2e876b5593 block: remove Base.Verify() 
It's a no-op and there is nothing we can do about it, header contents could
only be checked against chain state, there is nothing to check for internal
consistency.

d52e79668b hash: introduce memory-optimized merkle root hash calculation routine 
NewMerkleTree is a memory hog, we can do better than that:

bcc11cbd74 compiler: support removing slice elements 
Go-way of removing elements from slice is via `append` builtin.
There is a separate opcode for removing elements from
Arrays, which is cheaper and supported in this commit.

78948ef7af compiler: emit error for non-byte subslices 
They are not supported for now, as VM has only
`SUBSTR` opcode for Buffers (`[]byte` in Go).

fc7ea6217d mempool: avoid reassigning utilityBalanceAndFees value 
It's not needed, we're either creating a new one and assigning it 6 lines
above or we're changing already existing big.Int via a pointer, so no update
is needed.

7310e748e3 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.

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.
