Cuckatoo size shift upgrade schedule (#2024)
* 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

7dee490962 Two year secondary pow ratio fix (#2037)
* Tweak (consensus breaking) secondary_pow_ratio
* Look at chain type for sec pow ratio calc (hardfork is t4 only)

Cuckaroo Testnet4 hard fork (#1997)
* 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

refactor the state_sync to handle the long fork (#1902)
* 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

Accept multiple Cuckoo graph sizes (#1193)
* 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

2fa32d15ce Rustify core/src/core (#1122)
Small refactoring of one folder, if it makes sense I could extend the scope.
* Remove some cloning (real and just verbosity in the code)
* Naming conventions like to/into*
* Some Clippy's suggestions

I found that we don't use field init shorthand syntax, so I didn't touch this part, was it discussed before?

1bad7188b7 Fix Readable impl for Transaction (#795)
Fuzz test demonstrated that the current implemenation panics on reading from the network when serialized tx. Contains for example huge number of input or outputs. It allows a mailicious sender
to kill the server.
