Make default message forwarding from child->bus to bin->bus
threadsafe and make it not emit warnings if the parent has no bus.

* gst/elements/gstcapsfilter.c: Reimplement using basetransform,
fixes buffer_alloc proxying among other things.
* gst/base/gstbasetransform.c:
* gst/base/gstbasetransform.h:
Revert patch to gstbasetransform from 7-28 removing
delay_configure.
* gst/base/gstbasetransform.h (GstBaseTransformClass.get_size):
* gst/base/gstbasetransform.c (gst_base_transform_get_size):
Semantics changed, should return not the size of the output buffer
but the byte size of a buffer with a given caps.
* gst/base/gstbasetransform.c (gst_base_transform_getcaps): Better
debug object.
(gst_base_transform_configure_caps): Don't set out_size here: (in,
out) are not the pad caps until setcaps finishes.
(gst_base_transform_buffer_alloc): Proxy the buffer_alloc for the
not-in-place case as well. Deal with changing from in-place to
not-in-place within calling pad_alloc_buffer. Still a bit
concerned about the overhead here...
Original commit message from CVS:
* gst/base/gstcollectpads.c: (gst_collectpads_finalize),
(gst_collectpads_stop):
Broadcast the condition when shutting down, to make sure we wake all
threads up. Shut down pads on finalize, for safety.

sort of a last resort, and use profile-based fixation first, but
since that doesn't exist yet, this is the best we have. Fixes

* tests/network-clock.scm: Commentary update.
* gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone.
Didn't really make sense, not implementable with basetransform,
etc.
(gst_identity_transform): Unref inbuf via make_writable. Feeble
attempt at implementing the sync property, needs an unlock method.
* gst/base/gstbasetransform.c (gst_base_transform_transform_caps):
New func, by default returns the same caps (the identity
transformation).
(gst_base_transform_getcaps): Uses transform_caps to return
something sensible.
(gst_base_transform_setcaps): Complicated logic to get caps on
both pads, even if they are different, and to call set_caps once
for every time both pads get their caps set.
(gst_base_transform_handle_buffer): Give the ref to the transform
function. Allows in-place modification of the buffer.
* gst/base/gstbasetransform.h (transform_caps): New class method.
Given caps on one side, what can I do on the other.
(set_caps): Take two caps, one for each side of the element.
* gst/gstpad.h:
* gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify
caps in place. This is safe because we can check the mutability of
the caps, and a good idea because fixate functions are just called
as a matter of last resort. (Not actually implemented.)
(gst_pad_set_caps): If the caps we're setting is actually the same
as the existing pad caps, just update the pointer without calling
setcaps. Assert that caps is either NULL or fixed, as per the
docs.
* gst/gstghostpad.c: Update for fixate changes.

help in debugging.

* gst/gstghostpad.c (on_int_notify): Catches notify::caps on the
internal pad, and hacks accordingly. Doesn't do it on the target
pad because we change its caps. Probably catches all cases of
interest tho.
(gst_ghost_pad_set_property): Connect to notify::caps as
appropritate.

Original commit message from CVS:
* check/gst/gstvalue.c: (START_TEST), (gst_value_suite):
* gst/gstvalue.c: (gst_value_deserialize_int_helper):
remove gst_strtoll completely, since it didn't actually do
anything more than what g_ascii_strtoull already does.
check for range errors when deserializing
do a cast for the unsigned cases; but further fixing needs
a decision on what the interpretation of "(int)" and
deserialization should be for values that fall outside the
type's boundaries (ie, refuse, or interpret as casting)
Original commit message from CVS:
Added support for live sources and other elements that
cannot do preroll.
Updated design docs, added live-source design doc.
Implemented live source functionality in basesrc
Fix error condition in _bin_get_state()
Implement live source handling in -launch.
Added check for live sources.

gst_pad_set_caps on the target, not just its setcaps() function.
Original commit message from CVS:

* gst/gststructure.h:
add a way to get the name of a field referenced by index
* gst/gstvalue.c: (gst_value_deserialize_int_helper):
instead of checking if the resulting long long lies between
min and max, we check if the long long would fit into
a number of bytes for the final type.
This fixes cases where a string represents 2^32 - 1, which
when cast to int would be the (valid) -1, but is bigger than
G_MAXINT
Original commit message from CVS:
* check/gst/gstvalue.c: (START_TEST):
* gst/gstvalue.c: (gst_value_deserialize):
return long long, not int, so gint64 deserialization actually
works. Is there any flag that makes the compiler check this ?

whitespace removal
Original commit message from CVS:
2005-06-17 Andy Wingo <wingo@pobox.com>
* gst/base/gstbasesink.c (gst_basesink_chain): Remove bogus
assert; it's always possible that the pad gets deactivated in
between the checks in gstpad.c and the implementation. Rely on
finish_preroll() to return a FLUSHING or similar instead of on the
assert.
Original commit message from CVS:
2005-06-17 Andy Wingo <wingo@pobox.com>

the playing state.

* gst/gstutils.c: RPAD fixes all around.
(gst_element_link_pads): Refcounting fixes.
* tools/gst-inspect.c:
* tools/gst-xmlinspect.c:
* 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.
Original commit message from CVS:
* gst/elements/gstcapsfilter.c: (gst_capsfilter_set_property):
Free existing caps if the capsfilter changes. Add a FIXME about
setting those caps on the pads.
* gst/gstutils.c: (gst_element_get_compatible_pad), (ghost_up):
Before adding a ghost pad to a parent bin, check that there isn't
already one for the element on the bin. Prevents infinite recursion
when using decodebin in parse pipelines. Andy says he'll rewrite the
way this works anyway, so ignore the hack.

* gst/elements/gsttypefindelement.c (do_pull_typefind): Query the
file size, pass it on to the type find helper.
* gst/base/gstbasesrc.c (gst_basesrc_do_seek): Set the
segment_start and segment_end properly according to the seek
method. Segment_end is still a bit flaky because offset can be
negative for CUR and END cases, but it takes -1 as an "unset"
value.
Original commit message from CVS:
* gst/elements/gstidentity.c: (gst_identity_event),
(gst_identity_transform), (gst_identity_get_property):
Protect last_message property as it is accessed from
