docs/random/ds/0.9-suggested-changes: random notes

Original commit message from CVS:
* docs/random/ds/0.9-suggested-changes: random notes
* gst/elements/gstfakesrc.c: (gst_fakesrc_get_formats),
(gst_fakesrc_get_query_types), (gst_fakesrc_get_event_mask):
Replace GST_PAD_EVENT_MASK_FUNCTION() (et al.) with its
expansion.
* gst/elements/gstfilesink.c: (gst_filesink_get_formats),
(gst_filesink_get_query_types): same
* gst/elements/gstfilesrc.c: (gst_filesrc_get_event_mask),
(gst_filesrc_get_query_types), (gst_filesrc_get_formats): same
* gst/gstcaps.h: deprecate GST_DEBUG_CAPS(), and fix the macro
to use new GST_PTR_FORMAT.
* gst/gstelement.h: deprecate function factory macros
GST_ELEMENT_QUERY_TYPE_FUNCTION(), GST_ELEMENT_EVENT_MASK_FUNCTION().
These are our last variadic macros that can't be replaced with
inlines.  Celebrate!  Also fix a typo in an #ifdef that was
attempting to deprecate gst_element_clock_wait().
* gst/gstevent.h: same
* gst/gstpad.c: (gst_pad_link_intersect), (gst_pad_link_fixate),
(gst_pad_try_set_caps): replace GST_DEBUG_CAPS() with GST_DEBUG()
* gst/gstpad.h: deprecate function factory macros similar to above.
