Use a GstObject subtype for the deinterlacing methods and export
the different settings for each deinterlacing method via GObject
properties.
Implement GstChildProxy interface to allow access to the used
deinterlacing method and to allow adjusting the different settings.
Move global variables of the tomsmocomp deinterlacing method into
function local variables to make it possible to use this deinterlacing
method from different instances.
