93629989a9 py: cam.py: Fix multi camera capture without -C
-C flag is supposed to affect only the camera that was previously
defined in the arguments. That's not the case, and, e.g.:

cam.py -c2 -C -c3

causes camera 3 to start capturing, but it stops after the initial
Requests have been completed.

Fix the issue by filtering out camera contexts that do not have -C
defined.

7ef83e0228 py: Merge read_event() and get_ready_requests()
We always call CameraManager.read_event() and
CameraManager.get_ready_requests(), so to simplify the use merge the
read_event() into the get_ready_requests().

This has the side effect that get_ready_requests() will now block if
there is no event ready. If we ever need to call get_ready_requests() in
a polling manner we will need a new function which behaves differently.

However, afaics the only sensible way to manage the event loop is to use
select/poll on the eventfd and then call get_ready_requests() once,
which is the use case what the current merged function supports.

Instead of doing an mmap and munmap every time a Request is complete,

7330474762 py: cam: Drop PIL dependency
We can use Qt directly to accomplish the same as we do with PIL.

A minor downside is that loading MJPEG frame with Qt produces a "Corrupt
JPEG data" warning. The resulting picture looks fine, though. So add a
message handler to ignore that warning.

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.
