ba87f0801d Remove explicit filename from Doxygen @file commands. 
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

3748b2b8e8 Fix leak in avfilter_graph_add_filter(). 
In case of reallocation failure the pointer to the original filter
array was lost. The correct behavior seems to just keep the old array
and count.

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
