dcda7bec63 core: squash PS-seeking and merging routines in (*MemCachedStore).Seek
We don't need a separate routine to merge seek results.

f2ac07a3c0 core: do not copy key/value results got from MemCachedStore.Seek
They are already copied inside the MemCachedStore.Seek, so that

7ba88e98e2 core: optimize (*MemCachedStore).Seek operation
Real persistent storage guarantees that result of Seek is sorted
by keys. The idea of optimisation is to merge two sorted seek
results into one (memStore+persistentStore), so that
(*MemCachedStore).Seek will return sorted list. The only thing
that remains is to sort items got from (*MemoryStore).Seek.

191cc45032 core: sort items in MemoryStore.Seek
MemoryStore is used in a MemCachedStore as a persistent layer in tests.
Further commits suppose that persistent storage returns sorted values
from Seek, so sort the result of MemoryStore.Seek.

Benchmark results for 10000 matching items in MemoryStore compared to
master:
name          old time/op    new time/op    delta
MemorySeek-8     712µs ± 0%    3850µs ± 0%   +440.52%  (p=0.000 n=8+8)

name          old alloc/op   new alloc/op   delta
MemorySeek-8     160kB ± 0%    2724kB ± 0%  +1602.61%  (p=0.000 n=10+8)

MemorySeek-8     10.0k ± 0%     10.0k ± 0%     +0.24%  (p=0.000 n=10+10)

0bc81aecf4 compiler: do not emit code for unused imported functions
Our current algorithm marks function as used if it is called
at least ones, even if the callee function is itself unused.
This commit implements more clever traversal to collect usage
information more precisely.

8e7c76827b core: optimise (*Billet).Traverse and (*Trie).Find
(*Billet).Traverse changes:
1. Get rid of the `offset` argument. We can cut `from` and pass just the
part that remains. This implies that node with path matching `from` will
also be included in the result, so additional check needs to be added to
the callback function.
2. Pass `path` and `from` without search prefix. Append prefix to the
result inside the callback.
3. Remove duplicating code.

(*Trie).Find changes:
1. Properly prepare `from` argument for traversing function. It closly
depends on the `path` argument.

c009356b73 core: simplify component flushing in storeBlock
Instead of flushing everything to `cache` and then to `bc.dao`, wrap `bc.dao`
directly for block/tx data and AERs and then flush to it. Block/transactions
are usually processed more quickly than other components, so they easily end
up in `cache` where they directly affect Seek performance for any executing
transaction.

Simple as it is this change improves voter NEO transfer benchmark with 1000
accounts by more than 25%, from ~18500 TPS to ~23500 TPS. It doesn't affect
much other cases.

b66bc33cf9 native: short-circuit successive GAS distributions
GAS can only be distributed once in a block for particular address, so it
makes little sense trying to calculate it again and again. This fixes
neo-bench for NEO voter, because without it we get ~2500 TPS for
single-address test and with it it jumps 13-fold to normal values like
~33500.

c113d682bd core: fix NEO balance state handler
We need to store NEO balance's LastUpdateHeight before GAS mint,
because mint can call onNEP17Payment and onNEP17Payment can call NEO
transfer which also calls GAS mint. Storing balance height allows to
avoid recursion.
