2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu.
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

ad0c9f2d5d lavc: move AVFrame.hwaccel_picture_private to Picture.
This field is private and should not be present in a public struct. It
is only used in DXVA with mpegvideo-based decoders currently.

add3a6902e lavu: bump major to 52
In addition to the recent tables mess, the AVOption defaults behavior
changed, so an old lavc used with a new lavu will get completely messed
up defaults.

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.
