 *shrug*, I'm not sure why we'd want to add support for lzma on the
obsolete .xml files. Smart and apt both support .sqlite now, and if
zypper doesn't they can always use modifyrepo to add them for SuSE.
 Also calling them "primary_db.xz" would fit the convention with
"groups.gz".

 Well it's going to be much easier to just change the compression, but
it's not the end of the world if you want to put it off a year or so
(IMO).
