Fixes <https://issues.guix.gnu.org/56799>.
This partially reverts 8cb1a49a39.
Rationale: *unspecified* cannot be serialized thus used as a G-Expression
input, which is problematic/inconvenient when using deeply nested records. As
an example, jami-service-type was broken when using partially defined
<jami-account> records.
* gnu/services/configuration.scm (define-maybe-helper): Check against the
'unset symbol.
(normalize-field-type+def): Adjust value to 'unset.
(define-configuration-helper): Use 'unset as the default value thunk.
* gnu/services/file-sharing.scm (serialize-maybe-string): Check against the
'unset symbol.
(serialize-maybe-file-object): Likewise.
* gnu/services/messaging.scm (define-all-configurations): Use 'unset as
value.
(raw-content?): Check against 'unset symbol.
(prosody-configuration)[http-max-content-size]: Default to 'unset.
[http-external-url]: Likewise.
[mod-muc]: Likewise.
[raw-content]: Likewise.
* gnu/services/networking.scm (opendht-configuration): Adjust documentation.
* gnu/services/telephony.scm (jami-shepherd-services): Replace *undefined*
with the 'unset symbol.
* tests/services/configuration.scm ("maybe type, no default"): Check against
the 'unset symbol.
* doc/guix.texi: Regenerate the opendht-configuration,
openvpn-client-configuration and openvpn-server-configuration documentation.
Use *unspecified* as a marker for field values that have not been set.
Rationale: 'disabled may easily clash with user values for boolean fields, is
confusing (i.e. its meaning is *not* boolean false, but unspecified) and it
also passes silently through the symbol? predicate of a field of type symbol.
* gnu/services/configuration.scm (configuration-missing-default-value):
Renamed from configuration-no-default-value.
(define-maybe-helper): Use *unspecified* instead of 'disabled, and make
the default value optional.
* gnu/home/services/desktop.scm (home-redshift-configuration):
Change (maybe-xyz 'disabled) to maybe-xyz.
* gnu/services/authentication.scm (nslcd-configuration): Likewise.
* gnu/services/cgit.scm (repository-cgit-configuration): Likewise.
* gnu/services/file-sharing.scm (serialize-maybe-string)
(serialize-maybe-file-object): Use 'unspecified?' instead of (eq? val
'disabled).

This partially fixes <https://issues.guix.gnu.org/54786>, allowing the 'jami'
and 'jami-provisioning' system tests to pass again.
In version 0.9.0, Shepherd constructors are now run concurrently, via
cooperative scheduling (Guile Fibers). The Jami service previously relied on
blocking sleeps while polling for D-Bus services to become ready after forking
a process; this wouldn't work anymore since while blocking the service process
wouldn't be given the chance to finish starting. The new reliance on Fibers
in Shepherd's fork+exec-command in the helper 'send-dbus' procedure also meant
that it wouldn't work outside of Shepherd anymore. Finally, the
'start-service' Shepherd procedure used in the test suite would cause the Jami
daemon to be spawned multiple times (a bug introduced in Shepherd 0.9.0).
To fix/simplify these problems, this change does the following:
1. Use the Guile AC/D-Bus library for D-Bus communication, which simplify
things, such as avoiding the need to fork 'dbus-send' processes.
2. The non-blocking 'sleep' version of Fiber is used for the 'with-retries'
waiting syntax.
3. A 'dbus' package variant is used to adjust the session bus configuration,
tailoring it for the use case at hand.
4. Avoid start-service in the tests, preferring 'jami-service-available?' for
now.

(jami-shepherd-services): Add the closure of guile-ac-d-bus and guile-fibers
as extensions. Adjust imported modules. Remove no longer used parameters.
<jami-dbus-session>: Use a PID file, avoiding the need for the manual
synchronization.
<jami>: Set DBUS_SESSION_BUS_ADDRESS environment variable. Poll using
'jami-service-available?' instead of 'dbus-service-available?'.
* gnu/tests/telephony.scm (run-jami-test): Add needed Guile extensions. Set
DBUS_SESSION_BUS_ADDRESS environment variable. Adjust all tests to use
'jami-service-available?' to determine if the service is started rather than
the now problematic Shepherd's 'start-service'.
* gnu/services/telephony.scm (murmur-activation):
(murmur-shepherd-service): Change file name of mumble server, which is
now called mumble-server instead of murmurd since version 1.4.x.
