gst/gstbin.c: Fix typos, add comments.

Browse source 
Original commit message from CVS:
* gst/gstbin.c: (is_eos), (update_degree), (gst_bin_change_state),
(gst_bin_dispose), (bin_bus_handler):
Fix typos, add comments.
Clear EOS list when going to PAUSED from any direction and do it
in a threadsafe way.
Get base time in a threadsafe way too.
Fix confusing debug in the change_state function.
Various other mall cleanups.

* gst/gstelement.c: (gst_element_post_message):
Fix very verbose bus posting code.

* gst/gstpipeline.c: (gst_pipeline_class_init),
(gst_pipeline_set_property), (gst_pipeline_get_property),
(gst_pipeline_change_state):
Small ARG_ -> PROP_ cleanup
