Verify script via bitcoinconsensus (paritytech#24)

* Minor pure refactor

* Replace tx_serialize_size_no_witness() with tx.base_size()

This function is already equivalently implemented in rust-bitcoin.

* Replace block_serialize_size_no_witness() with block.base_size()

* Use block.weight() and tx.weight()

* Separate out tx_verify module

* Rename header_verifier.rs to header_verify.rs

* Inline verify_transaction clsoure

* Verify script using bitcoinconsensus

* Fix difficulty bits check

* Double the stall timeout when the chain is higher than 300000
