Factorize code, extend the functionality of the filter, and make it
return empty buffers. This is useful for filters which ignore the input
frames content.

This is also changing the syntax of the nullsrc source, and dropping the
framerate expression evaluation, which does not look particularly useful.

This is no longer a valid configure option.

In particular, fix sliding color bar with padded data, for example with
testsrc,pad=iw+200:ih.

This filter does not support slice-drawing, the whole blurred image needs
to be written in end_frame().

Code is about 2x as fast as previous

This fixes assembling using "nasm".

for example:
Attempting to set ac3 dsur_mode to "on" results in:
[AC-3 Encoder @ 0x7f508f0a3280] Value 2.000000 for parameter 'dsur_mode' out of range
[AC-3 Encoder @ 0x7f508f0a3280] Error setting option dsur_mode to value on.
