Codec is too simple to gain much from it at lower resolutions,
but should help at very high resolutions, particularly for
v3 and v5 where a not too optimized pseudo-YUV to RGB
is done in the codec.

This reverts e6e7bfc1 and 365e1ec2.
The code may be incorrect both before and after the revert, but we
do not have any samples that were fixed by the original commits.
Fixes ticket #871.
With gcc 4.6 this part of the code is ca. 4x faster, resulting
in an overall speedup of around 5% for fate-fraps-v5 sample.

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.
Note: This fixes the following GCC warning :-
libavcodec/sunrast.c:94: warning: comparison of unsigned expression < 0 is always false.

Codec has only I- and skip-frames, so there is no
need for reget_buffer, change it so it works with
get_buffer.

Causes FFmpeg to pass through the correct pts values,
instead of clobbering all to AV_NOPTS_VALUE (the av_init_packet
default) to then make up new ones based on only fps when muxing.
Included are also the related FATE ref changes, which all
some reasonable on quick investigation.
Also set all H.264 references to us -vsync drop to reduce the
diff for the ref files.
Otherwise almost all H.264 references need to change, mostly due
to now starting with negative pts values.
About 20 additional H.264 conformance tests needed -vsync
drop anyway because they create pts values that are out of
order and thus not possible to mux otherwise.

10l: Forgot to adjust deinterleave for new location of incoming samples in 7946a5a.
This produced incorrect, but surprisingly listenable results.
Thanks to Justin Ruggles for the report.

This allows to work around any non-monotonic time-stamp errors
by just discarding all time stamps.
This will be necessary to allow H.264 conformance tests to pass
after fixing time stamps to be passed through rawenc.

We may or may not be able to play the latter parts
but not demuxing at all seems like the worst possible behaviour.
Fixes playback of e.g.

As a proper solution either multiple video streams should
be exported or side data should be used to update extradata
if necessary.

Since it is set for e.g. webm muxer we should make it possible
to test such streams with framecrc, too.
Though the primary reason is that this allows the H.264 tests
to not run into this check when fixing raw video encode to
pass pts values on.

The tests work fine without it, and it will cause issues when the
rawvideo decoder is changed to properly handle pts values.
The H.264 conformance tests however are still broken, usually losing
the first frames without it.
