Cleanup

Just embed the logic needed right in to wallet implementations. This will cause a little bit of code duplication but avoids the complexity of the functor

Add a new signing method to sign_transaction so that it can call out to an external functor to sign the transaction's digest. We will not always have access to the private_key so transaction signing can't expect to use that.

cleanup of transaction_context, throwing soft resource limit exceptions if limit is due to block, and preferential network billing of prunable data (#2000)

* cpu_usage limit for an action is properly tracked even through inline actions
* receipt should store net usage in words
* total billed cpu usage for a transaction should be rounded up to nearest multiple of 1024
* enforce the cpu and net usage limits set in chain configuration
* additional stateless validation on generated transactions
* clear expired input transactions (and do not touch generated transactions) on start block rather than finalize block
* fix clear expired input transactions to use pending block time rather than head block time
* update producer authority at start of block (implemention still necessary)
* move resource limit updates and updating tapos from commit_block to finalize_block
* fix to controller::last_irreversible_block_id()
* reduce default_base_per_transaction_net_usage

fixed vulnerability in previous transaction_mroot definition by now also committing to region_id, cycle_index, shard_index, and trx_index in leaf nodes of Merkle tree #1972

Enforce region id in transaction header.

Removed old calculate_transaction_merkle_root function call from
block_tests/push_invalid_block and block_tests/block_id_sig_independent
since they weren't critical to the tests anyway.

Also, bill usage (most critically network bandwidth) for accepting delayed transaction into the block.

compress context_free_data in packed_transaction and change bandwidth usage values in transaction header into upper limits

Also, disallowed redundant signatures in a tx that are signed by the
same key.

Modified block_tests/irrelevant_sig_soft_check to check for multiple
signatures by same key and to account for the fact that blocks with
transactions that have irrelevant signatures are objectively invalid.

Also added block_tests/irrelevant_sig_hard_check unit test to verify
that such objectively invalid blocks are rejected.

This is a crude but functional key recovery cache for transactions. It improves performance considerably. Today it can grow forever but the next release will contain a proper implmentation.
