This patch series introduces a new set of AEGC controls that allow:
- flicker avoidance when switching from auto to manual
- shutter priority / gain priority

To achieve this, we remove the existing AeEnable control and add two
separate controls that control enabling/disabling auto-exposure and
auto-gain. The definition of AeState is also made more concrete. The
first two patches add the new controls, as well as documentation and
design rationale.

The rest of the patches naturally update the existing users of AeEnable,
before finally removing the control altogether.

Thanks,

Paul
