem is that
priority queue accepts and stores equal items which wastes memory even in
normal usage scenario, but it's especially dangerous if the node is stuck for
some reason. In this case it'll accept from peers and put into queue the same
blocks again and again leaking memory up to OOM condition.

Notice that queue length calculation might be wrong in case circular buffer
wraps, but it's not very likely to happen (usually blocks not coming from the
queue are added by consensus and it's not very fast in doing so).

Set all necessary context before file traversal, not only import

processed via `For*` iterators which set necessary context.
We can also refactor this a bit to have all context in one place,
this will be done in #2086.

8e7c76827b core: optimise (*Billet).Traverse and (*Trie).Find 
(*Billet).Traverse changes:
1. Get rid of the `offset` argument. We can cut `from` and pass just the
part that remains. This implies that node with path matching `from` will
also be included in the result, so additional check needs to be added to
the callback function.
2. Pass `path` and `from` without search prefix. Append prefix to the
result inside the callback.
3. Remove duplicating code.

(*Trie).Find changes:
1. Properly prepare `from` argument for traversing function. It closly
depends on the `path` argument.

c009356b73 core: simplify component flushing in storeBlock 
Instead of flushing everything to `cache` and then to `bc.dao`, wrap `bc.dao`
directly for block/tx data and AERs and then flush to it. Block/transactions
are usually processed more quickly than other components, so they easily end
up in `cache` where they directly affect Seek performance for any executing
transaction.

Simple as it is this change improves voter NEO transfer benchmark with 1000
accounts by more than 25%, from ~18500 TPS to ~23500 TPS. It doesn't affect
much other cases.

It will be removed in future as it is surely a protocol parameter.

5cd78c31af core: allow to recover after state jump interruption 
We need several stages to manage state jump process in order not to mess
up old and new contract storage items and to be sure about genesis state data
are properly removed from the storage. Other operations do not require
separate stage and can be performed each time `jumpToStateInternal` is
called.

0e0b55350a core: convert (*Blockchain).JumpToState to a callback 
We don't need this method to be exposed, the only its user is the
StateSync module. At the same time StateSync module manages its state by
itself which guarantees that (*Blockchain).jumpToState will be called
with proper StateSync stage.

6381173293 core: store statesync-related storage items under temp prefix 
State jump should be an atomic operation, we can't modify contract
storage items state on-the-fly. Thus, store fresh items under temp
prefix and replase the outdated ones after state sync is completed.

should be removed from storage. After state sync is completed,
outdated blocks/transactions/AERs should also be removed.

3b7807e897 network: request unknown MPT nodes 
In this commit:

1. Request unknown MPT nodes from peers. Note, that StateSync module itself
shouldn't be responsible for nodes requests, that's a server duty.
2. Do not request the same node twice, check if it is in storage
already. If so, then the only thing remaining is to update refcounter.

a22b1caa3e core: implement MPT Billet structure for MPT restore 
MPT restore process is much simpler then regular MPT maintaining: trie
has a fixed structure, we don't need to remove or rebuild MPT nodes. The
only thing we should do is to replace Hash nodes to their unhashed
counterparts and increment refcount. It's better not to touch the
regular MPT code and create a separate structure for this.

Allow it for (*Trie).Put. And distinguish empty value and nil value for
(*Trie).PutBatch, because batch is already capable of handling both nil
and empty value. For (*Trie).PutBatch putting nil value means deletion,
while putting empty value means just putting LeafNode with an empty
value.

930653418d vm: rework stack as a simple slice 
Double-linked list is quite expensive to manage especially given that it
requires microallocations for each Element. It can be replaced by simple slice
which is much more effective for simple push/pop operations that are very
typical in a VM. I've worried a little about more complex operations like
XDROP/1024 or REVERSEN/1024 because these require copying quite substantial
number of elements, but turns out these work fine too.

