[Distutils] packaging hooks for "pysetup3 remove projectXYZ"

[Vinay Sajip]

In general it is possible for an installation to make certain system changes
other than the record of files written during an installation (for example,
under Windows, there may be distribution-specific Windows registry updates).

There seems to be no hook that's called when a distribution is removed, which
would allow distribution-specific cleanup code to be called (e.g. to undo
Windows registry changes).

Such a hook should be provided, and I've created a ticket for this:

http://bugs.python.org/issue12416

I believe there should be a pre- and a post- hook, just as there is for
commands. Éric has suggested getting opinions from the mailing list, so what do
you all think about this?
