9d252137e5 In h264 decoder, fix decoding when nal end sequence is present

00d1e96bf4 H.264 decode: support cropping up to 28 pixels in interlaced mode.
Contrary to progressive, just being able to crop up to 14/15 pixels
is not enough to encode all supported resolutions, and the new
behaviour is also consistent with e.g. MPEG-2 etc.

4dece8c7f8 Try to fix crashes introduced by r25218
r25218 made assumptions about the existence of past reference frames that
weren't necessarily true.

1d16a1cf99 Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm from
h264dsp_mmx.c to h264_idct.asm (as yasm code). Because the loops are now
coded in asm instead of C, this is (depending on the function) up to 50%
faster for cases where gcc didn't do a great job at looping.

Since h264_idct_add8() is now faster than the manual loop setup in h264.c,
in-asm idct calling can now be enabled for chroma as well (see r16207). For
MMX, this is 5% faster. For SSE2 (which isn't done for chroma if h264.c does
the looping), this makes it up to 50% faster. Speed gain overall is ~0.5-1.0%.

4693b031a3 Move H264 dsputil functions into their own struct
This moves the H264-specific functions from DSPContext to the new
H264DSPContext.  The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.

The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

2ce1c2e063 Always reset slice_table.
Previously, the area of a lost slice would be left at the slice number of the previous
frame which could occasionally match the number of the next slice and thus a non existing
slice could have been used for prediction leading to additional decoding errors in otherwise
undamaged slices.
