* allow selecting a commit while providing a key index
* added static reference to libsecp that can be called throughout
* don't serialise rangeproof to json if it's not desired
Moved the HTTP APIs away from the REST endpoint abstraction and
to simpler Hyper handlers. Re-established all routes as v1.
Changed wallet receiver port to 13415 to avoid a gap in port
numbers.
Finally, rustfmt seems to have ignored specific files arguments,
running on everything.
* adding more useful handlers
* added method to return last n leaf nodes inserted into the sum tree
* endpoints in place for getting last n sumtree nodes
* Fix for the chain pipeline partly relying on an outdated head,
leading to not properly recognizing a fork and inconsistent sum
tree state.
* Do not drop block requests during sync that don't get satisfied,
retry enough time to get them and avoid stall.
* Always validate header, even in sync where we may have validated
it already. We don't want a block coming from a peer that could
squeeze through with an invalid header.
* When syncing, do not mark blocks that were errored by the chain
as received (typical case: orphan). Keep retrying.
* Improved chain state dump for debugging.
* Do not add to orphans blocks too far in the future.
* Better error reporting on db errors.
* Related sync test fixes.
TODO figure out why syncing peers timeout so often, very useful
to test but not that great for a fast sync experience.
* Adding switch commit to grin outputs
* logging output fix
* adding switch commitment hash to sum tree node
* added hash_with to Hashed trait, to allow for hashing to include another writeable element
* adding hash_with as method in hashed trait
* added global slog instance, changed all logging macro formats to include logger instance
* adding configuration to logging, allowing for multiple log outputs
* updates to test, changes to build docs
* rustfmt
* moving logging functions into util crate
* Integrate PMMR and its persistent backend with the Chain
* Chain can set tree roots; PMMR backend discard
* Check spent and prune for each input in new block
* Handling of forks by rewinding the state
* More PMMR tests and fixes, mostly around rewind
* Rewrite get_unspent to use the sumtrees, fix remaining compilation issues
