Vittorio Giovara bddd8cbf68 Add transformation matrix API.
Add AV_PKT_DATA_DISPLAYMATRIX and AV_FRAME_DATA_DISPLAYMATRIX as stream and
frame side data (respectively) to describe a display transformation matrix
for linear transformation operations on the decoded video.

Add functions to easily extract a rotation angle from a matrix and
conversely to setup a matrix for a given rotation angle.

Ronald S. Bultje 65f1d45dcc lavu: add support for atomic operations.
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.

Anton Khirnov c6b25d1d5e Revert "avutil: Add a copy of ff_sqrt_tab back into avutil to restore ABI compatibility"
This reverts commit d15c21e5fa.

After the major bump this is no longer necessary.

Martin Storsjö d15c21e5fa avutil: Add a copy of ff_sqrt_tab back into avutil to restore ABI compatibility
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.

Mans Rullgard 8c0a3d5fe0 avutil: remove inline av_log2 from public API
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.
