* use the right variant in LightClientRootHash::from_bytes()
* make block.header.light_client_root_hash pub(super)
* add tests for LightClientRootHash and block.light_client_root_hash
The Heartwood upgrade changes the meaning of the hashFinalSaplingRoot to
hashLightClientRoot. Since we don't know the network upgrade heights in
zebra-chain, we just use [u8; 32] for now.
* Add MIN and MAX for BlockHeight and LockTime
* Remove duplicate test cases
* fix a comment about the minimum lock time
The minimum LockTime::Time is 5 November 1985 00:53:20 UTC, so the first
day that only contains valid times is 6 November 1985 (in all timezones).
Similarly, the maximum LockTime::Time is 7 February 2106 06::28::15 UTC,
so the last day that only contains valid times in all time zones is
5 February 2106.
* fix: Reject checkpoint lists with bad hashes or heights
Reject the all-zeroes hash, because it is the parent hash of the genesis
block, and should never appear in a checkpoint list.
Reject checkpoint heights that are greater than the maximum block
height.
* 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
* create hash submodule for block
* create header submodule for block
* create serialize submodule for block
* add newline to hash.rs (fmt)
* Update zebra-chain/src/block/tests.rs

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.
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.
