Seriously, this is better than a previous commit as we only need
to notify the fact that an element changed state in a streaming
thread, marking the state of the parents dirty, hence the
STATE_DIRTY message instead of abusing a boolean in a STATE_CHANGE
message.

Print out feature and plugin count at the end when printing out
all features.
Also add a changelog entry which I'd written but not committed?
Original commit message from CVS:

Add another error string used in a few existing plugins.
* gst/gstplugin.c:
* gst/gstpluginfeature.c: (gst_plugin_feature_load):
* tools/gst-inspect.c: (print_element_info):
When a feature disappears from a plugin (and the feature exists in
the cached registry file), things went horribly wrong. This isn't a
complete fix, we should actually be removing the 'missing' features
from the features list when we load the actual plugin. That's not
yet implemented.
Original commit message from CVS:
* gst/gstplugin.c: (gst_plugin_load_file): Make some error messages
more end-user friendly.

Original commit message from CVS:
* gst/gstbus.c: (poll_func), (poll_timeout), (gst_bus_poll):
* tools/gst-launch.c: (main):
The timeout handler should have lower priority than the source
so we don't timeout before popping a message with 0 timeout.

GstBusHandler -> GstBusFunc, return value has the same meaning as
any other GSource (FALSE == remove source).
_add_watch() and _add_watch_full() now take a MessageType mask to
only handle specific types of messages.
_poll() returns the GstMessage instead of the message type to avoid
race conditions.
_have_pending() takes a MessageType mask now too.
Added testsuite for multiple bus watches.
Fix testsuites and applications for new bus API.

necessary.

update it for state naming and API changes. Updates files in
place.

* parse/grammar.y:
* gst/base/gsttypefindhelper.c:
* gst/base/gstbasesink.c:
* gst/gstqueue.c: RPAD fixes.
* gst/gstghostpad.h:
* gst/gstghostpad.c: New ghost pad implementation as full proxy
pads. The tricky thing is they provide both source and sink
interfaces, since they proxy the internal pad for the external
pad, and vice versa. Implement with lower-level ProxyPad objects,
with the interior proxy pad as a child of the exterior ghost pad.
Should write a doc on this.
* gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/.
(gst_pad_set_name, gst_pad_set_parent): Macros removed, use
gst_object API.
* gst/gstpad.c: Big changes. No more stub base GstPad, now all
pads are real pads. No ghost pads in this file. Not documenting
the myriad s/RPAD/PAD/ and REALIZE fixes.
(gst_pad_class_init): Add properties for "direction" and
"template". Both are construct-only, so they can't change during
the life of the pad. Fixes properly deriving from GstPad.
(gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For
derived objects, just set properties when creating the objects via
g_object_new.
(gst_pad_get_parent): Implement as a function, return NULL if the
parent is not an element.
(gst_pad_get_real_parent, gst_pad_add_ghost_pad)
(gst_pad_remove_ghost_pad, gst_pad_realize): Removed.
* gst/gstobject.c (gst_object_class_init): Make name a construct
property. Don't set it in the object init.
* gst/gstelement.c (gst_element_add_pad): Don't allow adding pads
with UNKNOWN direction.
(gst_element_add_ghost_pad): Remove non-orthogonal API. Replace
with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)).
(gst_element_remove_pad): Remove ghost-pad special cases.
(gst_element_pads_activate): Remove rpad cruft.
* gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to
catch the pad's-parent-not-an-element case.
* gst/gst.h: Include gstghostpad.h.
* gst/gst.c (init_post): No more real, ghost pads.
* gst/Makefile.am: Add gstghostpad.[ch].
* check/Makefile.am:
* check/gst/gstbin.c:
* check/gst/gstghostpad.c (test_ghost_pads): Check that linking
into a bin creates ghost pads, and that the refcounts are right.
Partly moved from gstbin.c.
