This is something bindings can't handle and it causes leaks. Instead
move the ref_sink() to the explicit, new() constructors.
This means that abstract classes, and anything that can have subclasses,
will have to do ref_sink() in their new() function now. Specifically
this affects GstClock and GstControlSource.

Use g_object_new() instead which nowadays has a shortcut for the
no-properties check. It still does an extra GType check in the
function guard, but there's a pending patch to remove that
and it's hardly going to be a performance issue in practice,
even less so on a system that's compiled without run-time checks.
Alternative would be to move to the new g_object_new_properties()
with a fallback define for older glib versions, but it makes the
code look more unwieldy and doesn't seem worth it.
Fixes deprecation warnings when building against newer GLib versions.

If guessing that a string matches a flagset, be more thorough
at checking that the string following a string of hex:hex:
actually looks like a flag set string. Add some unit tests
to catch more cases.

We would add the offset a second time in _scan_for_start_code()
when we found a result, but it's already been added to the data
pointer at the beginning of _masked_scan_uint32_peek(), so the
peeked value would be wrong if the initial offset was >0, and
we would potentially read memory out-of-bounds.
Add unit test for all of this.

The unit test defines a test parse element that inherit from GstBaseParse.
The test pipeline is: fakesrc ! testparse ! fakesink sync=1
Before the fix b2c05cac8 the first new test would have fail because the
pipeline would have wait doing nothing just after proceeded the seek event.
The second new test would have fail because the pipeline would have
played the media instantly just after proceeded the seek event
(like if sync was FALSE on the sink).

Allows proper usage of structures in structures in caps. Subtraction
is not implemented due to complications with empty fields representing
all possible values.
The only implementation that doesn't delegate to the already existing
GstStructure functions is the union function.

As an usecase of URI fragment, it can indicate temporal or spatial
dimension of a media stream. To easily parse key-value pair,
newly added gst_uri_get_media_fragment_table () API will provide
the table of key-value pair likewise URI query.

This structure is always allocated by GStreamer, can't be
subclassed or extended, and is never allocated or used on
the stack, so we don't need any padding and can extend it
as we please.
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.

Add unit test to ensure that.
It can be a normal execution path to do some map trials and there is
no need to worry the user in that case.
The application has to check the return value of gst_memory_map.

Introduce a new operator ':' - e.g. element1 ':' element2
For example, 'uridecodebin : encodebin' -
if the encodebin has multiple profiles compatible with the
decodebin, multiple links will be created.
With '!' , after one delayed link is successfully done, the
pad-added callback is disconnected.

This carries over code for a similar test from multiqueue to ensure full
control over the dataflow while testing. (The previous attempt was racy
since the fill level changed without any thread sync with the test code.)
https://bugzilla.gnome.org/show_bug.cgi?id=771210
Basically we already have each test with a 20sec timeout,
and testsuite can last more than the default 30secs from
meson. 3 minutes is another arbitrary timeout but should
be good enough.
low/high-watermark are of type double, and given in range 0.0-1.0. This
makes it possible to set low/high watermarks with greater resolution,
which is useful with large multiqueue max sizes and watermarks like 0.5%.
Also adding a test to check the fill and watermark level behavior.

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/2016/05/gstreamer-and-meson-new-hope.htmlhttp://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.
A new event which precedes EOS in situations where we
need downstream to unblock any pads waiting on a stream
before we can send EOS. E.g, decodebin draining a chain
so it can switch pads.

Redirection messages are already used in fragmented sources and in
uridecodebin, so it makes sense to introduce these as an official message
type.

We don't do calculations with different units (buffer offsets and bytes)
anymore but have functions for:
1) getting the number of bytes since the last discont
2) getting the offset (and pts/dts) at the last discont
and the previously added function to get the last offset and its distance from
the current adapter position.
https://bugzilla.gnome.org/show_bug.cgi?id=766647
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.
https://bugzilla.gnome.org/show_bug.cgi?id=766647
It is better to have separate tests:
1) the test name will tell what is broekn when the test fails
2) we still run the other tests when one assert fails
3) the tests are easier to understand
4) we don't rely on sie effect of previous actions
5) ...
Also ix the assertion message for the name checks (Gst -> fakeobject).
GObject allow calling g_object_notify() within set_property() and
won't notify it twice. As it was raised during review, add a unit test to
make sure.

This means applications and bin sub-classes can easily track when
a new child element is added to the pipeline sub-hierarchy or
removed.
Currently doesn't signal deep added/removed for elements inside
a bin if a bin is added/removed.
https://bugzilla.gnome.org/show_bug.cgi?id=578933
gst_check_setup_sink_pad() internally uses gst_check_chain_func() so we
should call gst_check_drop_buffers() when tearing down tests to free the
buffers which have been exchanged through the pipeline.
https://bugzilla.gnome.org/show_bug.cgi?id=765903
The test rely on bus being flushed when setting the bin to the NULL state which
is not the case. This apply only when setting the pipeline state to
NULL.

This ensures the following special case is handled properly:
1. Queue is empty
2. Data is pushed, fill level is below the current high-threshold
3. high-threshold is set to a level that is below the current fill level
Since mq->percent wasn't being recalculated in step #3 properly, this
caused the multiqueue to switch off its buffering state when new data is
pushed in, and never post a 100% buffering message. The application will
have received a <100% buffering message from step #2, but will never see
100%.
Fix this by recalculating the current fill level percentage during
high-threshold property changes in the same manner as it is done when
use-buffering is modified.

We need to clear some global state and register a new test
basetransform subclass for each test because we do things
in class_init base on global state.

The test assumed that if a buffer has the same pointer address as
before it is in fact the same mini object and has been re-used by
the pool. This seems to be mostly true, but not always. The buffer
might be destroyed and when a new buffer is created the allocator
might return the same memory that we just freed.
Instead attach a qdata with destroy notify function to buffer
instances we want to track to make sure the buffer actually
gets finalized rather than resurrected and put back into the pool.
Be notified in the application thread via bus messages about
notify::* and deep-notify::* property changes, instead of
having to deal with it in a non-application thread.

Checking the current element's state when we're adding pads to
the parent element is checking the wrong thing.
Silences a 'attempting to add an inactive pad to a running element'
warning when adding a ghost pad to a running parent bin of the parent
bin of the element.
