Use https for URL / Source as well as smaller tar.xz files

Using https URL's for source files provides a little more security for
those downloading the code.  Packagers, of course, should be verifying
the GPG signature files before pushing new releases to Fedora's source
cache¹.

While we're changing the source URL's, we might as well use the smaller
tar.xz files which upstream provides.  (This requires minor adjustments
to the unpacking of prebuilt html and man tarballs; tar on el5 does not
know how to automatically filter via xz.)

¹ Replace .xz with .sign for the signatures, which are made against the
uncompressed tarballs.
