* replace header_by_height index with reads into the header MMR
* rustfmt
* cleanup
* cleanup chain tests
* fix locate_headers to stop on our max header
* fix the deadlock in comact_blocks_db...
* cleanup and docs/comments
* Cuckatoo size shift upgrade schedule
* Move the schedule into graph_weight instead of messing with min edge bits
* Cleanup and fixes now that we have an agreed upon schedule
* refactor header MMR to use regular backend
this lets us store header hashes in the mmr data file
the hashes in the hash file are "hash with index"
* rustfmt
* get_header_hash(pos) on header extension
* rustfmt
* cleanup
* cleanup
* comments
* cleanup
* fixup testelem so tests work
* PoW context is now properly picked depending on the chain type,
edge bits and block height. Height const for T4 hard fork leaving
a couple weeks to have miners in place. Removed now unused Cuckoo context.
* Simplified block siphash
* Fix servers crate compilation
* Tiny bit cleaner block siphash. Maybe.
* Cuckatoo min edge bits update for T4 and mainnet
* Fix header size tests, Cuckatoo31 default means one more bit per edge
* Remove redundant param from verify_size
* block_accepted via adapter is now reorg aware
we skip reconciling the txpool is block is not most work
we skip reconciling the reorg_cache is not a reorg
* rustfmt
* logging tweaks
* rework block_accepted interface
* rustfmt
* rework reorg determination
* introduce BlockStatus to represent next vs reorg vs fork
* rustfmt
* cleanup logging
* log from adapter, even during sync
* split horizon into two explicit values for cut through and txhashset request
* let node which has 2-7 days of history be able to handle forks larger than 2 days
* add test simulate_long_fork
* add pause/resume feature on p2p for tests
* refactor the state_sync
* ignore the test case simulate_long_fork for normal Travis-CI
* refactor function check_txhashset_needed to be shared with body_sync
* fix: state TxHashsetDone should allow header sync
* cleanup pmmrable and len()
introduce FixedLength trait with a const LEN
make Hash impl FixedLength for consistency
* rustfmt
* store tests cleanup
* rustfmt
* whats going on with those comments and rustfmt?
* be careful resetting sync_head
make sure we have the header corresponding to header_head
and that nothing is corrupted from an earlier shutdown
* add logging when resetting heads due to missing header
* Update secp dependency to use crates.io version
* Add more details to various Cargo.toml
* Remove use of env variables that aren't reliably provided by cargo
* Replace logging backend to flexi-logger and add log rotation
* Changed flexi_logger to log4rs
* Disable logging level filtering in Root logger
* Support different logging levels for file and stdout
* Don't log messages from modules other than Grin-related
* Fix formatting
* Place backed up compressed log copies into log file directory
* Increase default log file size to 16 MiB
* Add comment to config file on log_max_size option
* header MMR in use within txhashset itself
works with fast sync
not yet in place for initial header sync
* add the (currently unused) sync_head mmr
* use sync MMR during fast sync
rebuild header MMR after we validate full txhashset after download
* support missing header MMR (rebuild as necessary) for legacy nodes
* rename to HashOnly
* cleanup backend.append()
* simplify vec_backend to match simpler append api

* simply pmmr append api
no need to pass position when appending

* cleanup
* First pass at secondary proof of work difficulty adjustments
* Core and chain test fixes
* Next difficulty calc now needs a height. Scaling calculation fixes. Setting scaling on mined block.
* Change factor to u32 instead of u64.
* Cleanup structs used by next_difficulty
* Fix header size calc with u32 scaling
