The new request_new_pad_full vmethod provides an additional caps field,
which allows elements to take better decision process.
Also, add a gst_element_request_pad() function to allow developers to be
able to specify which pad template they want a pad of.
Convert gstutils to use that new method instead of the old one when more
efficient.
This is useful for being able to request pads in a more flexible way,
especially when the element can provide pads whose caps depend on
runtime configuration and therefore can't provide pre-registered
pad templates.

Add a GstStructure to GstElementClass and GstElementFactory. Add setters/getter.
Handle it in the registry code. Print items in gst-inspect.
Fixes#396774.

Add a start_time field and some methods. The start_time will contain the
running_time of when the element last went to paused. This time can be user to
report the position in PAUSED but also to do more correct clipping and
stepping later.
Add a gst_element_lost_state_full() with an extra argument to control
distribution of a new base_time. We will need this for flushing step
operations.

Original commit message from CVS:
* gst/gstelement.c:
* gst/gstelement.h:
Deprecated gst_element_get_pad() as it can't be used sanely. It's not
clear of the reference to the resulting pad must be released later
or not, resulting in possible leaks. Fixes bug #533865.
Original commit message from CVS:
* gst/gstelement.c: (gst_element_class_set_details_simple):

recalculation thread.
Don't change state of element with a pending ASYNC_START message.

Perform latency query and configuration when going to PLAYING.

Add GST_USING_PRINTF_EXTENSION to gstconfig.h so that we know
whether we can use G_GNUC_PRINTF in other header files and at
least check the printf format/arguments of debug messages and
GST_ELEMENT_ERROR messages when the printf extension is not
being used.
Replace more tabs with spaces in gstinfo.h and remove two spurious
function declarations in GST_DISABLE_DEBUG part with macros.

* 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.

Added GstSystemClock test.
Implemented clock distribution code in GstBin.
Implemented iterate sinks method for future use.
Rearranged gstelement.h
Fix GstIterator comparison bug.
Moved some code to GstPipeline, mostly clocking related.
Original commit message from CVS:
Remove threadsafe properties. Fix elements because GObject
complains when installing a property before declaring a
set/get_property handler.
Rearrange gstelement.h file, use STATE macros for state locks.
Free mutexes in the finalize method instead of dispose.
Original commit message from CVS:
First THREADED backport attempt, focusing on adding locks and
making sure the API is threadsafe. Needs more work. More docs
follow this week.

I added a mess of prototypes at the top of the file by way of
documentation. Some of the operations on chains and groups were
re-organized.
(create_group): Added a type argument so if the group is enabled,
the setup_group_scheduler knows what to do.
(group_elements): Added a type argument here, too, to be passed on
to create_group.
(group_element_set_enabled): If an unlinked PLAYING element is
added to a bin, we have to create a new group to hold the element,
and this function will be called before the group is added to the
chain. Thus we have a valid case for group->chain==NULL. Instead
of calling chain_group_set_enabled, just set the flag on the group
(the chain's status will be set when the group is added to it).
(gst_opt_scheduler_state_transition, chain_group_set_enabled):
Setup the group scheduler when the group is enabled, not
specifically when an element goes PAUSED->PLAYING. This means
PLAYING elements can be added, linked, and scheduled into a
PLAYING pipeline, as was intended.
(add_to_group): Don't ref the group twice. I don't know when this
double-ref got in here. Removing it has the potential to cause
segfaults if other parts of the scheduler are buggy. If you find
that the scheduler is segfaulting for you, put in an extra ref
here and see if that hacks over the underlying issue. Of course,
then find out what code is unreffing a group it doesn't own...
(create_group): Make the extra refcount floating, and remove it
after adding the element. This means that...
(unref_group): Destroy when the refcount reaches 0, not 1, like
every other refcounted object in the known universe.
(remove_from_group): When a group becomes empty, set it to be not
active, and remove it from its chain. Don't unref it again,
there's no floating reference any more.
(destroy_group): We have to remove the group from the chain in
remove_from_group (rather than here) to break refcounting cycles
(the chain always has a ref on the group). So assert that
group->chain==NULL.
(ref_group_by_count): Removed, it was commented out anyway.
(merge_chains): Use the remove_from_chain and add_to_chain
primitives to do the reparenting, instead of rolling our own
implementation.
(add_to_chain): The first non-disabled group in the chain's group
list will be the entry point for the chain. Because buffers can
accumulate in loop elements' peer bufpens, we preferentially
schedule loop groups before get groups to avoid unnecessary
execution of get-based groups when the bufpens are already full.
(gst_opt_scheduler_schedule_run_queue): Debug fixes.
(get_group_schedule_function): Ditto.
(loop_group_schedule_function): Ditto.
(gst_opt_scheduler_loop_wrapper): Ditto.
(gst_opt_scheduler_iterate): Ditto.
I understand the opt scheduler now, yippee!

(gst_pad_get_formats_default, gst_pad_get_formats): Better
argument checks, and some doc fixes.
(gst_pad_custom_new_from_template): Um, does anyone
use these functions? Actually make a custom pad instead of a
normal one.
(gst_pad_try_set_caps): Transpose some checks.
(gst_pad_try_set_caps_nonfixed): Same, and use a macro to check if
the pad is in negotiation.
(gst_pad_try_relink_filtered): Use pad_link_prepare.
* gst/gstelement.c: Remove prototypes also defined in gstclock.h.
* gst/gstelement.h:
* gst/gstclock.h: Un-deprecate the old clocking API, as discussed
on the list.
