core: reuse mempool from AddBlock() for bc.isTxStillRelevant()
...
It's already there most of the time and creating another slice is just a waste
of time. Checking for presence with map is also a little faster.

rpc/server: encode answers more efficiently

We're at the point where even this code can clearly be seen in profiles. We
can save on some buffers (and CPU cycles) by encoding the answer once.
Another ~2% TPS for single node.

mempool: don't sort items by hash
...
There is nothing requiring us to do so. It also is bad because it allows for
new transaction to replace some already existing one with the same fee
parameters just because it has "better" hash.
But the other thing is that for transactions with equal fees it's always
better for us to append them to the end of the list, instead of inserting them
in the middle, so this change allows to reduce slice item movements and gain
some 6-7% increase for single-node TPS.

mempool: replace timeStamp with blockStamp
...
Time is not really relevant for us here and we don't use this timestamp in any
way. Yet it occupies 24 bytes and we do two clock_gettime calls to get it.
Replace it with blockStamp which is going to be used in the future for
transaction retransmissions.
It allows to improve single-node TPS by another 3%.

storage: add bloom filter to leveldb
...
We're constantly checking for transactions there and most of the time this
check is not successful (meaning that the transaction in question is
new). Bloom filter easily reduces the need to search over the DB in 99% of
these cases and gives some 13% increase in single-node TPS.

keys: add simple LRU key cache for 1024 elements

The cost of Y calculation from X is comparable with signature check, so it
reduces witness check overhead by ~30% for cached keys and gives ~5% overall
boost in TPS.

crypto/consensus: sign hashes and cache them for consensus payloads

Avoid serializing payload again and again for various purposes. To sign it, we
only need a hash.
Some 2.4% gain in TPS could be achieved with this.
