Instead of tick-tocking with sync/async and having an unpredictable data
set we can just try to check for the real amount of keys that be processed
by the underlying DB. Can't be perfect, but still this adds some hard
limit to the amount of in-memory data. It's also adaptive, slower machines
will keep less and faster machines will keep more.
This gives almost perfect 4s cycles for mainnet BoltDB with no tail cutting,
it makes zero sense to process more blocks since we're clearly DB-bound:

2× can be considered, but this calculation isn't perfect for low number of
keys, so somewhat bigger tolerance is preferable for now. Overall it's not
degrading performance, my mainnet/bolt run was even 8% better with this.
Fixes #3249, we don't need any option this way.
Fixes #3783 as well, it no longer OOMs in that scenario. It however can OOM in
case of big GarbageCollectionPeriod (like 400K), but this can't be solved easily.
