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.

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

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.

da73b89200 element: Add API to more easily post messages about flowing issues
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

b2f9808722 Add support for Meson as alternative/parallel build system

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Mathieu Duponchelle <mathieu.duponchelle@opencreed.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

2) getting the offset (and pts/dts) at the last discont

67ae0ad225 adapter: Add methods to query current offset
API: gst_buffer_prev_offset
API: gst_buffer_get_offset_from_discont

The gst_buffer_get_offset_from_discont() method allows retrieving the current
offset based on the GST_BUFFER_OFFSET of the buffers that were pushed in.

The offset will be set initially by the GST_BUFFER_OFFSET of
DISCONT buffers, and then incremented by the sizes of the following
buffers.

The gst_buffer_prev_offset() method allows retrievent the previous
GST_BUFFER_OFFSET regardless of flags. It works in the same way as
the other gst_buffer_prev_*() methods.

8177173db0 element: Add gst_element_call_async()
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.

This is a useful function to automatically add ghost pads when linking
two elements across bin boundaries without know their exact parentage.

e.g. when using gst_parse_bin_from_description (with or without it ghosting pads),
one can simply retreive the src/sink pads from the bin to link to another pad.

Similar functionality is provided by gst_element_link_pads{_full}() however only
by pad name rather than by actual pads.

8b88fc487f gst.h: Don't spew warnings if GST_USE_UNSTABLE_API is not defined
Only hide GstTracer and GstTracerRecord API behind GST_USE_UNSTABLE_API,
but don't spew any warnings, otherwise everyone has to define this
to avoid compiler warnings.

This reverts parts of commit 89ee5d948d.

10b78d872b tracerrecord: add a log record class
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.

Add docs for the new class and basic tests.

Remove the previous log handler.

347734e529 info: expose debugging printf functions
Other gst libraries and/or elements may want to add some debug logging to an
external debug system or implement delayed debugging for performance reasons.

Exposes the internal __gst_vasprintf as gst_info_vasprintf which has a fallback
to g_vasprintf if the debug system is disabled.

d5ded15889 bin: implement context propagation when adding elements
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.
