Wim Taymans 1bd751372e Cleanups
Remove unused events, drained and marker can be done with
ASYNC_COMPLETED messages
Handle result of idle callback to disable the poll item
Identify poll items with a unique id.
Remove set_state vfunc
push_event -> send_command, commands are to do something, events are the
result of something.
Add poll item in v4l2 as soon as we have the fd but disable the item
until streaming starts.
