gst/elements/gstfilesrc.*: send NEW_MEDIA events correctly

Browse source 
Original commit message from CVS:
* gst/elements/gstfilesrc.c: (gst_filesrc_get),
(gst_filesrc_change_state), (gst_filesrc_srcpad_event):
* gst/elements/gstfilesrc.h:
send NEW_MEDIA events correctly
* gst/elements/gsttypefindelement.c: (start_typefinding),
(gst_type_find_element_handle_event):
restart typefinding when we get a NEW_MEDIA event
* gst/gstbin.c: (gst_bin_remove_func), (gst_bin_change_state),
(gst_bin_dispose):
don't die when someone removes elements in callbacks
* gst/gstelement.c: (gst_element_change_state):
improve debugging
* gst/gstpad.c: (gst_pad_pull), (gst_pad_call_chain_function):
we need a NEW_MEDIA event to engage a link
* gst/gsttrace.c: (gst_trace_new), (gst_alloc_trace_set_flags_all):
don't g_print debugging stuff
* testsuite/caps/simplify.c: (check_caps):
