"SAR" (Sample Aspect Ratio) is globally preferred over "PAR" (Pixel
Aspect Ratio), although the two terms share the same semantics.

For example the corresponding AVStream field is called
sample_aspect_ratio, and libavfilter has a filter named setsar.

Therefore prefer the term "SAR" over "PAR" in the
libavformat/utils.c:dump_stream_format() and avcodec_string() output
for avoiding confusion.

This is required for extending lavfi tests to audio filtering.

Previously the string for AV_CH_LAYOUT_5POINT{0,1}_BACK was the same
of the string for AV_CH_LAYOUT_5POINT{0,1}.

This is required for discerning the two channel layouts, given a
channel layout string.

The functions and tables initialised in this function rely on an
initialised DSPContext.  Make sure they always have one.

Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical
for most codecs, move Bink IDCT into separate context. Get rid of an additional
permutation table while at it since SIMD support for Bink IDCT is unlikely to
be implemented in foreseeable future.
Quantisation tables also have to change type to signed for proper
dequantisation of DCT coefficients.

Avoid the use of the brittle/inconsistent information in
PixFmtInfo.depth, and implement a possibly more robust logic which
exposes the information in pixdesc.

Also allow the removal of PixFmtInfo.depth, since this is the only use
of it.

Directly call sws_isSupportedInput/Output.

The upcoming gcc 4.7 has more advanced constant propagation
resulting some inline asm operands becoming constants and thus
emitted as literals, sometimes in contexts where this results
in invalid instructions.

This patch changes the constraints of the relevant operands
to "rm" thus forcing a valid type.  While obviously suboptimal,
this is what older gcc versions already did, and there is no
change to the code generated with these.

We dereferenced the pointer two lines above, no point in
checking for NULL afterwards.
In addition it cannot be NULL the way it was initialized
just one line further above.

The field is only used for checking if a format is YUV planar
and if the format is paletted.

This patch replaces the current is_planar_yuv() code with a function
which uses the pixdesc information. The new implementation is less
efficient, but this should not be an issue as the functions which use
it (av_picture_crop/pad()) are deprecated and currently never used in
the codebase.
