- Remove neon, mp4v2 and fam dependencies, since they are not needed
anymore [1]
- Disable hal support by default and andd WITH_HAL knob which turns it
on. However bmpx with hal support might be not stable [1]
- Mark BROKEN on 5.x [2]
- Disable docs installation, they're pretty useless at this moment, but
require additional dependencies
