* add proptests for invalid forms of input
* apply proptests to each valid block we have
* start moving equihash logic to BlockHeader
* provide an error based interface
* cleanup logging in dependent crate
* use is_equihash_solution_valid everywhere
* switch to proper equihash crate branch
* add block size limit test
* calculate max_transactions_in_block and max_inputs_in_tx
* abstract block generation
* move all test vectors to zebra-test
This change brings in the `equihash` crate from librustzcash and uses it to add a basic `is_valid` test for `EquihashSolutions`.

Use MAX constants for the block header version and time arbitrary test
ranges. Reduces the block header time arbitrary test range from 2**32 to
2**32-1 (u32::MAX). (2**32 is an invalid time value, which gets
truncated to 0 during serialization.)
Also add some comments about DateTime conversions.
Part of #477.
consensus: Add a checkpoint verifier stub
This stub only verifies blocks whose hashes are in the checkpoint
list.
It doesn't have tests, chain child verifies to their ancestors, or
support checkpoint maximum height queries.
Part of #429.
The maximum block size is 2,000,000 bytes. This commit also limits the
maximum transaction size in parsed blocks. (See #484 for the
corresponding limit on mempool transactions.)
The proptests might test the maximum block size, but they are
randomised. So we also want to explicitly test large block sizes.
(See #482 for these test cases and tests.)
Part of #477.
Verify the value of the equihash solution size field in block headers.
This field isn't stored in the BlockHeader struct, so we need to verify
it at parse time.
Part of #477.
