Import XML-Catalog-v1.0.1 as textproc/p5-XML-Catalog.

Catalogs may be written in either SOCAT or XML syntax (see the proposal
for syntax details); XML::Catalog will assume SOCAT syntax if the catalog
is not in well-formed XML syntax.

TODO: libixion support (once it is added to pkgsrc)
Fix build of db{4,46,5} on MirBSD.

The build does not create all those unnecessary shlib symlinks on MirBSD
(I believe this is due to a patch I sent in years ago), so add separate
PLIST.MirBSD files that do not contain these files.

(BTW, I would be grateful to learn how I can achieve the same effect
without copying PLISTs, but this works.)
