...
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.

chain: Check the maximum block size when parsing
...
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.)
