guix-package: Always use the next number for new generations.
Suggested by Andreas Enge <andreas@enge.fr> at
<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00325.html>.
* guix-package.in (latest-profile-number): Remove.
(switch-symlinks): New procedure.
(roll-back)[switch-link]: Use it.
(guix-package)[process-actions]: Always choose NUMBER + 1 for the new
profile. Use `switch-symlinks' instead of `symlink'. Remove code to
delete PROFILE when it exists since `switch-symlinks' has the same
effect.
* tests/guix-package.sh: Adjust existing `--roll-back' tests.
* doc/guix.texi (Invoking guix-package): Document this `--roll-back'
behavior.
