v4l2-ctrls: must be able to enable/disable controlsctrl-enable

Controls can be dependent on the chosen input/output. So it has to be possible
to enable or disable groups of controls, preventing them from being seen in
the application.

We need to allow duplicate controls as well so that two control handlers
that both have the same control will still work. The first enabled control
will win. And duplicate controls are always sorted based on when they were
added (so the sorted list and the hash are both stable lists/hashes).
