6b03900382 x86 dsputil: provide SSE2/SSSE3 versions of bswap_buf
While pshufb allows emulating bswap on XMM registers for SSSE3, more
shuffling is needed for SSE2. Alignment is critical, so specific codepaths
are provided for this case.

For the huffyuv sequence "angels_480-huffyuvcompress.avi":
C (using bswap instruction): ~ 55k cycles
SSE2:                        ~ 40k cycles
SSSE3 using unaligned loads: ~ 35k cycles
SSSE3 using aligned loads:   ~ 30k cycles

331e7c4cb3 imdct36: mark SSE functions as using all 16 XMM registers.
On x86-64, it indeed uses all 16 registers (and on x86-32, this gets
clipped to 8). Not marking it properly causes callers of this function
to fail randomly because of XMM register clobbering.

This produced incorrect, but surprisingly listenable results.

9a7dc618c5 libavcodec: Don't crash in avcodec_encode_audio if time_base isn't set
Earlier, calling avcodec_encode_audio worked fine even if time_base
wasn't set. Now it crashes due to trying to scale the output pts to
the codec context time base. This affects e.g. VLC.

If no time_base is set for audio codecs, set it to the sample
rate.
