d576e23aa4 basevideoencoder: Proxy the width/height/framerate/PAR constraints of downstream caps to upstream 
This allows to specify constraints on the compressed downstream caps
by muxers or capsfilters, which will then be forwarded to upstream
and allows video converters to fulfill the constraints.

Code based on Mark Nauwelaerts audio encoder base class.

4a76d3a978 basevideoencoder: Remove ::get_caps() vfunc 
Subclasses can set the caps more efficiently and this only
caused additional indirections.

9238647314 photography: add missing FLICKER_REDUCTION capability 
GstPhotography API contains functions to get/set flicker reduction
mode, but GstPhotoCaps enumeration doesn't have item for it, so elements
are not able to report whether they support this feature or not.
Also add useful GST_PHOTOGRAPHY_CAPS_ALL for easily selecting all
capabilities at once.

058a3d9d4c basecamerasrc: remove unused get_allowed_input_caps 
The use of this method was removed in:
    commit 539f10f4d9
    basecamerasrc: More cleanup

The code from wrappercamerabinsrc is from v4l2camerasrc but is unused:
get_allowed_input_caps is not called anywhere.

f341386b64 basevideodecoder: Don't reorder serialized src events

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.

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.
