65503aa9b4 core: add nonce field to transaction
1. Closes #840: added Nonce field to transaction.Transaction and
removed Nonce field from transaction.MinerTx

2. Added following methods to different tx types:
  - NewMinerTx()
  - NewMinerTxWithNonce(...)
  - NewEnrollmentTx(...)
  - NewIssueTx()
  - NewPublishTx(...)
  - NewRegisterTx(...)
  - NewStateTx(...)
in order to avoid code duplication when new transaction is created.

3. Commented out test cases where binary transaction/block are used.
These test cases marked with `TODO NEO3.0: Update binary` and need to be
updated.

4. Updated other tests

5. Added constant Nonce to GoveringTockenTx, UtilityTokenTx and genesis
block to avoid data variability. Also marked with TODO.

ec76a0bf15 mempool: disallow more than one issue tx at once
Technically they could conflict for available asset amount, but as they're
very rare (and even can be considered obsolete) we can simplify this check.

claiming.

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.

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.

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.

a928ad9cfa mempool: make item an internal thing of mempool package
Nobody outside should care about these details, mempool operates on
transactions and that's it.

70b3839fd0 core/mempool: fix AddBlock and tx pooling concurrency issues
Eliminate races between tx checks and adding them to the mempool, ensure the
chain doesn't change while we're working with the new tx. Ensure only one
block addition attempt could be in progress.
