Tomi Valkeinen b7c78879cc py: cam_kms: Fix multistream display 
Instead of doing an atomic commit for each stream, do a single commit
for the two planes. This fixes the issue that only the first plane was
actually shown.

Tomi Valkeinen 1384cedf50 py: cam.py: Exit on exception 
Catch exceptions in the event_handler, as they would get ignored
otherwise. Print the exception and return False so that the main loop
exits.

Tomi Valkeinen 74ba01121a py: Add cam.py 
Add cam.py, which mimics the 'cam' tool. Four rendering backends are
added:

* null - Do nothing
* kms - Use KMS with dmabufs
* qt - SW render on a Qt window
* qtgl - OpenGL render on a Qt window

All the renderers handle only a few pixel formats, and especially the GL
renderer is just a prototype.
