Matthew Waters 86abf49c23 gst: add a promise object
An object that can be waited on and asked for asynchronous values.
In much the same way as promise/futures in js/java/etc

A callback can be installed for when the promise changes state.

Original idea by
Jan Schmidt <jan@centricular.com>

With contributions from
Nirbheek Chauhan <nirbheek@centricular.com>
Mathieu Duponchelle <mathieu@centricular.com>

Tim-Philipp Müller d106390adc element: add gst_element_foreach_*pad()
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().

folder of the main executable in order to determine the
set of features they will expose, for example:

Xabier Rodriguez Calvar bda8440f1f protection: add function to filter system ids
gst_protection_filter_systems_by_available_decryptors() takes an array
of strings and returns a new array of strings filtered by the available
decryptors for them so the ones you get are the ones that you should be
able to decrypt.

Sebastian Dröge 7d930b8693 buffer: Add GstReferenceTimestampMeta
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.

Thibault Saunier 33616d47be info: Add a 'flags' parametter to gst_debug_get_stack_trace
This is an API break but that API has not been released yet.

We are passing a flag rather than a simple boolean as we can imagine
to implement more features in the future for example to retrieve a
stack trace for all the threads, etc..

Retrieving source file and line numbers is pretty
expensive while getting a stack trace, this new argument
allows the user to decide to retrieve a backtrace
without those infos instead which is much faster.

For example running $ GST_LEAKS_TRACER_STACK_TRACE=1 GST_DEBUG=GST_TRACER:7 \
GST_TRACERS=leaks time gst-launch-1.0 videotestsrc num-buffers=1 ! fakesink:

* With simple stack traces:

    0.04s user 0.02s system 99% cpu 0.060 total

* With full stack traces:

    0.66s user 0.23s system 96% cpu 0.926 total

Matthew Waters 3eb4896435 controllers: add new proxy control binding
Allows proxying the control interface from one property on one GstObject
to another property (of the same type) in another GstObject.

E.g. in a parent-child relationship, one may need to
gst_object_sync_values() on the child and have a binding (set elsewhere)
on the parent update the value.

Note: that this doesn't solve GObject property forwarding and must be
taken care of by the implementation manually or using GBinding.
