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).

net: correctly initialize nMinPingUsecTime

`nMinPingUsecTime` was left uninitialized in CNode.
The correct initialization for a minimum-until-now is int64_t's max value, so initialize it to that.

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.

Improve speed and accuracy of zcbenchmark validatelargetx
The verification test, in a loop, passes `spending_tx` (a `CMutableTransaction`) to the constructor of `MutableTransactionSignatureChecker`, which immediately uses it to create a non-mutable `CTransaction` object, which is used for the actual verification process.
Since `spending_tx` is not mutated during the verification loop & process, we can instead convert it to a `CTransaction` just once, and use it with `TransactionSignatureChecker`.
This removes the time to create `CTransaction` objects from the benchmark itself.
Results show an improvement in running time to complete the verification phase of the test and consistent times across z7 and z8 releases.
```
