54bc603831 core: remove old storage items synchronously during jump 
There won't be a lot of them and GC experience we have shows that iterating
over 1-2M of entries is not a huge problem for DBs we have.

3a2b800e5f core: remove stale transfer entries, fix #2096 
Initially I thought of doing it in the next persist cycle, but testing shows
that it needs just ~2-5% of the time MPT GC does, so doing it in the same
cycle doesn't affect anything.

ccdda21718 stateroot: add and use DataMPTAux for auxiliary data 
Use DataMPT for nodes only, otherwise with 1M blocks with have 1M
height-stateroot mapping entries that our GC has to iterate over for no
reason.

423c7883b8 core: implement basic GC for value-based storage scheme 
The key idea here is that even though we can't ensure MPT code won't make the
node active again we can order the changes made to the persistent store in
such a way that it practically doesn't matter. What happens is:
 * after persist if it's time to collect our garbage we do it synchronously
   right in the same thread working the underlying persistent store directly
 * all the other node code doesn't see much of it, it works with bc.dao or
   layers above it
 * if MPT doesn't find some stale deactivated node in the storage it's OK,
   it'll recreate it in bc.dao
 * if MPT finds it and activates it, it's OK too, bc.dao will store it
 * while GC is being performed nothing else changes the persistent store
 * all subsequent bc.dao persists only happen after the GC is completed which
   means that any changes to the (potentially) deleted nodes have a priority,
   it's OK for GC to delete something that'll be recreated with the next
   persist cycle

Otherwise it's a simple scheme with node status/last active height stored in
the value. Preliminary tests show that it works ~18% worse than the simple
KeepOnlyLatest scheme, but this seems to be the best result so far.

Fixes #2095.

c4ee310e85 mpt: modify refcounted storage scheme to make GC possible 
Add "active" flag into the node data and make the remainder modal, for active
nodes it's a reference counter, for inactive ones the deactivation height is
stored.

Technically, refcounted chains storing just one trie don't need a flag, but
it's a bit simpler this way.

86cb4ed80f mpt: add the notion of MPT mode 
It directly affects the storage format, so it's important. ModeGC is not used
at the moment, but defined for future extensibility.

cda1c75db3 core: drop GetStandBy* methods 
They're misleading now that we have variable number of committee
members/validators. The standby list can be seen in the configuration and the
appropriate numbers can be received from it also.

9b841b9b8f core, rpc: use Seek to iterate over NEP* transfers 
The results are controversial a bit. MemoryPS is a special storage
and the new approach doesn't help it to iterate through NEP17 transfers.
However, on long distances (if transfers are requested for more than
1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and
BoltDB perform good enough with the new approach. Taking into account
the fact that default value for the query period of `getnep17transfers`
RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS
performance in favour of BoltDB and LevelDB optimisation.

Close #2263.

cd42b8b20c core: allow early Seek stop 
This simple approach allows to improve the performance of
BoltDB and LevelDB in both terms of speed and allocations
for retrieving GasPerVote value from the storage.
MemoryPS's speed suffers a bit, but we don't use it for
production environment.

Part of #2322.

4c39b6600d *: store application long along with tx/block 
Two times less keys inserted into the DB per tx leads to ~13% TPS
improvement. We also drop one goroutine with it which isn't bad as well.

This commit allows to parametrize dao with the default prefix.

5fbe838fd4 core: add and use synchronous persist to avoid OOM 
b9be892bf9 has made Persist asynchronous which
is very effective in allowing the system to continue processing
blocks/transactions while flushing things to disk. It at the same time is very
dangerous in that if the disk is slow and it takes much time to flush KV set
(more than persisting interval), there might be even bigger new KV set in
MemCachedStore by the time it finishes. Even if the system immediately starts
to flush this new data set it (being bigger) can take more time than the
previous one. And while doing so a new data set will appear in memory,
potentially again bigger than this.

So we can easily end up with the system going out of control, consuming more
and more memory and taking more and more time to persist a single set of
data. To avoid this we need to detect such condition and just wait for Persist
to really finish its job and release the resources.

else. Variable/function names of course can use whatever fits, but documents

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.

are properly removed from the storage. Other operations do not require
separate stage and can be performed each time `jumpToStateInternal` is
called.
