* Reverse displayed endianness of transaction and block hashes
* fix zebra-checkpoints utility for new hash order
* Stop using "zebrad revhex" in zebrad-hash-lookup
* Rebuild checkpoint lists in new hash order
This change also adds additional checkpoints to the end of each list.
* Replace TransactionHash with transaction::Hash
This change should have been made in #905, but we missed Debug impls
and some docs.

* Move to RFC number 5
* rfc: add PR link to state update RFC
* rfc: change state RFC to store blocks by height.
The rationale for this change is described in the document: it means
that we write blocks only to one end of the Sled tree, and hopefully
helps us with spatial access patterns.
This should help alleviate a major cause of memory use in Zebra's
current WIP Sled structure, which is that:
- blocks are stored in random, sparse order (by hash) in the B-tree;
- the `Request::GetDepth` method opens the entire block store and
queries a random part of its block data to determine whether a hash is
present;
- if present, it deserializes the complete block data of both the given
block and the current tip block, to compute the difference in block
heights.
This access pattern forces a large amount of B-tree data to remain
resident, and could probably be avoided if we didn't do that.
* rfc: add sprout and sapling anchors to sled trees.

* rfc: fill in details of state service requests.
* rfc: extract commit process from API description
* rfc: add anchor parameters to CommitBlock.
These have to be computed by a verifier, so passing them as parameters
means we don't recompute them.
