commit 0c6e51011bb0f6336a5dfaafb2ba02428ed220a9
Author: Christophe Fergeau <cfergeau at redhat.com>

Move RedCharDeviceCallbacks into RedCharDeviceClass
This structure holding virtual function pointers was kept until now as a
RedCharDevice member in order to make the GObject conversion easier.
Now that all RedCharDevice children are converted to GObject, it can be
moved into RedCharDeviceClass.
