Fixes crashes with bigger h/v fov.

When duplicating frames we need to schedule for activation again, otherwise frames can build up in the inlink fifo.

Fixes use of uninitialized variables.

Also normalize vector after rotation, it might be needed,
otherwise one can get NaNs.

roll/pitch can do exactly same thing.

Right now, the concat filter does not set the frame_rate value on any of
the out links. As a result, the default ffmpeg behaviour kicks in - to
copy the framerate from the first input to the outputs.

If a later input is higher framerate, this results in dropped frames; if
a later input is lower framerate it might cause judder.

This patch checks if all of the video inputs have the same framerate, and
if not it sets the out link to use '1/0' as the frame rate, the value
meaning "unknown/vfr".

A test is added to verify the VFR behaviour. The existing test for CFR
behaviour passes unchanged.

It is not clear what was real intention of previous commit to this filter.
It was not working correctly, hopefully this is fixed now.
It never checked that new x/y/w/h are actually valid, hopeffully this is fixed now.
It uses named variables in expressions that are never set, still not fixed.
It does not set named variables that uses actual frame widht/height, making actual
expressions less usable for our users, still now fixed.

currently, the layer number is at the beginning of the .model file,
so we have to scan twice in python script, the first scan to get the
layer number. Only one scan needed after put the layer number at the
end of .model file.

the info can be saved in dnn operand object without regenerating again and again,
and it is also needed for layer split/merge, and for memory reuse.

to make things step by step, this patch just focuses on c code,
the change within python script will be added later.
