3e84f2bdf8 compiler: rewrite jump targets properly
Old implementation could view 0x62 byte in
a script as a JMP instruction irregardless of whether it is
a real opcode or a part of a parameter of another instruction.
In this commit instructions are decoded together with parameters
during jump label rewriting.

292051d8df core: get transactions from dao when mempool should not be used
All of these places deal strictly with the chain and shouldn't ever be
bothered with mempool. It also fixes a deadlock on reverification of
non-standard tx:

7ee8f9c5d8 network: fix networking stalls caused by stale peers
We can leak sending goroutines and stall broadcasts because of already gone

these can be seen in nodoka log along with (*Server).run blocking on
CMDGetAddr send):

9b03f968b1 core: fixe FreeGasLimit constraint
Lack of FreeGasLimit in privnet leads to gas limit exceeding in case of transactions with small amount of GAS to be used for invoke operation (< real cost of the transaction). Solution: Fixed constraint in case when FreeGasLimit == 0. So now we are able to perform transactions in privnet with FreeGasLimit = 0 for free.

1133bbe584 mempool: remove unverified transactions pool
Our mempool only contains valid verified transactions all the time, it never
has any unverified ones. Unverified pool made some sense for quick unverifying
after the new block acceptance (and gradual background reverification), but
reverification needs some non-trivial locking between blockchain and mempool
and internal mempool state locking (reverifying tx and moving it between
unverified and verified pools must be atomic). But our current reverification
is fast enough (and has all the appropriate locks), so bothering with
unverified pool makes little sense.

b675903f52 mempool/core: redesign mempool dances on block acceptance
We not only need to remove transactions stored in the block, but also
invalidate some potential double spends caused by these transactions. Usually
new block contains a substantial number of transactions from the pool, so it's
easier to make one pass over it only keeping valid items rather than remove
them one by one and make an additional pass to recheck inputs/witnesses.

794027a90b mempool: use one slice for both priorities
It doesn't harm as we have transactions naturally ordered by fee anyway and it
makes managing them a little easier. This also makes slices store item itself
instead of pointers to it which reduces the pressure on the memory subsystem.

325bea3fa9 mempool: cache Feer invocation results in the item
They shouldn't depend on the chain state and for the same transaction they
should always produce the same result. Thus, it makes no sense recalculating
them over and over again.
