be avoided.

544f2c2cb2 core: use proper storage price within the whole interop context
We shouldn't use StoragePrice from Blockchain because its dao doesn't
contain the whole set of changes from previouse transactions in the
current block. Instead, we should use an updated storage price for
each transaction and retrieve the price from cached DAO.

91a4bc5beb core: use proper DAO to get ExecFeeFactor
The usage of the Blockchain's one leads to the same ExecFeeFactor within
a single block. What we need is to update ExecFeeFactor after each
transaction invocation, thus, cached DAO should be used as it contains
all relevant changes.

de2579ec07 dao: put contract IDs into keys using big endianness

f80680187e storage: expose private storage map for more efficient MPT batch
It couldn't be done previously with two maps and mixed storage, but now all of
the storage changes are located in a single map, so it's trivial to do exact
slice allocations and avoid string->[]byte conversions.

7dc8fc443f dao: simplify buffer management for private DAO
Private DAO is only used in a single thread which means we can safely reuse
key/data buffers most of the time and handle it all in DAO.

Doesn't affect any benchmarks.

9bfb3357f2 storage: add "private" mode to MemCachedStore
Most of the time we don't need locking on the higher-level stores and we drop
them after Persist, so that's what private MemCachedStore is for.

It doesn't improve things in any noticeable way, some ~1% can be observed in
neo-bench under various loads and even less than that in chain processing. But
it seems to be a bit better anyway (less allocations, less locks).

9d2ef775cf storage: simplify (*MemCachedStore).Put/Delete interface
They never return errors, so their interface should reflect that. This allows
to remove quite a lot of useless and never tested code.

Notice that Get still does return an error. It can be made not to do that, but
usually we need to differentiate between successful/unsuccessful accesses
anyway, so this doesn't help much.

54bc603831 core: remove old storage items synchronously during jump
There won't be a lot of them and GC experience we have shows that iterating

3a2b800e5f core: remove stale transfer entries, fix #2096
Initially I thought of doing it in the next persist cycle, but testing shows
that it needs just ~2-5% of the time MPT GC does, so doing it in the same
cycle doesn't affect anything.

ccdda21718 stateroot: add and use DataMPTAux for auxiliary data

height-stateroot mapping entries that our GC has to iterate over for no

423c7883b8 core: implement basic GC for value-based storage scheme
The key idea here is that even though we can't ensure MPT code won't make the
node active again we can order the changes made to the persistent store in
such a way that it practically doesn't matter. What happens is:
 * after persist if it's time to collect our garbage we do it synchronously
   right in the same thread working the underlying persistent store directly
 * all the other node code doesn't see much of it, it works with bc.dao or
   layers above it
 * if MPT doesn't find some stale deactivated node in the storage it's OK,
   it'll recreate it in bc.dao
 * if MPT finds it and activates it, it's OK too, bc.dao will store it
 * while GC is being performed nothing else changes the persistent store
 * all subsequent bc.dao persists only happen after the GC is completed which
   means that any changes to the (potentially) deleted nodes have a priority,
   it's OK for GC to delete something that'll be recreated with the next
   persist cycle

Otherwise it's a simple scheme with node status/last active height stored in
the value. Preliminary tests show that it works ~18% worse than the simple
KeepOnlyLatest scheme, but this seems to be the best result so far.

Fixes #2095.

c4ee310e85 mpt: modify refcounted storage scheme to make GC possible
Add "active" flag into the node data and make the remainder modal, for active
nodes it's a reference counter, for inactive ones the deactivation height is
stored.

Technically, refcounted chains storing just one trie don't need a flag, but
it's a bit simpler this way.

86cb4ed80f mpt: add the notion of MPT mode
