Subject: 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.
