hash (features|commitment) in output mmr (#615)
* experiment with lock_heights on outputs

* playing around with lock_height as part of the switch commitment hash

* cleanup

* include features in the switch commit hash key

* commit

* rebase off master

* commit

* cleanup

* missing docs

* rework coinbase maturity test to build valid tx

* pool and chain tests passing (inputs have switch commitments)

* commit

* cleanup

* check inputs spending coinbase outputs have valid lock_heights

* wip - got it building (tests still failing)

* use zero key for non coinbase switch commit hash

* fees and height wrong order...

* send output lock_height over to wallet via api

* no more header by height index
workaround this for wallet refresh and wallet restore

* refresh heights for unspent wallet outputs where missing

* TODO - might be slow?

* simplify - do not pass around lock_height for non coinbase outputs

* commit

* fix tests after merge

* build input vs coinbase_input
switch commit hash key encodes lock_height
cleanup output by commit index (currently broken...)

* is_unspent and get_unspent cleanup - we have no outputs, only switch_commit_hashes

* separate concept of utxo vs output in the api
utxos come from the sumtrees (and only the sumtrees, limited info)
outputs come from blocks (and we need to look them up via block height)

* cleanup

* better api support for block outputs with range proofs

* basic wallet operations appear to work
restore is not working fully
refresh refreshes heights correctly (at least appears to)

* wallet refresh and wallet restore appear to be working now

* fix core tests

* fix some mine_simple_chain tests

* fixup chain tests

* rework so pool tests pass

* wallet restore now safely habndles duplicate commitments (reused wallet keys)
for coinbase outputs where lock_height is _very_ important

* wip

* validate_coinbase_maturity
got things building
tests are failing

* lite vs full versions of is_unspent

* builds and working locally
zero-conf - what to do here?

* handle zero-conf edge case (use latest block)

* introduce OutputIdentifier, avoid leaking SumCommit everywhere

* fix the bad merge

* pool verifies coinbase maturity via is_matured
this uses sumtree in a consistent way

* cleanup

* add docs, cleanup build warnings

* fix core tests

* fix chain tests

* fix pool tests

* cleanup debug logging that we no longer need

* make out_block optional on an input (only care about it for spending coinbase outputs)

* cleanup

* bump the build

cc9ec53390 sync_head port from testnet1 (#425)
* port simple_sync across from testnet1, sync head & improved fork handling
* introduce new sync_head for tracking header chain during sync
* add debug logging in body_sync for state of various heads
* update header_head during sync if header is now the one with most work, pass in sync and head contexts to pipe
* port across sync_head changes from master, put the 1s sleep back in...
* let sync run even if the full 512 headers are all known, give sync a chance to sync against a fork that forked a long time ago
* handle height jumping during a reorg
block validaton should not check for height+1 based on head
no assumptions should be made about height indices
* quick(er) check for previous block in process_block (we cannot check height against ctx head)
* make body_sync a _lot_ faster by finding the forked block more efficiently...
* fix monitoring peers log msg
* fix chain tests
* fix grin tests - we were using the wrong genesis hash (wrong chain type)
* apparently needs setting in both places...
* body -> header -> sync (#414)
* port over body -> header -> sync changes from testnet1

Cleanup HTTP APIs, update ports to avoid gap, rustfmt
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.

New Chain struct acting as facade for all chain operations
Introduce a new Chain struct that maintains the current head,
acts as facade to the store and the block processing pipeline
and handles all appropriate locking.

All higher level components, like the overall server, REST APIs
and miner have been update to only depend on Chain. Cleaned up
some duplication and tests now that there's a single entry point
to all blockchain operations.

Apply new difficulty algo, remove configurable cuckoo size
Integrate the new difficulty calculation into the block chain
validation, the miner and tests. As the difficulty calculation
doesn't use varying Cuckoo sizes anymore and we narrowed down
reasonable final Cuckoo Cycle parameters, removed all Cuckoo
Cycle sizes from block headers.

Formalized easier Cuckoo Cycle sizes for testing (and possibly
testnet) by introducing a test mode in configuration. Updated
all tests.

Sending end of the wallet
Most of the logic to build a transaction that sends coin to
another party. Still requires more debugging and clean up.
Main changes and additions are:

* Update to serde 1.0
* API endpoint to retrieve an Output
* Output is now Serialize and Deserialize
* Wallet configuration
* Command line for the send operation
* Wallet data checker to update created outputs into confirmed
* Wallet-specific configuration

Fixes for chain processing during bootstrap
Adds checks to ignore a block that's already known (can happen
if the block was saved but the chain update failed). Also saves
saves the chain slightly differently during bootstrap as the
header chain should only be updated when a header is received
(and not when we got a full block). Finally, do not broadcast
during bootstrap.

Save outputs under their own keys
Save outputs in every new block under their own hash. Done in the
same batch as the block. Allows for direct output lookups by hash
required by the p2p layer. Also store an index of output
commitment to output hash for wallet and input lookups.

Chain logic to support multiple forks, select the most worked fork as the head. Significantly simplified from the original direction as it doesn't seem that explicitly materializing forks is necessary.
