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.

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.
