dfdc6255f8 camerabin2: Fix tag handling for videos 
In video mode the tags should be pushed after sending the start capture
to the source, this allows the video recording elements to be reset
and leave the flushing state they were at after a previous capture.

This fixes the problem where tags only work for the first video capture

c86d662b23 basecamerabinsrc: Handle errors from preview pipeline 
Implements a message handling function to preview pipeline bus.
If GST_MESSAGE_ERROR is seen, considers preview pipeline unable
to do its job and posts an error message to application.

Sets pipeline element to NULL so that subsequent calls to post_preview
and set_caps functions just returns without pushing anything to the
disposed preview pipeline. Leaves further actions to the application.

802028081c basecamerabinsrc: Protection for previewpipeline when setting new preview caps 
Implements a state indicating flag to preview pipeline,
so that new caps are not set if the pipeline is processing a
preview. The caps are set as pending and applied when the
next preview post is called.

In this case a wait was implemented in the post_preview function,
so that new preview image buffer will wait until the other previews
have been posted to the application and the new caps can be used
safely.

74d4030e3f 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.

f591361d2f 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.

4b5623d687 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.
