c2c9801bc9 lavfi: deprecate avfilter_graph_add_filter(). 
Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

bc1a985ba0 lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). 
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

d2fcb356ca pixdesc: add functions for accessing pixel format descriptors. 
Make av_pix_fmt_descriptors table static on next major bump.

Making the table public is dangerous, since the caller has no way to
know how large it actually is. It also prevents adding new fields to
AVPixFmtDescriptor without a major bump.

9a92aea27b avutil: Add functions for allocating opaque contexts for algorithms 
The current API where the plain size is exposed is not of much
use - in most cases it is allocated dynamically anyway.

If allocated e.g. on the stack via an uint8_t array, there's no
guarantee that the struct's members are aligned properly (unless
the array is overallocated and the opaque pointer within it
manually aligned to some unspecified alignment).

239fdf1b4a x86: build: replace mmx2 by mmxext 
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

681ed00099 avf: introduce nobuffer option

analyzeduration is small.
