Don't rescan from the start for every buffer pushed in

I created a basic jpegparse element (see attachment (id=135877) to Bug 583098
).  This patch applies on top of that.  It's not entirely trivial to port this
patch to jpegdec itself, as I'm using an adapter rather than a custom buffer.

Note that there still is a copy for every buffer pushed in.  To avoid this,
something should be added to GstAdapter so you can peek at an offset.
