Tomi ValkeinenandLaurent Pinchart bf3dbaece9 py: Switch to non-blocking eventfd 
Blocking wait can be easily implemented on top in Python, so rather than
supporting only blocking reads, or supporting both non-blocking and
blocking reads, let's support only non-blocking reads.

Tomi ValkeinenandLaurent Pinchart f814b1b6a9 py: Create PyCameraManager 
Wrap the CameraManager with a PyCameraManager class and move the related
code inside the new class.

This helps understanding the life times of the used-to-be global
variables, gets rid of static handleRequestCompleted function, and
allows us to simplify the binding code as the more complex pieces are
inside the class.

There should be no user visible functional changes.
