This can be useful for decoding AAC object types that are not supported
by the native AAC decoder, e.g. AAC-LD and AAC-ELD.

Add one copy of the function into each of the libraries, similarly
to what we do for log2_tab. When using static libs, only one
copy of the file_open.o object file gets included, while when
using shared libraries, each of them get a copy of its own.

This fixes DLL builds with a statically linked C runtime, where
each DLL effectively has got its own instance of the C runtime,
where file descriptors can't be shared across runtimes.

On systems not using msvcrt, the function is not duplicated.

This fixes standalone compilation of the msmpeg4v2, msmpeg4v3
and wmv2 encoders, that previously failed to link due to the
decoder codepaths requiring error_resilience.

This makes the DCA parser and decoder independent.

Encoders requiring it have the dependency expressed in the
configure.

The sh4 optimizations are removed, because the code is
100% identical to the C code, so it is unlikely to
provide any real practical benefit.

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.

Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

Support older libvpx versions.

Snow is a toy codec with no real-world use and horrible code.

Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

Fixes linking with only the FLAC encoder enabled.

All the non deprecated functions are in avpicture.c now.

This isn't too useful as a normal codec, but can be used in
voip style applications. The decoder updates the noise
generator parameters when a packet is given to it for decoding,
but if called with an empty packet, it generates more noise
according to the last parameters.

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.

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

A new hidden config variable is added for the codecs that depend on the
mpegaudio parts.
