Problem caused by buffer overflow in strcpy.

Broke sliced-threads + slice-max-size/slice-max-mbs.

Slightly faster encoding with lots of slices.

Saves around 100 million clock cycles on x264 init.

Also kill all Hungarian notation while we're at it.
Trim an instruction off cabac_encode_bypass.

Get rid of redundant warnings upon encoder_reconfig calls.
Also avoid encoder_reconfig turning off psy_rd/trellis.

Should improve quality with FPSs much larger or smaller than 25.

Fixes build with lavf/lavc 53.

Use dec_ref_pic_marking SEIs to repeat B-ref referencing information.
Don't allow B-frames to reference frames outside their minigop.

This option is now required for Blu-ray compatibility.
--open-gop bluray is now gone (using bluray-compat and open-gop implies a Blu-ray compatible open-gop).
This option doesn't automatically enforce every aspect of Blu-ray compatibility (e.g. resolution, framerate, level, etc).

Uses GCC vector intrinsics; may be suboptimal on particularly old GCC versions.

Caused a speed penalty against gcc equivalents.

This is a counter to the proliferation of incredibly stupid psnr/ssim "benchmarks" of x264 in which the benchmarker conveniently "forgot" --tune psnr/ssim, crippling x264 in the test.

Row SATDs were slightly incorrect.

Fix a comment typo.
Align an array properly.
Make x264_scan8 unsigned: saves a bunch of movsxd instructions on x86_64.

Fixes configuration with Intel compiler in some cases.

Instead, if it happens, just re-encode the MB at higher QPs until it fits.

SSE2/SSSE3/SSE4/AVX implementations.
About 3x faster.

These aren't merged versions, they just call the existing asm code.
A merged implementation would of course be faster.

Also fix broken thread detection on cygwin.

Reduces Intel Compiler's bias against non-Intel CPUs.

Big thanks to Agner for the original information on how to do this.

Big thanks to David Rudie, the original author of this patch.

Doesn't affect compiled output outside of LLVM.

SSSE3 code got used in MMX/SSE2 and vice versa (in hpel).

Caused problems for some players.
