Add simpler names and a shorthand for native atomics (as opposed to
pthreads fallback).

Add AVBuffer-based reference counting API to it.

These could be used for reference counting, or for keeping track of
decoding progress in references in multithreaded decoders.

Support is provided by gcc/msvc/suncc intrinsics, with a fallback using
pthread mutexes.

This supports HMAC-MD5 and HMAC-SHA1 for now, other hashes are
simple to add.

This reverts commit d15c21e5fa.

After the major bump this is no longer necessary.

Earlier versions of for instance of libavcodec expect this symbol to be
present in libavutil. This commit can be reverted after the next major
bump.

New shared builds of avcodec will link to the internal copy of the
table within that library, so those builds won't rely on this table
being present in avutil any longer either.

This removes inline av_log2 and av_log2_16bit from the public API,
instead exporting them as regular functions.  In-tree code still
gets the inline and otherwise optimised variants.

Add a configure function to pull in a compat object and set up
redirects in one operation.  This avoids duplicating conditions
across configure and makefiles.

The table is so small that the space gain is not worth the
performance overhead of cross-library access.

Move vector_fmul() from DSPContext to AVFloatDSPContext.

The functions operate on the sample level rather than the byte level and work
with all audio sample formats.

This allows simplifying the Makefiles; it is no longer necessary to register
arch subdirectory Makefiles, just putting them in place is enough.

The were broken since August of 2010 without anyone noticing until
three weeks ago. Nobody cares about it anymore and hopefully Marvell
will support NEON like in the PXA978 from now on.

The functions are already av_ prefixed and intfloat header is already provided.
Install libavutil/intfloat.h

Calling Make from subdirectories is not supported and config.mak has
multiple inclusion guards anyway, so the top-level include is enough.

Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

eval.c has moved to libavutil, move the TESTPROGS entry too.

The softfloat functionality is unused, not installed and incomplete.
On platforms without floating point units, the compiler provides a softfloat
implementation so there is no point in carrying this code around locally.

The functions are already av_ prefixed and sha1 header is already provided.
Install libavutil/{aes,sha}.h

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
