Stefano Sabatini c4415f6ec9 lavfi: unify asink_buffer and vsink_buffer API 
The new API is more generic (no distinction between audio/video for
pulling frames), and avoids code duplication.

A backward compatibility layer is kept for avoiding tools ABI breaks
(only for the video binary interface, audio interface was never used
in the tools).

av_lockmgr_register() can be used to register a callback function
that lavc (and in the future, libraries that depend on lavc) can use

When the lock manager is registered, FFmpeg is guaranteed to behave
correctly in a multi-threaded application.
2009-04-30 - r18719 - lavc 52.28.0 - av_free_packet()
av_free_packet() is no longer an inline function. It is now exported.

Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
PIX_FMT_BGR32_1 are now macros.
avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
Re-sort the enum PixelFormat list accordingly.
This change breaks API/ABI backward compatibility.
2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
and av_fifo_realloc2.
In addition, the order of the function arguments of av_fifo_generic_read
was changed to match av_fifo_generic_write.
The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
applications, they may not use sizeof() or directly access members.
2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
Introduce a new metadata API (see av_metadata_get() and friends).
