[OpenAFS] Perl AFS module with OpenAFS 1.4.7

[Russ Allbery]

I vaguely recall there was a mailing list message reporting problems with
the AFS Perl module with current versions of OpenAFS, but I can't find it
again now.  I was refreshing my x86 Debian packages and had to make a few
minor fixes for the com_err renaming, but nothing seems horribly broken.
With the below patch applied (and the KAS test disabled, since we have no
kaserver), the module passes all of its tests.  I haven't used it to do
anything beyond that, though.

For some reason, the XS version checking was failing miserably with Perl
5.10 (complaining about undefined variables), so I had to disable it.  I'm
not sure what's up with that; I haven't investigated further.

A better fix than this one is probably to rename all of the com_err calls
to use the afs_* names, but this was expedient and I wasn't sure if any of
the other symbols were used.
