bug#63082: [PATCH v2 00/16] Improve out-of-the-box experience with mpd-service-type

[Maxim Cournoyer]

This series harmonize mympd with mypd further, such as using syslog as default
for the log output, and sharing more of the logic for their start slot.
Otherwise it's the same as the previous series, with some clean ups and
changes suggested by Bruno in its review (thanks!).

Maxim Cournoyer (16):
  services: mpd: Add an 'update' action to trigger a database update.
  services: mpd: Streamline mpd-user-sanitizer and mympd-user-sanitizer.
  services: mpd: Rename %set-user-group to set-user-group.
  services: mpd: Obsolete the 'group' field.
  services: mpd: List log-level in decreasing verbosity order in doc.
  services: mpd; Refactor start slot directory initialization.
  services: mpd: Log to syslog by default.
  services: mpd: Do not rotate logs when using syslog.
  services: mpd: Let Shepherd effect the user/group change.
  system: accounts: Export <user-account>.
  services: mpd: Warn when the MPD user is not in the "audio" group.
  services: mpd: Auto-detect mpd-output mixer type by default.
  services: mpd: Obsolete 'environment-variables' field.
  services: mpd: Provision a default cache directory and set HOME.
