0838e7316b Add a filter to act as a buffer between filters which may output multiple 
frames for a single call to request_filter(), and a following filter which
assumes it will only receive one frame per call.

a4af86c878 Track the permissions that have been given out to each picture. 
This should make it easier to know what can be done to a buffer once
it's been passed to your filter without falling back to copying it "just
to be safe".

c5ef7d7b3e Make input/output pads modifiable on a per-instance basis. 
This makes it possible to change filter callbacks (eg. to a SIMD version
on supported processors).  It also allows filters to change their own
input and output pads.
