9571ecffac core: add proper asset issuer for UTXO assets 
It just wasn't set which is wrong (AFmseVrdL9f9oyCzZefL9tG6UbvhPbdYzM was
always the issuer).

4a8259caea rpc: adjust getrawtransaction and gettransactionheight RPC call 
We should not return transaction metadata from `getrawtransaction` in case
transaction is not in the mempool. Height shouldn't be returned from
`gettransactionheight` in case transaction is in the mempool.

d3e415d3bd core/state: reverse the order of ForEachTransfer 
When using limits we're usually concerned about the most recent
transfers. Returning 3 transfers from the middle of the chain isn't very
helpful.

Becomes this transfer:

Something is wrong here.

6d32751292 core: fix stateroot height update for testnet 
When synchronizing with stateroot-enabled network from genesis and if
stateroot is not enabled in block zero we were failing to update state height
because initially it's updated with a jump from 0 to StateRootEnableIndex, so
we should allow that to happen to have correct state height.

a1c4d7ce26 core: do MPT compaction every once in a while 
We need to compact our in-memory MPT from time to time, otherwise it quickly
fills up all available memory. This raises two obvious quesions --- when to do
that and to what level do that.

As for 'when', I think it's quite easy to use our regular persistence interval
as an anchor (and it also frees up some memory), but we can't do that in the
persistence routine itself because of synchronization issues (adding some
synchronization primitives would add some cost that I'd also like to avoid),
so do it indirectly by comparing persisted and current height in `storeBlock`.

Choosing proper level is another problem, but if we're to roughly estimate one
full branch node to use 1K of memory (usually it's way less than that) then we
can easily store 1K of these nodes and that gives us a depth of 10 for our
trie.

69ccca675d core: fix PrevHash calculation for MPTRoot 
This was differing from C# notion of PrevHash. It's not a previous root, but
rather a hash of the previous serialized MPTRoot structure (that is to be
signed by CNs).

b96fe8173c core,dao: implement Block-level storage caching 
The order in which storage.Find items are returns depends on what items
were processed in previous transactions of the same block.
The easiest way to implement this sort of caching is to cache operations
with storage, flushing the only in `Persist()`.

9454ef5c28 core: improve locking in storeBlock 
Getting batch, updating Prometheus metrics and pushing events doesn't require
any locking: batch is a local cache batch that no one outside cares about,
Prometheus metrics are not critical to be in perfect sync and events are
asynchronous anyway.
