guix-package: Add `--roll-back'.
Based on a patch by Nikita Karetnikov <nikita@karetnikov.org>. * guix-package.in (profile-regexp): New procedure. (latest-profile-number): Remove `%profile-rx', and use `profile-regexp' instead. (profile-number, roll-back): New procedure. (show-help): Add `--roll-back'. (%options): Likewise. (guix-package)[process-actions]: First check whether `roll-back?' is among OPTS, and call `roll-back' if it is, followed by a recursive call to `process-actions'. Emit the "nothing to be done" message only when INSTALL or REMOVE is non-empty. * tests/guix-package.sh (readlink_base): New function. Add tests for `--roll-back'. * doc/guix.texi (Invoking guix-package): Document `--roll-back'.
