Tim-Philipp Müller 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.

Stefan Sauer 89ee5d948d tracer: add a GFlag for the tracer scope 
Port all tracers. Add the GST_USE_UNSTABLE_API flag to the internal CFLAGS so
that we don't have to specify this for gir, docs, mkenum, ...

Stefan Sauer 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.

Fixes #760267

Matthew Waters 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.

API: gst_info_vasprintf
API: gst_info_strdup_vprintf
API: gst_info_strdup_printf

Edward Hervey 41e1bea7ef buffer: Add a GST_BUFFER_DTS_OR_PTS macro 
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

Vineeth TM 215cfcf993 gstreamer: Fix memory leaks when context parse fails 
When g_option_context_parse fails, context and error variables are not getting free'd
which results in memory leaks. Free'ing the same.

And replacing g_error_free with g_clear_error, which checks if the error being passed
is not NULL and sets the variable to NULL on free'ing.

Matthew Waters 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.
