Except for gst/gl/gstglfuncs.h
It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.
For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.
For example with this patch, if an app includes the headers
gst/gl/egl/gstglcontext_egl.h
gst/gl/egl/gstgldisplay_egl.h
gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.
Also added a test: cd tests/check && make libs/gstglheaders.check

Scenario:
A manifest starts out in live mode but then the recording is finalized
and a subsequent update changes the state to a non-live manifest when
the server has finished recording/transcoding/whatever with the full
list of fragments.
Without this patch, the manifest update task is never stopped on the
live->non-live transition and will busy loop, burning through one CPU
core.

Make a bunch of symbols private that are currently leaked
accidentally because they have a gst_* prefix and are used
internally. We mark those we can't make static with
G_GNUC_INTERNAL so that they get hidden with the autotools
build as well (although we could just pass -fvisibility=hidden
there too).
The goal here is to minimize the work needed to bring all images
to a common format. A better criteria than the number of pads
with a given format is the number of pixels with a given format.

This commit ensures that the idle probe which GstAdaptiveDemuxStream
adds to the upstream source pad is removed after use. Previously a new
probe was added to the pad whenever a fragment was downloaded, meaning
the number of pad probe callbacks being executed increased continually.

There can be twice as many stream tasks running as there are output
pads for playback of variant HLS playlists. Half of them are the
current pads, and the other half are the pads that are about to be
switched to due to a bitrate change.
The old code only stopped the current streams which could result
in a deadlock on stopping the pipeline. The changes force stopping
and joining of any prepared streams too.

Crossfading is a bit more complex than just having two pads with the
right keyframes as the blending is not exactly the same.
The difference is in the way we compute the alpha channel, in the case
of crossfading, we have to compute an additive operation between
the destination and the source (factored by the alpha property of both
the input pad alpha property and the crossfading ratio) basically so
that the crossfade result of 2 opaque frames is also fully opaque at any
time in the crossfading process, avoid bleeding through the layer
blending.
Some rationnal can be found in https://phabricator.freedesktop.org/T7773.

Found on rpi when gpu_mem is too low so there is not enough memory to
create the eglimage. But still gst_buffer_pool_acquire_buffer succeeded.
And it leads to a CRITICAL assert:
gst_egl_image_get_image: assertion 'GST_IS_EGL_IMAGE (image)' failed
https://bugzilla.gnome.org/show_bug.cgi?id=785518
Otherwise check_events() will not remove the GAP event (as the queue
tail is not the event anymore but the GAP buffer), then the GAP buffer
is handled, then the GAP event is handled again, ... forever.
Avoids dereferencing dead objects
What happens in the autovideosink case is that context 1 is created and
destroyed before all the async operations hae executed on the associated
window. When the delayed operations execute, they then reference dead
objects and crash.
We fix this by keeping refs over all async operations so the object
cannot be deleted while async operations are in flight.

This is a workaround for a regression introduced by
f4190a49c0
( adaptivedemux: Check live seeking range more often )
The goal of the previous commit was to be able to cope with non-1.0
rates on live streams which have a "seeking window" (i.e. the server
keeps around quite a bit of the live stream so you can seek back into
it).
Without that commit, two different kind of issues would happen:
* When doing reverse playback, you would never check whether you
are outside of the seekable region. And would then continuously
try to download fragments that are no longer present.
* When doing fast forward, you would end up requesting fragments
which are not present yet.
In order to determine whether one was *really* outside of the seekable
window, we check whether the current stream position is still
within the seekable region.
The *problem* though with that commit is that it assumes that subclasses
will return continuously updated seeking ranges (i.e. dependent on the
current time), which is *NOT* the case.
For example:
* dashdemux does use the current UTC to determine the seekable region
* hlsdemux uses the values from the last updated manifest
Therefore if one downloads fragments faster than realtime, for HLS
we would end up at the end of the last manifest seekable range, and
the previous commit would consider the stream as being ended... which
is not the case.
In the long run, we need to figure out a way to cope with non-1.0
rates on live streams for all types of stream (including HLS).
