services: avahi: Deprecate the 'avahi-service' procedure.
* gnu/services/avahi.scm (<avahi-configuration>): Export getters. Add default values. (avahi-service-type)[default-value]: New field. (avahi-service): Mark as deprecated. * gnu/services/desktop.scm (%desktop-services): Use the 'service' form instead of calling 'avahi-service'. * gnu/tests/base.scm (%avahi-os): Likewise. * doc/guix.texi (Base Services): Adjust example accordingly. (Networking Services): Update accordingly.
