Support for (nullable) was added to G-I at the same time as nullable
return values. Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

Boxed types can't be derived from, and we don't support
deriving from our special fundamental types (the code
checks for GType equality in most places.
* 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

gstutils.c:3659:41: error: format string is not a string literal
[-Werror,-Wformat-nonliteral]
gchar *expanded = g_strdup_vprintf (stream_id, var_args);
https://bugzilla.gnome.org/show_bug.cgi?id=710621
This makes gst_parse_bin_from_description() return an element instead of
a bin if there's only one element. Also changed gstparse.c to use this,
so gst-launch won't create superfluous bins.

All streams that have the same group id are supposed to be played
together, i.e. all streams inside a container file should have the
same group id but different stream ids. The group id should change
each time the stream is started, resulting in different group ids
each time a file is played for example.
This reverts commit 1a1a9e143f.
This breaks the pipelines/tagschecking unit test for some reason
(fakesrc ! capsfilter ! qtmux linking fails now). It might be
a bug in the unit test of course, but someone will need to
investigate this. Reverting for now.

motivation comes from: /* FIXME: why not gst_pad_get_pad_template (pad); */
this code path is quite nicer, we now only revert to creating the template
if gst_pad_get_pad_template fails.
with this fork, we gain a non-allocation of GstCaps *templcaps

We usually first create the stream_id for the stream_start event and then add
the pad to the element. This means that this functions should work when there
are no pads on the element yet.
In the proxy_query_caps function, also filter against the filter in the query.
We don't need to filter against the filter in the query anymore in the default
caps query function because we already did this in the proxy_query_caps.
These changes are to clean up syntax issues such as missing colons,
missing spaces, etc., and minor issues such as argument names in
headers not matching the implementation and/or documentation.
Add gst_buffer_append() which appends the memory blocks from one buffer to
another. Remove the old inefficient _merge() and _join() methods which forced a
premature memcpy in most cases.
Remove the _is_span() and _span() methods they are not needed anymore now that
we can _append(). Merging and spanning will be delayed until mapping or maybe
not at all when the element can deal with the different memory blocks.
Rework some caps operations so they don't rely on writable caps but instead take
ownership of the input caps and do _make_writable() only when needed.
Remove some const from caps functions, it does not make much sense for
refcounted objects and does not allow us to return a refcount to the const input
caps.
Rework the base classes fixate vmethods to not operate on the caps in-place.
All this saves us around 30% of caps and structure copy and new operations.
fix the proxy functions for query_accept_caps and query_caps to use the pad
forward helper functions which correctly forwards on the internally linked pads.
Remove the getcaps function on the pad and use the CAPS query for
the same effect.
Add PROXY_CAPS to the pad flags. This instructs the default caps event and query
handlers to pass on the CAPS related queries and events. This simplifies a lot
of elements that passtrough caps negotiation.
Make two utility functions to proxy caps queries and aggregate the result. Needs
to use the pad forward function instead later.
Make the _query_peer_ utility functions use the gst_pad_peer_query() function to
make sure the probes are emited properly.
The idea was originally that if one passed &dest_fmt with
dest_fmt=GST_FORMAT_DEFAULT, then the code answering the query
could change dest_fmt to the actual default format used. However,
in more than half a decade of GStreamer 0.10 no piece of code in
GStreamer has ever used that feature, nor are there that many
users of this API that actually check whether the format returned
is the original format passed before using the values returned.
Also, it's just annoying-to-use API in its own right.
For all these reasons, make it so that the destination format is
passed directly and can't be changed by the element queried.
Don't mix messages and pads and tags.
Make the sink post tag messages when a tag event is received.
Since tags are sticky on pads now, they can be retrieved from there
when needed.
See #651514 for details. It's apparently impossible to write code
that avoids both type punning warnings with old g_atomic headers and
assertions in the new. Thus, macros and a version check.
This reverts commit cf4fbc005c.
This change did not improve the situation for bindings because
queries are usually created, then directly passed to a function
and not stored elsewhere, and the writability problem with
miniobjects usually happens with buffers or caps instead.
GST_DISABLE_DEPRECATED should only affect visibility of declarations in headers,
not actually remove symbols. See GitDeveloperGuidelines and DeprecatingAPI
pages in wiki.
