videomixer: Implement sinkpad GetCapsFunction.
...
This allows returning only the formats, width, height, framerate
and pixel-aspect-ratio that downstream can support.

videomixer: Add i387 floating point registers to the clobbered registers list
...
They are the same as the mm0-mm7 MMX registers and will be overwritten
by the assembly code if gcc doesn't know about the MMX registers.
Note: They're all added to the list of clobbered registers in all cases
and not only when __MMX__ is not defined just to make sure that no other
bugs happen with this code just because some compiler version gets things
wrong.

videomixer: use 'q' constraint instead of 'r'
...
This avoids the "bad register name `%dil'" compilation errors on 32bit where
because of 'r' gcc puts the value in a general purpose register and then tries
to access the lower part as %dil/%sil which is not existing on 32bit. 'q' requests
a-d registers

videomixer: Implement basic QoS
...
This drops frames if they're too late anyway before blending and all
that starts but QoS events are not forwarded upstream. In the future
the QoS events should be transformed somehow and forwarded upstream.
