Original commit message from CVS:
2004-01-12  Benjamin Otte  <in7y118@public.uni-hamburg.de>

* gst-libs/gst/tuner/tuner.c: (gst_tuner_class_init),
(gst_tuner_find_norm_by_name), (gst_v4l2_find_channel_by_name),
(gst_tuner_channel_changed), (gst_tuner_norm_changed),
(gst_tuner_frequency_changed), (gst_tuner_signal_changed):
* gst-libs/gst/tuner/tuner.h:
GObjects aren't const.
Add find_by_name functions.
Add checks to _changed functions.
* sys/v4l/gstv4ltuner.c: (gst_v4l_tuner_get_channel),
(gst_v4l_tuner_get_norm):
Fixes for above.
