Subject: ext/jpeg/: move format setting to inner loop

Original commit message from CVS:
* ext/jpeg/gstjpegdec.c: (gst_jpegdec_get_type):
* ext/jpeg/gstjpegenc.c: (gst_jpegenc_get_type),
(gst_jpegenc_getcaps):
move format setting to inner loop
* gst/ffmpegcolorspace/gstffmpegcolorspace.c:
(gst_ffmpegcolorspace_getcaps):
use GST_PAD_CAPS if available so that we use already negotiated
caps
* gst/qtdemux/qtdemux.c: (gst_qtdemux_loop_header),
(qtdemux_parse_moov), (qtdemux_parse):
extra debugging
* sys/qcam/qcam-Linux.c: (qc_lock_wait), (qc_unlock):
* sys/qcam/qcam-os.c: (qc_lock_wait), (qc_unlock):
move hardcoded path to DEFINE
