357b675090 core: don't choose duplicating standby validators
We may already have chosen some of standby validators, so don't repeat.

f9c6a0d77c core: make voting choose the best validators
They need to be sorted in order for voting system to work.

2ff7ceb8cf core: properly update validator votes for Account descriptor
ValidatorsCount is not implemented yet, but we need to update validators
properly, adding account's vote to their votes count.

807309a0de core/state: only drop unregistered non-voted validators
Simple as that: UnregisteredAndHasNoVotes != !RegisteredAndHasVotes

Registered validators should stay in the DB, we might be in the process of
updating votes for them and that starts with subtraction.

32a064aa31 keys: add Cmp method to PublicKey
It can be used by code that doesn't operate with PublicKeys, but still needs
to be able to compare keys for some purposes.

38d0efc96c core: fix Registered state descriptor processing
It has simple boolean value encoded, no `strconv` needed (it actually chokes
on such input).

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:

We can leak sending goroutines and stall broadcasts because of already gone
peers that happened to be cached by some s.Peers() user (more than 800 of
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.
