Original commit message from CVS:
* ext/dc1394/gstdc1394.c: (gst_dc1394_src_fixate),
(gst_dc1394_create), (gst_dc1394_caps_set_format_vmode_caps),
(gst_dc1394_set_caps_framesize_range),
(gst_dc1394_caps_set_framerate_list), (gst_dc1394_get_cam_caps),
(gst_dc1394_framerate_frac_to_const),
(gst_dc1394_open_cam_with_best_caps):
Make a bunch of functions static, and move variable declarations
to the start of blocks to avoid problems on older gcc.
Make sure to unset value types.
