The control-center may call g_option_context_parse repeatedly,
so we need to reset the static variables used to hold the parsing
results, otherwise things like the search string may leak from
a previous parsing run.

The name of the file was also changed to calibratorgui.c/h to avoid
it being inconsistent, this way it is no longer dependent on the
the technology.

Turn Control Center in a DBus-activable service and export a
'launch-panel' GAction which accepts a tuple containing the id of the
desired panel and its parameters as a GVariant array.
The snippet below show how the custom shortcuts section of the keyboard
panel can be invoked by a external programs through DBus:
GVariantBuilder *flags = g_variant_builder_new (G_VARIANT_TYPE_VARDICT);
GVariantBuilder *params = g_variant_builder_new (G_VARIANT_TYPE ("av"));
g_variant_builder_add (params, "v", g_variant_builder_end (flags));
g_variant_builder_add (params, "v", g_variant_new_string ("shortcuts"));
g_variant_builder_add (params, "v", g_variant_new_string ("custom"));
GVariant *v = g_variant_new ("(s@av)", "keyboard", g_variant_builder_end (params));
GApplication *gnomecc = g_application_new (id, G_APPLICATION_IS_LAUNCHER);
if (!g_application_register (gnomecc, NULL, &error))
g_error ("Failed to register launcher for %s: %s", id, error->message);
g_action_group_activate_action (G_ACTION_GROUP (gnomecc), "launch-panel", v);

Add a class method to CcPanel to get a GOptionGroup which will be added
to the main commandline parser. This gives panels the chance to have
commandline "--flags" in addition to the already available parameters.
This changes changes the way parameters are passed to panels: the first
entry in the GVariant array is always the a{sv} dictionary of
commandline flags, followed by the remaining free-form arguments.

By using a GVariant of type "av" we can potentially pass more structured
data to panels, which will become relevant with the ability to invoke
them by GAction-based DBus-activation introduced in the following patch.

This promotes better encapsulation and allows us to move
application logic out of main() and rename the confusingly
named control-center.c to main.c
