* Send the final checkpoint block to the checkpoint verifier
Also:
* route blocks with no height to the block verifier
* update an incorrect comment
* Add missing {
* rustfmt
* refactor block and tx validation errors
* rename errors module to error
* move NoTransactions to BlockError
* clarify some errors, use dbg format for hash in error
* mnake is_coinbase_first return BlockError
* add new error types for each consensus Service

Using a Buffer with size 1 is a footgun because it allows only one
sender to call poll_ready at a time. This is usually undesirable
because it means that a task or service that calls poll_ready but only
makes a service call later (potentially much later) will block all other
callers.
This makes the component verifiers both always return `poll_ready`,
because they do not exert backpressure and cannot fail.
The checkpoint verifier now immediately rejects any blocks that arrive
after it finishes checkpointing, instead of marking the service itself
as failed.
The chain verifier is agnostic to the readiness behavior of its
components, and reports readiness when they are both ready.
Instead of conditionally parsing the hardcoded checkpoint list and
optionally making a CheckpointVerifier, make one unconditionally, and
use the config settings to decide whether to route responses to it.
Then, fix up all of the places needed to make it compile and remove all
of the dead code.
This disables one test that can't be easily fixed at the moment, because
it tests the wrong thing: the checkpoint and block verifiers will
produce different transcripts.
It also disables the initial_tip logic for now, pending simplification
of the ChainVerifier logic.
* stop committing to the state in the ChainVerifier
* commit to the state in the BlockVerifier
* commit to the state in the CheckpointVerifier

* add CheckpointList::new_up_to(limit: NetworkUpgrade)
* if checkpoint_sync is false, limit checkpoints to Sapling
* update tests for CheckpointList and chain::init
This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.
Log a message with the height when we get duplicate blocks.
Downgrade some verifier errors and warnings to info and debug, because
some peers on mainnet consistently provide bad blocks.
