af17bbfeab 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.

9591d64e53 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.

5df726db68 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%.

bc31ab3d2c 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.

f5f58a7e91 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.

0ea8c8ba67 mempool: drop a level of indirection
`item` is so small that it makes no sense bothering memory allocator with
every instance of it.

53c014a0bb 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.

37f7363386 interop: return struct pointers where needed
`Transaction`, `Block` and `Contract` are represented as
`Array`s in VM, so we must return pointers.

cee1836183 interop: provide missing smartcontract parameter type defs
Contract can have Hash160, Hash256, Signature etc. types which
all map to a `[]byte` in Go. Having synonyms helps us to generate
proper manifest file.

We should check owner witness before adding more tokens to circulation.
Also we shouldn't allow to add to circulation more than TokenSupply
tokens.
