libjpeg based jpeg decoder

So this new revision have a couple of changes:

- fix a brown paper bag, i was reading the compressed data 1 (!!) byte at time,
because the silly of me not only was using sizeof() on a malloc'ed area but i
was even dereferencing it. Should now be a lot faster.

- improve the jpeg fscked soi workaround, now it doesn't try to patch the wrong
soi, if there is a sane soi after that it justs skips data. Don't think the old
was correct because libjpeg refused to decode the picture.

Feel free to use this bug to track regressions with dsjpeg.
