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.

Add ControlInfo class and change the controls related methods to
resemble the C++ API (e.g. no more string based control methods).
We don't implement ControlList or ControlInfoMap but just expose the
same data via standard Python dict.

Move MappedFrameBuffer to libcamera.utils, instead of extending
FrameBuffer class with a new mmap() method. This keeps us more aligned
to the C++ API.

Add CameraManager.read_event() so that the user does not need to call
os.read().
We use eventfd, and we must always read 8 bytes. Hiding that inside
read_event() makes sense.

Now that we have proper geometry classes in the Python bindings, change

Implement PixelFormat bindings properly with a PixelFormat class. Change

Catch exceptions in the event_handler, as they would get ignored
otherwise. Print the exception and return False so that the main loop
exits.

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.
