Loop is ignored by default.

While this is not always optimal, in practice most of the common cases are.

233 to 105 cycles on Arrandale and Win64.
Replacing the multiplication by s_m[m] by a pand and a pxor with
appropriate vectors is slower. Unrolling is a 15 cycles win.
A SSE version was 4 cycles slower.

CC are not marked. Also allow potential mixed types later.

To define accurately the delay between two frames, it is necessary to
have both available. Before this commit, the first frame had a delay of
0; while in practice the problem is not visible in most situation, it is
problematic with low frame rate and large scene change.

This commit notably fixes output generated with commands such as:

  ffmpeg -i big_buck_bunny_1080p_h264.mov
     -vf "select='gt(scene,0.4)',scale=320:-1,setpts=N/TB"
     -frames:v 5 -y out.gif

Also, to avoid odd loop delays, the N-1 delay is duplicated for the last
frame.

Based on a patch by Vittorio Giovara <vittorio.giovara@gmail.com>

Fixes Bug 378.

Needed e.g. for h264 cropping to work properly.

Fixes seeking without a Xing/Info header.

pkt->duration can not be used since the values are only based on frame
rate.

The encoder now doesn't produce any extra graphic control extension
block anymore. Only the image is encoded, and the muxer writing
its own GCE containing notably the timing information now includes the
optional palette transmitted through packet side data.

This commit avoid setting clashes between the two GCE, and reduce the
size of the generated file with pal8 output.

This allows encoders to communicate side data to the muxers.

Regression since c10d498b.
Unfortunately ff_thread_get_format can only be called from
a separate decode thread, running it during init will fail.
Fixes for that are welcome, for now just revert back to
calling avctx->get_format directly, which is correct
but having to decide on a case-by-case basis which approach
to use is a bit messy.
