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.

ad606101c7 storage: add SeekGC interface for GC
It's very special, single-purpose thing, but it improves cumulative time spent
in GC by ~10% for LevelDB and by ~36% for BoltDB during 1050K mainnet chain
processing. While the overall chain import time doesn't change in any
noticeable way (~1%), I think it's still worth it, for machines with slower
disks the difference might be more noticeable.

a5f8b8870a storage: use Update for changeset processing
Batch is only relevant in multithreaded context, internally it'll do some
magic and use the same locking/updating Update does, so it makes little sense
for us. This doesn't change benchmarks in any noticeable way.

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.

8af9c870b1 compiler: remove CompileWithDebugInfo
It is a simple wrapper over `CompileWithOptions` which we don't really
need. Custom options can be specified explicitly instead of using some
random default. This default was introduced in 1578904da, however tests
written there use `CompileWithOptions` and all other tests
pass on that commit even without this default.

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.
