Align crate versions and user-agent with NU numbers.
...
We had a brief discussion on discord and it seemed like we had consensus on the
following versioning policy:
* zebrad: match major version to NU version, so we will start by releasing
zebrad 3.0.0;
* zebra-* libraries: start by matching zebrad's version, then increment major
versions of each library as we need to make breaking changes (potentially
faster than the zebrad version, always respecting semver but making no
guarantees about the longevity of major releases).
This commit sets all of the crate versions to 3.0.0-alpha.0 -- the -alpha.0
marks it as a prerelease not subject to perfect adherence to compatibility
guarantees.

Check for bad heights or hashes in checkpoint lists ( #639 )
...
* 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.

The maximum block size is 2,000,000 bytes. This commit also limits the

The proptests might test the maximum block size, but they are
