is deprecated and will be dropped at the next major bump.

15ba015f71 The vflip filter does not need to keep ownership of a picture reference. 
Avoid creating and releasing useless extra picture references in the
start_frame and end_frame callbacks.

91d1c741bf Create a set of null callback functions. 
These are useful for filters which don't modify the image data.

5bb5c1dc86 Add AVFilterPicRef.pos field and make libavfilter propagate stream 
byte position information, as stored in the pkt.pos, through the
filterchain.

Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.

ec7ab610d5 Extend the slice filter to make it issue slice height values randomly 
choosen between 8 and 32 when the supplied parameter is the string
"random".

This is useful for testing the slice support, but it is not supposed
to be used for other purposes and this interface may change in the
future, thus it is not documented.

The randomization algorithm adopted is the standard Numerical Recipes
LCG.

b5eab66e9f Make avfilter_default_start_frame() request a buffer with the same 
size of the output link of the destination filter, rather than of the
size of the input link.
In particular this fixes a crash in the rotate filter.
