gst/: Since remove is virtual in GstBin we must not assume the elements GList to have anothing usefull.

Original commit message from CVS:
* gst/gstbin.c: (gst_bin_remove), (gst_bin_dispose):
* gst/gstthread.c: (gst_thread_dispose), (gst_thread_catch),
(gst_thread_main_loop):
Since remove is virtual in GstBin we must not assume the
elements GList to have anothing usefull.
Add some more logging to GstThread and be a bit more paranoid
when resetting the scheduler.
Set the state of the bin to NULL before removing the children.
