81d89cd502 core: fix SystemFee calculation for Invocation TXes
They have it specified right in the transaction. Unfortunately, this little
change rendered invalid our RPC test chain, but I think it became even better
after it, especially given that chain generation is a nice test by itself, so
it should be running as a regular test.

ae6edf0601 core: add a check for fractional gas in invocation TXes

c258adb532 core: move spent coin management out of the inner storeBlock loop
prevHash == input.PrevHash, so make less DB accesses and more real work. Fix
some bugs along the way:
 * spentCoins structure may already be present in the DB when persisting TX,
   there is nothing wrong with that and we shouldn't overwrite it
 * it's only used for NEO and only to check for claim validity. Thus, when
   processing claim tx the corresponding spentCoins should always be present
   in the DB

36c6b6af14 core: put unspents get/put one loop above in storeBlock

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.

a4294f4b5f core: export UtilityTokenID and GoverningTokenID
Both are very useful outside of the core, this change also makes respective

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.

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.
