Should reproduce 'GStreamer-WARNING **: wrong STREAM_LOCK count 0'
warnings (with make pipelines/seek.torture or pipelines/seek.forever
anyway, since it appears to be racy).

Account for rounding errors in some places, and that two nows are
not always entirely identical, so allow some leeway when comparing
microseconds and seconds. Ran into this too often, esp. when the
system is under load.
The internal proxy pad target is simply a cache of the internal proxy pad
peer. This patch uses the well implement GstPad peer handling to obtain the
target. This fixes issues with target not being set in both direction when
two ghostpads are linked together (empty bin).

It's only used internally anyway and the helper struct
has namespace issues.
API: deprecated gst_plugin_feature_type_name_filter()
API: deprecated GstTypeNameData
..and as a result gst_caps_is_equal() and others.
This now only checks if for every subset structure there is
a superset structure in the superset caps. Previously we were
subtracting one from another, creating completely new caps
and then even simplified them.
The new implemention now is about 1.27 times faster and doesn't
break the -base unit tests are anything anymore.
API: gst_mini_object_weak_ref()
API: gst_mini_object_weak_unref()
Add weak referencing functionality to GstMiniObject, which
allows to get notifications when an mini object is destroyed
but doesn't increase the real refcount. This is mostly
useful for bindings.
Fixes bug #609473.
This allows to get the internal pad of ghostpads and
proxypads without using gst_pad_iterate_internal_links()
and is much more convenient.
The internal pad of a ghostpad is the pad of the opposite direction
that is used to link to the ghostpad target.
This prevents adding duplicates over and over again to the resulting
caps if they already describe the new intersection result.
While this changes intersection from O(n*m) to O(n^2*m), it results in
smaller caps, which in the end will decrease further processing times.
For example in an audioconvert ! audioconvert ! audioconvert pipeline,
when forwarding the downstream caps preference in basetransform
(see e26da72de25a91c3eaad9f7c8b2f53ba888a0394) this results in
16 instead of 191 caps structures.
Currently fails (in normal circumstances) because we create a
socket pair for each bin's bus and exhaust the number of available
file descriptors.

Adding a buffer to the end of a GstBufferList is supposed to be a fast
operation, but it was not since the iterator does not advance its
nextpointer when adding buffers and GList does not have a tail pointer.
Using a GQueue to store the buffers makes it easier to add buffers to
the end of the list and this operation will now be much more efficient.
Adding an entire GList of buffers using
gst_buffer_list_iterator_add_list() will however have to iterate over
the list being added to be able to update the tail pointer in the
GQueue.
