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.
Add convenience API that iterates over all pads, sink pads or
source pads and makes sure that the foreach function is called
exactly once for each pad.
This is a KISS implementation. It doesn't use GstIterator and
doesn't try to do clever things like resync if pads are added
or removed while the function is executing. We can still do that
in future if we think it's needed, but in practice it will
likely make absolutely no difference whatsoever, since these
things will have to be handled properly elsewhere by the element
anyway if they're important.
After all, it's always possible that a pad is added or removed
just after the iterator finishes iterating, but before the
function returns.
This is also a replacement for gst_aggregator_iterate_sink_pads().

In many parts of the code we raise streaming error when the flow
goes wrong, and each time we create more or less similare error
message. Also that message does not let the application know what
has actually gone wrong. In the new API we add a "flow-return" detail
field inside the GstMessage so that the application has all the information
if it needs it.
API:
GST_ELEMENT_FLOW_ERROR

Fixes g-i warning "Gst: Constructor return type mismatch
symbol='gst_element_message_new_details' constructed='Gst.Element'
return='Gst.Structure'".
This is a newly-added function in git that has not been in a stable
release yet, so it's fine to rename it. It's also only used indirectly
via macros.
In some corner cases, the error 'code' part passed to
GST_ELEMENT_ERROR() is a valid define as well, in which
case it won't survive two levels of macro expansion, but
only one. Fixes:
oss4-sink.c: In function ‘gst_oss4_sink_open’:
error: ‘GST_RESOURCE_ERROR_0x00000002’ undeclared (first use in this function)
GST_ ## domain ## _ERROR_ ## code, __txt, __dbg, __FILE__,
which is from GST_ELEMENT_ERROR(el,RESOURCE,OPEN_WRITE,..)
and OPEN_WRITE happens to be defined to 2 here.

This calls a function from another thread, asynchronously. This is to be
used for cases when a state change has to be performed from a streaming
thread, directly via gst_element_set_state() or indirectly e.g. via SEEK
events.
Calling those functions directly from the streaming thread will cause
deadlocks in many situations, as they might involve waiting for the
streaming thread to shut down from this very streaming thread.
This is mostly a convenience function around a GThreadPool and is for example
used by GstBin to continue asynchronous state changes.

having to deal with it in a non-application thread.

Pretty much every single element does
gst_element_class_add_pad_template (element_class,
gst_static_pad_template_get (&some_templ));
which is both confusing and unnecessary. We might just
as well add a function to do that in one step.

When adding an element to a bin we need to propagate the GstContext's
to/from the element.
This moves the GstContext list from GstBin to GstElement and adds
convenience functions to get the currently set list of GstContext's.
This does not deal with the collection of GstContext's propagated
using GST_CONTEXT_QUERY. Element subclasses are advised to call
gst_element_set_context if they need to propagate GstContext's
received from the context query.

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.

and remove all the printf extension/specifier stuff for
the system printf. Next we need to add back the custom
specifiers to our own printf implementation.

Elements should override GstElement::set_context() and also call
gst_element_set_context() to keep this context up-to-date with
the very latest context they internally use.
Add gst_element_class_{add,set}_metadata() variants for static strings,
so we can avoid unnecessary g_strdup()s.
API: gst_element_class_add_static_metadata()
API: gst_element_class_set_static_metadata()
There are many good use cases for GstIndex and we want
to add it back again in some form, but possibly not with
the current API, which is very powerful (maybe too powerful),
but also a bit confusing. At the very least we'd need to
make the API bindings-friendly.
