Bugzilla

I also removed the `Version` class that inherited from `LooseVersion` in
`configure/util.py`. The resulting difference is that 'patch' is no
longer an available attribute, it is now called 'micro'. I did this for
the sake of consistency (Everything following the same naming convention
found in `packaging.version.Version`).

In `packaging.version` there is also a `LegacyVersion` which is less
strict, similar to `LooseVersion`. I chose not to use this at all since
it is already deprecated and is slated for removal. Comparing a
`LegacyVersion` against a `Version` always results in the
`LegacyVersion` object being `less`, which is not intuitive and can
cause unexpected behavior.

All "versions" should now be Version objects and they can no longer be
compared against hard-coded strings. As such, all hard-coded are also
constructed into Version objects so that they can be compared..
