5a9dd3de63 Make avfilter_start_frame() invoke avfilter_get_video_buffer() on the 
link rather than avfilter_default_get_video_buffer().

This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").

In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.

e34433612f Rename av_fill_image_max_pixstep() to av_fill_image_max_pixsteps(). 
The plural form is preferred as it is more consistent with the other functions:
av_fill_image_linesizes()
av_fill_image_pointers()

and looks semantically more correct as it fills an array of elements.
