* qatar/master:
Partially merged:flvdec: Allow parsing keyframes metadata without seeking in most cases
Error out if vaapi is not found
avio: undeprecate av_url_read_fseek/fpause under nicer names
libvo-*: Don't use deprecated sample format names and enum names
DUPLICATE flvdec: Fix support for flvtool2 "keyframes based" generated index
DUPLICATE libavcodec: Use "const enum AVSampleFormat[]" in AVCodec initialization
Fix the conversion of AV_SAMPLE_FMT_FLT and _DBL to AV_SAMPLE_FMT_S32.
Convert some undefined 1<<31 shifts into 1U<<31.

According to ISO 9899:1999 S 6.5.7/4:
The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the
result is E1× 2^E2, reduced modulo one more than the maximum value
representable in the result type. If E1 has a signed type and
nonnegative value, and E1× 2^E2 is representable in the result type, then
that is the resulting value; otherwise, the behavior is undefined.
On PPC a leaf function has a 288-byte red zone below the stack pointer,
sparing these functions the chore of setting up a full stack frame.
When a function call is disguised within an inline asm block, the
compiler might not adjust the stack pointer as required before a
function call, resulting in the red zone being clobbered.
Moving the entire function to pure asm avoids this problem and also
results in somewhat better code.

PMCs, and with Apple's CHUD it's fairly easy too. No reason to keep useless
code around
2) make the PPC perf stuff a configure option
3) make put_pixels16_altivec a bit faster by unrolling the loop by 4
