a903147b60 keys: rename Signature to GetScriptHash, make it return Uint160
Signature itself wasn't used at all and its name is very misleading, Uint160
script hash is way more useful.

eb11e5fb11 core: implement basic policying support, fix #370
Implement mempool and consensus block creation policies, almost the same as
SimplePolicy plugin for C# node provides with two caveats:
 * HighPriorityTxType is not configured and hardcoded to ClaimType
 * BlockedAccounts are not supported

Other than that it allows us to run successfuly as testnet CN, previously our
proposals were rejected because we were proposing blocks with oversized
transactions (that are rejected by PoolTx() now).

Mainnet and testnet configuration files are updated accordingly, but privnet
is left as is with no limits.

Configuration is currently attached to the Blockchain and so is the code that
does policying, it may be moved somewhere in the future, but it works for
now.

22f5667530 mempool: return fee along with tx when requesting tx
Users of GetVerifiedTransactions() don't want to recalculate tx fee and it's
nice to have it returned from TryGetValue() also sometimes.

a4294f4b5f core: export UtilityTokenID and GoverningTokenID
Both are very useful outside of the core, this change also makes respective
transactions initialize with the package as they don't depend on any kind of
input and it makes no sense recreating them again and again on every use.

b41a5239c6 core: always sort the result of GetValidators
It wasn't sorted when all validators were elected. There is also no need to do
`Unique()` on the result because validators are distinguished by the key, so
no two registered validators can have the same key.

As C# node does it. Technically it's only needed for consensus and could be

The problem is that the select in putPacketIntoQueue() only works the way it
was intended to after the `close(p.done)`, but that happens only after
successful unregistration request send. Thus, do disconnects the other way
around, first unblock queueing and exit goroutines, then destroy the
connection (if it wasn't previously destroyed) and only after that signal to
the Server.

c8a248596e core: introduce ValidatorsCount, make a proper count
We were completely lacking ValidatorsCount that is supposed to track the
number of votes with particular count of consensus nodes which in theory can
change the number of active consensus nodes (if it ever to exceed the number
of standby validators), so we were not producing the right count and based on
that not giving the right set of validators.

Fixes #512.
