* Implementation of Verifier, Scoring and Ready.

* Queue in progress.

* TransactionPool.

* Prepare for txpool release.

* Miner refactor [WiP]

* WiP reworking miner.

* Make it compile.

* Add some docs.

* Split blockchain access to a separate file.

* Make ethcore and ethcore-miner compile again.

* Make RPC compile again.

* Bunch of txpool tests.

* Migrate transaction queue tests.

* Nonce Cap

* Nonce cap cache and tests.

* Remove stale future transactions from the queue.

* Optimize scoring and write some tests.

* Simple penalization.

* Clean up and support for different scoring algorithms.

* Add CLI parameters for the new queue.

* Remove banning queue.

* Disable debug build.

* Change per_sender limit to be 1% instead of 5%

* Avoid cloning when propagating transactions.

* Add more traces, fix disabling miner.

* Fix creating pending blocks twice on AuRa authorities.

* Fix tests.

* re-use pending blocks in AuRa

* Use reseal_min_period to prevent too frequent update_sealing.

//! Transaction Readiness indicator
//!
//! Transaction readiness is responsible for indicating if
//! particular transaction can be included in the block.
//!
//! Regular transactions are ready iff the current state nonce
//! (obtained from `NonceClient`) equals to the transaction nonce.
//!
//! Let's define `S = state nonce`. Transactions are processed
//! in order, so we first include transaction with nonce `S`,
//! but then we are able to include the one with `S + 1` nonce.
//! So bear in mind that transactions can be included in chains
//! and their readiness is dependent on previous transactions from
//! the same sender.
//!
//! There are three possible outcomes:
//! - The transaction is old (stalled; state nonce > transaction nonce)
//! - The transaction is ready (current; state nonce == transaction nonce)
//! - The transaction is not ready yet (future; state nonce < transaction nonce)
//!
//! NOTE The transactions are always checked for readines in order they are stored within the queue.
//! First `Readiness::Future` response also causes all subsequent transactions from the same sender
//! to be marked as `Future`.