At the moment Element is kept as a convenient wrapper for Bytes/BigInt/Bool/etc
methods, but it can be changed in future. Many other potential optimizations
are also possible now.

a68a8aa8fc core: simplify and correct notification handling 
* both 'to' and 'from' are either Null or Hash160, there is no other
   possibility for valid NEP-17. So returning util.Uint160{} in case of
   parsing error is wrong.
 * but this is what allowed burns/mints to work at the expense of error
   allocation inside of util.Uint160DecodeBytesBE()
 * Uint160 can technically fit into regular VM integer, so even though it'd be
   quite surprising to see it there, TryBytes() is more correct (and easier!)
   to use
 * same thing with `amount`, we have `TryInteger()` that easily covers all
   possible cases and does appropriate error checking inside

ae071d4542 storage: introduce PutChangeSet and use it for Persist 
We're using batches in wrong way during persist, we already have all changes
accumulated in two maps and then we move them to batch and then this is
applied. For some DBs like BoltDB this batch is just another MemoryStore, so
we essentially just shuffle the changeset from one map to another, for others
like LevelDB batch is just a serialized set of KV pairs, it doesn't help much
on subsequent PutBatch, we just duplicate the changeset again.

So introduce PutChangeSet that allows to take two maps with sets and deletes
directly. It also allows to simplify MemCachedStore logic.

bdb2d24a5a vm: remove istack redirection in VM 
VM always has istack and it doesn't even change, so doing this microallocation
makes no sense. Notice that estack is a bit harder to change we do replace it
in some cases and we compare pointers to it as well.

7bb82f1f99 network: merge two loops in iteratePeersWithSendMsg, send to 2/3 
Refactor code and be fine with sending to just 2/3 of proper peers. Previously
it was an edge case, but it can be a normal thing to do also as broadcasting
to everyone is obviously too expensive and excessive (hi, #608).

Baseline (four node, 10 workers):

RPS    8180.760 8137.822 7858.358 7820.011 8051.076 ≈ 8010   ± 2.04%
TPS    7819.831 7521.172 7519.023 7242.965 7426.000 ≈ 7506   ± 2.78%
CPU %    41.983   38.775   40.606   39.375   35.537 ≈   39.3 ± 6.15%
Mem MB 2947.189 2743.658 2896.688 2813.276 2863.108 ≈ 2853   ± 2.74%

Patched:

RPS    9714.567 9676.102 9358.609 9371.408 9301.372 ≈ 9484   ±  2.05% ↑ 18.40%
TPS    8809.796 8796.854 8534.754 8661.158 8426.162 ≈ 8646   ±  1.92% ↑ 15.19%
CPU %    44.980   45.018   33.640   29.645   43.830 ≈   39.4 ± 18.41% ↑  0.25%
Mem MB 2989.078 2976.577 2306.185 2351.929 2910.479 ≈ 2707   ± 12.80% ↓  5.12%

There is a nuance with this patch however. While typically it works the way
outlined above, sometimes it works like this:

RPS ≈ 6734.368
TPS ≈ 6299.332
CPU ≈ 25.552%
Mem ≈ 2706.046MB

And that's because the log looks like this:

On a network with 4 CNs and 1 RPC node there is 1/256 probability that a block
won't be broadcasted to RPC node, so it won't see it until ping timeout kicks
in. While it doesn't see a block it can't accept new incoming transactions so
the bench gets stuck basically. To me that's an acceptable trade-off because
normal networks are much larger than that and the effect of this patch is way
more important there, but still that's what we have and we need to take into
account.

966a16e80e network: keep track of dead peers in iteratePeersWithSendMsg() 
send() can return errStateMismatch, errGone and errBusy. errGone means the
peer is dead and it won't ever be active again, it doesn't make sense retrying
sends to it. errStateMismatch is technically "not yet ready", but we can't
wait for it either, no one knows how much will it take to complete
handshake. So only errBusy means we can retry.

So keep track of dead peers and adjust tries counting appropriately.
