3d5c849a6c identity: Add a stats property
This is inspired by the stats on rtpjitterbuffer, it's useful
to be able to get some simple stats out of the pipeline without having
to write yet another pad probe.

cb212c9fd7 identity: Handle seeking with single_segment=True
Identity was ignoring seek and flush events even when using
a single segment. In the end it means that we couldn't compute
buffers running-time and stream time after seeks.

This commits adds support for flushing seeks only as I have no idea
what to do for non flushing ones.

63170d52ae identity: fixes to the eos-after and error-after properties
I copied `error-after` to make the `eos-after` property, but it turned
out there were some problems with that one, so this patch: adds
separate counters (so setting to NULL and reusing the element will
still work); clarifies the properties' min values; and reports an
error when both are set.

460c0edbfb identity: add eos-after property
Using `num-buffers` can be unpredictable as buffer sizes are often
arbitrary (filesrc, multifilesrc, etc.). The `error-after` property on
`identity` is better but obviously reports an error afterwards. This
adds `eos-after` which does exactly the same thing but reports EOS
instead.

2cc5c539a3 identity: Add a drop-allocation property
When enabled, this property will make the allocation query fail. This is
the same as one could have done using a tee before the tee started
implementing the allocation query.

82ed369991 identity: Return FLUSHING instead of EOS and don't start waiting for anything if currently flushing
Otherwise we might try unscheduling a clock id (that does not exist
yet), then the streaming thread waits for id and the state change never
continues because the streaming thread is blocked.

Also shutting down and flushing and similar should return FLUSHING, not
EOS. The stream is not over, we're just not accepting any buffers
anymore.

Use more efficient g_object_notify_by_pspec() if we're compiling against
GLib >= 2.26, and also remove work-around for g_object_notify() thread-
safety issues with older GLib versions if it's not needed any more.

d9df74ea3e identity: hack around g_object_notify() bug by protecting it with a lock
Out-of-band events might lead to us calling g_object_notify() from a
non-streaming thread, which can cause crashes if g_object_notify() is
being called from the streaming thread at the same time. See #554460.

Original commit message from CVS:
2005-07-01  Andy Wingo  <wingo@pobox.com>

* 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.
