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:
