camera: Massive code reworking.

Browse source 
- Simplified public API, simplified backend interface.
- Camera device hotplug events.
- Thread code is split up so it backends that provide own threads can use it.
- Added "dummy" backend.

Note that CoreMedia (Apple) and Android backends need to be updated, as does
the testcamera app (testcameraminimal works).
