Original commit message from CVS:
* common/m4/gst-feature.m4: Call -config scripts with
--plugin-libs if it is supported.
* gst/avi/gstavimux.c: (gst_avimux_vidsinkconnect): sequences of
JPEG images are image/jpeg.
* gst/debug/Makefile.am:
* gst/debug/negotiation.c: (gst_negotiation_class_init),
(gst_negotiation_getcaps), (gst_negotiation_pad_link),
(gst_negotiation_update_caps), (gst_negotiation_get_property),
(gst_negotiation_plugin_init): Add a property that acts like
filter caps.
* testsuite/gst-lint:  Move license checking to be a standard
test.
