camerabin2: imagecapturebin: Fix tags merging mode
...

and fix the use case where the last sent tags should be serialized
to the captured images.

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

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.

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.

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.
