maint: distribute .xz tarballs, not .bz2 ones

Many GNU packages are moving towards xz-compressed tarballs, so
let's follow suit, by dropping the creation and distribution of
a bzip2-compressed tarball and switching to xz instead.
For compatibility and safeness, we will continue to create and
distribute a gzip-compressed tarball as well.

* configure.ac (AM_INIT_AUTOMAKE): Drop `dist-bzip2', add
`dist-xz'.
* NEWS: Update.

Suggested by Jim Meyering.
