was generated using faani as idct.

As Nvidia has put the most recent Video Codec SDK behind a double
registration wall, of which one needs manual approval of a lenghty
application, bundling this header saves everyone trying to use NVENC
from that headache.
The header is still MIT licensed and thus fine to bundle with ffmpeg.
Not bundling this header would get ffmpeg stuck at SDK v6, which is
still freely available, holding back future development of the NVENC
encoder.
Making sure bestpos is initialized to zero to prevent gcc from kvetching.
It's harmless (although it's not obvious that it's harmless)
from code inspection:
tests/audiomatch.c: In function ‘main’:
tests/audiomatch.c:40: warning: ‘bestpos’ may be used uninitialized in this function
Thanks to Moritz Barsnick for first bringing this to the attention.

This fixes valgrind warnings about conditional jumps based on
uninitialized data (even though the uninitialized data only ever
was compared with a direct copy of the same uninitialized data).

If this still doesnt give the same results on all platforms then this should be
disabled

When targeting COFF (windows), clang doesn't support this
directive (while binutils supports it for all targets).

These bits are set by exceptions in NEON instructions.
Also print the differing bits when FPSCR is clobbered,
and use bic instead of lsl, for clearing the topmost bits.

Each const block needs to be terminated by one endconst
invocation so either call endconst after each, or just
declare plain labels to the later strings.
This fixes errors such as this, on some binutils versions:
checkasm.S:38: Error: Macro `endconst' was already defined

The stack used by checkasm_checked_call_vfp was a multiple of 4 when the
checked function is called. AAPCS requires a double word (8 byte)
aligned stack public interfaces. Since both calls are public interfaces
the stack is misaligned when the checked is called.
Might fix the SIGBUS error in the armv7-linux-clang-3.7 fate config.
Fix the demuxer dependencies in some of the tests and remove the vp8 decoder
dependency for the stream copy tests
