* header MMR in use within txhashset itself
works with fast sync
not yet in place for initial header sync

* merge from upstream and fix server test
* rustfmt
* rustfmt
* merge from master
* update latest libsecp merge
* fix commitment to zero value generation
* Move Proof and Difficulty types to pow module. Difficulty scaling calculation.
* Diffculty scaling and size shift for 2nd PoW
* Backport e7eb26ee
* Test compilation fixes
* Scaling only need to go one way, as @tromp pointed out
* simplify tx validation and aggregation
we *only* need to account for reward when building a block from txs
* rustfmt
* cleanup and tests passing
* rustfmt
* better comments in with_reward()
* fix wallet tests
* Include commitments non-duplicate checks in aggregate
* Remove said check from the pool
* Block building now uses tx aggregation to reduce duplication
* add new core mmr routine upon which others should be built more efficiently
* tons of pmmr optimizations and simplifications
* fix typo and extend docs
* change initial spaces to tab to fix indentation
* improve: time crate flagged as deprecated, switch to actively maintained chrono crate
* improve: complete the switching from deprecated time crate to chrono crate, for all the tests part
* improve: complete switching to chrono crate, for the left tests in 'chain' and 'wallet'
* fix misbehaving simulnet fastsync test
cleanup redundant cutoff vs bitmap params is rewind and check_compact
* make sure we do not verify full kernel history on a writeable txhashset extension
rework simulnet simulate_fast_sync test to be more robust
* fixup store tests
* sleep for a bit longer to give nodes time to update
their sync_state correctly
* tweak timing of simulate_block_propagation
* Handle SIGINT and SIGTERM (#1180)
* Handle SIGINT and SIGTERM
* pin croaring to version 0.3.2 until we get the clang conflict sorted out (#1183)
* document proposals for - (#1190)
* conditional timelocked outputs, and
* conditional relative timelocked outputs
* problem with validation on rewind
* update difficulty scenarios to display much more data
* correct average sum output
* update pre-genesis block padding to just use previous block's data
* Added sizeshift to proof of work and encoding as VLQ
* Fix some loose ends to get things to compile
* Rename sizehift to min_sizeshift
* Pipeline checks for PoW Cuckoo Cycle size shift and adjustment
factor before difficulty comparison.
* Working delta+VLQ encoding of u64 PoW, unfortunately still a
little larger than u32, at least for Cuckoo30.
* Changed binary encoding of proof of work to a sequence of exact
compact bit representation of each nonce. Somewhat simpler,
shorter and matches the data to be hashed.
* Few fixes based on @tromp feedback:
* Max nonce is 2^(N-1)
* Need a separate constant for reference sizeshift
* Cuckoo implementation now conserves sizeshift. Test providing a
block at higher sizeshift.
* Last small overflow protection
* implement prune_list as a bitmap
and simplify
* cleanup prune_list, use maximum()
* handle migration of prune_list to new bitmap prun file
* legacy filename consts
* cleanup and docs
* Add kernel commitments sum and kernel and output MMR sizes to block header
* Sum a block without including previous sums, cleanup. Blocks are now summed and validated based on their own totals and not the totals since genesis. This allows to get rid of BlockSum and simplified the setting of a new block's roots, kernel sum and MMR sizes. Fixes#116
* Additional kernel MMR validation to check all prior header roots successively
* Wallet tests fix
