39d2e9e0cb Make some globals static that can be 
External linkage does not help and just encourages sloppy dependencies
and can lead to weird issues when there are name collisions.

cd9d373987 Auto merge of #1260 - str4d:1175-byte-array-manipulation, r=ebfull 
Update Equihash implementation to match the Zcash spec

5be6abbf84 Store the Equihash solution in minimal representation in the block header 
The genesis blocks and miner tests have been regenerated, because changing the
block header serialisation format changes the block hash, and thus validity.

The Equihash solutions have been removed from the bloom test inputs for
simplicity (block validity is not checked there; only a valid serialisation is
necessary).

caa0348f04 Update Equihash hash generation to match the Zcash spec 
Changes:

- floor(512/n)*n/8 bytes of BLAKE2b output is split between floor(512/n)
  adjacent indices, instead of using one hash call per index.

- Parameters with n/(k+1) mod 8 != 0 will expand the BLAKE2b output to byte
  boundaries for colliding, instead of using a longer output and clearing bits.

- The genesis blocks have been regenerated.

- The test vectors have been regenerated.

- The Equihash inputs for the cancellation tests were modified to ensure that
  valid solutions were available to exercise the full solver.

881ffbfc87 Add methods for byte array expansion and compression 
These methods convert between:

- A byte array of length NL/8, and
- An array of N blocks of ceil(L/8) bytes.

Eliminate some of the duplicates caused by truncating indices

036dcbd94a Remove the assumption that n/(k+1) is a multiple of 8. 
This version works, but generates the initial rows in a way that is not what we
want to specify. See #1175 for resolving this.

3c654f38eb Eliminate probably duplicates in final round

included.

0a66f01304 Use depth-first scan for eliminating partial solutions instead of breadth-first 
This reduces the peak number of lists in-memory from 2^k to k, and enables the
solver to eliminate most duplicates before it has instantiated the full set of
leaves.
