[bug#62298] [PATCH 0/8] Extensible define-configuration & mpd/mympd service fixes

[Bruno Victal]

Highlights:

* Make define-configuration extensible.
  define-configuration can now have extra fields where custom-serializer
  was located.

  * New literals: sanitizer, serializer.
    Support user-specified sanitizers.    

* Fixes <https://issues.guix.gnu.org/61570>.
  * Switch to user-account/group for mympd-service-type as well.

* Make mpd-service-type with pulseaudio usable out-of-the-box.

* Fix a mympd-service-type when logging with syslog.
