[PATCH libvirt-glib v2 4/8] Add API for appending a new device to the domain

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

The gvir_config_domain_set_devices API replaces the entire
list of devices, but when building up a config incrementally
it is useful to append device one at a time. Thus we need
a gvir_config_domain_add_device method

* libvirt-gconfig/libvirt-gconfig-domain.c,
  libvirt-gconfig/libvirt-gconfig-domain.h,
  libvirt-gconfig/libvirt-gconfig.syms: gvir_config_domain_add_device
