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).

2ff67c909c lavc: fix mixing CODEC_ID/AV_CODEC_ID in C++ code.
C++ does not allow to mix different enums, so e.g. code comparing
ACodecID with CodecID would fail to compile with gcc.

This very evil hack should fix this problem.

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
Useful in cases where a significant analyzeduration is
still needed, while minimizing buffering before output.

An example is processing low-latency streams where all
media types won't necessarily come in if the
analyzeduration is small.

d3d3a32c9d lavu: add av_usleep() function
This function implements a delay using the first available
of the following functions:

- nanosleep()
- usleep()
- Sleep() (Windows)

The conditional #includes in time.c are simplified by including
unistd.h and windows.h whenever they are available rather than
having these lines triggered by specific functions.
