Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

This allows dropping the av_unused argument from them.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

This sets __OUTPUT_FORMAT__ to win64 instead of win32, even though both
(through -m amd64) produce 64-bit binary code.

Functions using INIT_MMX may still access XMM registers through direct
means (xmm0-15). Therefore, they still need to be marked for clobber
so they can be properly saved/restored.

The spec says the following speaker mapping is default:
center front speaker
left, right center front speakers,
left, right outside front speakers,
left surround, right surround rear speakers,
front low frequency effects speaker

This will be useful to test more aggressively for failures to mark XMM
registers as clobbered in Win64 builds, and prevent regressions thereof.

Based on a patch by Ramiro Polla <ramiro.polla@gmail.com>

The functions are already av_ prefixed and intfloat header is already provided.

Assemblers don't understand ! in %if statements.

This allows combining multiple conditionals in a single statement.

Firstly, this test never worked as intended, always reporting
success.  Secondly, bswap is available from 486 onward and can
thus be assumed present.

With these changes, gcc 4.5 and later recognise it as a bswap
and use the proper instructions on ARM and x86.  On x86, the
16-bit bswap is recognised from gcc 4.1.

The existing functions defined in intfloat_readwrite.[ch] are
both slow and incorrect (infinities are not handled).

This introduces a new header with fast, inline conversion
functions using direct union punning assuming an IEEE-754
system, an assumption already made throughout the code.

The one use of Intel/Motorola extended 80-bit format is
replaced by simpler code sufficient under the present
constraints (positive normal values).

The old functions are marked deprecated and retained for
compatibility.

Solaris Studio (suncc) has difficulty with filling in
members of a union. Instead, let's retrieve and store the
cpuid() results separately. This is still a compiler bug,
however this fix does not cause a regression on other platforms.
