34646ddf51 [T4] Rename all shiftsize / cuckoo_size to edge_bits and change value for T4 (#1752)
* replace all size_shift / cuckoo_size by edge_bits and change some constants for T4
* replace remaining occurrences of sizeshift

Rust Cuckatoo for verifier and test-miner (#1558)
* cuck placeholder

* rustfmt

* cuckatoo, early days

* rustfmt

* data structures are in place, siphash key creation is consistent with @tromp

* solver in place, (not yet working)

* cuckatoo test solver working with test nonce

* rustfmt

* update solver to remove adjacency list removals

* verifier functioning

* rustfmt

* Proper error handing in Cuckatoo module, couple of tests

* modify cuckoo/cuckatoo solvers and verifiers to function identically, in advance of trait refactoring

* rustfmt

* refactor PoW context into trait, default to using cuckoo context

* rustfmt

* create macros for integer casting/unwraps

* don't instantiate structs when just verifying, add test validation vector for cuckatoo 29

* rustfmt

* don't init cuckoo structs if just validating

* test fix

* ensure BH hashing for POW is only done within miner/validators

Dual proof of work, first step (#1534)
* 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

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

Remove redundant hashing of header before proof of work (#1118)
We used to hash the hash of the header, needlessly. This also
makes a few function signatures more explicit.

Note that this is consensus breaking and should be accompanied
with a similar change on the cuckoo-pow repository:

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?
