Custom meta is backed by a GstStructure, and does not require
that users of the API expose their GstMeta implementation as
public API for other components to make use of it.
In addition, it provides a simpler interface by ignoring the
impl vs. api distinction that the regular API exposes.
This new API is meant to be the meta counterpart to custom events
and messages, and to be more convenient than the lower-level API
when the absolute best performance isn't a requirement.

Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).
* Making sure that `static inline` function are in the GIR (by first
defining them, and make sure to mark as skiped)
* Do not try to link to unexisting symbols
* Also generate GIR information about gst_tracers
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
This can be used to identify buffers for which a higher percentage
of redundancy should be allocated when performing forward error
correction, or to prevent still video frames from being dropped by
elements due to QoS.

This is a meta that generically allows to attach additional reference
timestamps to a buffer, that don't have to relate to the pipeline clock
in any way.
Examples of this could be an NTP timestamp when the media was captured,
a frame counter on the capture side or the (local) UNIX timestamp when
the media was captured.

The alias define GST_TYPE_PARENT_BUFFER_META_API_TYPE is wrong and
breaks the usage of gst_buffer_get_parent_buffer_meta().
This patch fixes the GType alias and make another alias to keep the API
compatibility guarded by GST_DISABLE_DEPRECATED.
Also added a unit test.

There is a similar explanation in gst_caps_make_writable, but the existing
documentation can be misleading since it does not define what 'is already
writable' means.
Also note when this function is meant to be used.
API: GST_BUFFER_DTS_OR_PTS
Many scenarios/elements require dealing with streams of buffers that
might have DTS set (i.e. encoded data, potentially reordered)
To simplify getting the increasing "timestamp" of those buffers, create
a macro that will return the DTS if valid, and if not the PTS
A core meta which helps implement the old concept
of sub-buffering in some situations, by making it
possible for a buffer to keep a ref on a different
parent buffer. The parent buffer is unreffed when
the Meta is freed.
This meta is used to ensure that a buffer whose
memory is being shared to a child buffer isn't freed
and returned to a buffer pool until the memory
is.

There was few Since: mark missing their column. Also unify the way
we set the Since mark on enum value and structure members. These
sadly don't show up in the index.
A variant of gst_buffer_copy that forces the underlying memory
to be copied.
This is added to avoid adding an extra reference to a GstMemory
that might belong to a bufferpool that is trying to be drained.
The use case is when the buffer copying is done to release the
old buffer and all its resources.

* fix typo GstBufferFlag -> GstBufferFlags
* fix typo GstFeatures -> GstCapsFeatures
* fix typo GstAllocatorParams -> GstAllocationParams
* fix typo GstContrlSources -> GstControlSource
* do not refer to gstcheck as an object
* make references gtk_init() and tcase_set_timeout() not be references
* gst_element_get_pad() renamed gst_element_get_static_pad()
* gst_clock_id_wait_async_full() renamed gst_clock_id_wait_async()
* _drop_element() is really gst_queue_array_drop_element()
* gst_pad_accept_caps() was removed, do not refer to it
* separate GST_META_TAG_MEMORY_STR declaration from description
* do not describe removed gst_collect_pads_collect()
* correctly link to GstElementClass' virtual set_context()

GObject Introspection does not support macros.
This is needed for bindings. We can still add back
macros or inline functions again later if we think
it's worth it.
https://bugzilla.gnome.org/show_bug.cgi?id=678301
Make GstAllocator a GstObject instead of a GstMiniObject, like bufferpool.
Make a new gstallocator.c file. Make a GstAllocator subclass for the default
allocator.
