* do not treat txhashset.zip download as abusive behavior
* count times, not bytes so we exclude quiet increments
* use inc_quiet when tracking sent bytes via an attachment
* add comment
* fixup "quiet" counter entries
* rustfmt
* use FixedLength to define serialized size in bytes of various structs
replace usages of mem::size_of() with ::LEN so we correctly calculate serialized sizes in bytes
* rustfmt
* 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
* deserialize capabilities dropping unknown flag bits
* add tests for capabilities deserialization
* rustfmt
* FULL_NODE needs to be handled safely for legacy nodes
Fuzz test found that we don't read IPV6 addr (as part of p2p message)
properly. The code is supposed to read 8 dwords, but [0..8] is not a
slice of 8 ints, but a slice of one Range, so we always read just one
dword
* 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
* Initial expired peers removal
* Stop expired peers
* Simplify peer removal and remove only Defunct peers
* Make seed to check for expired peers every hour
* Get rid of unused vector of peers to remove
* Make peer deletion predicate closure immutable
* 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
* Add peers used bandwidth calculation and display in TUI
* Fix formatting
* Change Mutex to RwLock from peer's used bandwidth statistics in Tracker
* Make used bandwidth column in TUI peers list sort by sum of bytes
* 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
* fix: avoid a confusing log when fastsync start (#1720)
(cherry picked from commit 4f462cdfdc)
* small speed optimization for header sync (#1719)
(cherry picked from commit d3589d1bf5)
