The patch has downloadPkgs in yum/__init__.py calling repo.get with
url=basepath, which in turn causes the mirrorlists to not be used and
instead directly fetches the url + relativepath.  

So, the end effect is that if xml:base is specified for a package, then
that url is used instead of the baseurl/mirrorlists value of the repo
itself.  This essentially provides the capability to do 'virtual'
repositories as discussed a couple months back on the metadata list.  

Also, since anaconda doesn't use the yum cli path that triggers the
changes in the patch, I don't think that this will conflict with the
xml:base usage in anaconda for specifying CD location.
