services: slim: Allow SLiM to be started on multiple ttys.
This change makes it possible to add multiple SLiM services to an operating system configuration by setting the new 'display' and 'vt' fields in their configurations to different values. Each SLiM service will get its own authfile, logfile, lockfile, and shepherd service, which will start SLiM on a different tty. * gnu/services/xorg.scm: Export slim-configuration-display and slim-configuration-vt. (<slim-configuration>)[display, vt]: New fields. (slim-shepherd-service): Refactor let. [slim.cfg]: Use new fields for setting display_name, xserver_arguments, authfile, lockfile, and logfile. [shepherd-service][provision]: Name the shepherd service according to the value of 'vt'. [shepherd-service][start]: Delete the right lockfile. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
