Seems that GVirConfigDomainGraphics* were built with a strong focus on
writing/setting configs, but not reading those.
For instance, considering virt-viewer's case, where the app is just
consuming an already built xml, for getting the port attribute of a
GVirDomainConfigGraphis{Spice,Vnc} you have to know, beforehand, the
type of the connection and then call
gvir_config_domain_graphics_{sdl,spice}_get_port(). It means creating an
abstraction on virt-viewer side, that will ended up in some code like:
if (GVIR_CONFIG_IS_DOMAIN_GRAPHICS_SPICE(graphics))
_get_whatever_you_want_using_specific_spice_api()
else
_get_whatever_you want_using_specific_vnc_api()
In order to avoid this, let's introduce GVirConfigDomainGraphicsRemote
class that, at least for now, is intended to be a helper for the case
explained above. It introduces a new hierarchy in the project, where,
instead of having GVirConfigDomainGraphics{Spice,Vnc,Rdp} inheriting
from GVirCOnfigDomainGraphics, these classes will inherit from
GVirConfigDomainGraphicsRemote (see the next patches) which inherits
from from GVirConfigGraphics (it will cause an ABI breakage, though).
