Fixes issue #37504 (see: https://bugs.gnu.org/37504).
The bug was caused by the fact that destructuring an <ntp-configuration>
record using match would bind the 'servers' field without using the
compatibility accessor.
* gnu/services/networking.scm (ntp-shepherd-service): Replace `match-lambda'
by distinct `lambda' and `match' calls, so that the 'servers' field can be
generated by applying the `ntp-configuration-servers' procedure to the
configuration object.
* gnu/services/networking.scm (ntp-server->string): Use the textual
representation of the values as printed by 'display' rather than 'write', to
avoid inserting double quotes in the generated config.
* tests/networking.scm (%ntp-server-sample): Add a comment and make one of the
options a string, to exercise the fix.
("ntp-server->string"): Move the expected value to the first argument.
("ntp configuration servers deprecated form"): Likewise.
("openntpd generated config string ends with a newline"): Likewise.
* gnu/services/audio.scm (<mpd-output>): New record type.
(<mpd-configuration>)[outputs]: New field.
(mpd-output, mpd-output?, mpd-output->string): New procedures.
(mpd-config->file): Use mpd-output->string.
* doc/guix.texi (Audio Services): Document mpd-output fields.
This is a followup to commit 62c2217570.
* gnu/services/base.scm (agetty-shepherd-service)[start]: Wrap un

Unlike gdm-service-type, sddm-service-type cannot be configured in an
operating-system configuration by simply adding (service
sddm-service-type). This adds the default SDDM configuration just like
GDM does..
