camerabin2: Fix order of element state change
...
To change the state of elements in a pipeline, we should mirror the
behaviour of GstBin which starts at the sink element and works its way
upstream.

basevideodecoder: invoke subclass start method at state change and use set_format
...
While this changes API slightly (e.g. actually uses set_format now), which is OK
for unstable API, it has following merits:
* symmetric w.r.t. stop at state change
* in line with other base class practice
* otherwise no subclass method at state change (global activation time)
Moreover, subclassese are either unaffected or trivially adjusted accordingly.

basevideoencoder: invoke subclass start method at state change
...
While this changes order w.r.t. set_format, which is OK for unstable API,
it has following merits:
* symmetric w.r.t. stop at state change
* in line with other base class practice
* little benefit in invoking 2 subclass virtual methods (set_format and start)
in immediate succession; all actions in the second could be done in the first
whereas subclass has no chance to do anything 'global' at activation time
Moreover, current -bad subclass relevant methods either trivially commute
or are either trivially adjusted accordingly.
