eb06907fb4 gl/wayland: provide a dummy global_remove function
Even if we don't care about any global objects being removed, wayland
will still error if globals are removed without a corresponding listener
set up for them.  e.g. wl_output hotplugging

98249a57db gst: don't use volatile to mean atomic
volatile is not sufficient to provide atomic guarantees and real atomics

e762f1b376 Revert "gstgldisplay: Add public foreign_display property"
This introduced a possible regression where the EGL display connection
could be leaked when a foreign native display (x11, wayland, etc) could
create a non-foreign EGL display that would never be destroyed.

The underlying problem needed to be solved in a different way.  See
https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/640
for more details.

This reverts commit 2e686b0dad.

5ae7998a8f gl/wayland: use a proxy wrapper for the wl_display
This allows us to remove races when setting the wl_queue on wayland
objects with wl_proxy_set_queue() as each created object is created with
the queue already set.

We can also move all our initilization code into the window as we
can retrieve all wayland objects from each window instance.  This
removes a possible race when integrating with external API's as we would
always attempt to immediately retrieve a small set of wayland objects.
That is no longer the case with the objects from each window instance.

7b8fc744f1 gl/wayland: fix wayland event source burning CPU
Commit c71dd72b "gl/wayland: fix glib mainloop integration" was overeager
in removing the poll result test from the check function. This caused
dispatch to be called even if no new events are available on the
Wayland connection, which in turn would wake up the glib mainloop,
causing effectively a tight loop without ever blocking on the poll.

Fixes #603

2e686b0dad gstgldisplay: Add public foreign_display property
We use this property in gst_gl_display_egl_from_gl_display, to set
foreign_display for the new GstGLDisplayEGL instance. This fixes a
problem where gst_gl_display_egl_finalize calls EglTerminate on a
pre-existing EGL connection.

92137572c3 egl: wl_egl_window is not wl_proxy
It seems that eglCreatePlatformWindowSurfaceEXT is failing (with
EGL_BAD_ALLOC) because it thinks an EGL surface has already been created
for the wl_egl_window. The reason is that the "driver_private" field of
the wl_egl_window is getting clobbered by the function
wl_proxy_set_queue().

Since a wl_egl_window is not a wl_proxy, it shouldn't be passed to
wl_proxy_set_queue(). It just wraps a wl_surface (which is a wl_proxy).
And it looks like the queue for that surface is getting set earlier on
in the function anyway.

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/621#note_184582

e8450397c0 gl/wayland: Don't prefix wl_shell struct field
As part of commit 808e7127, we prefixed the `GstWlWindow`'s `shell`
field with wl_, to differentiate it from the other types of shells a
Wayland compositor might support. However, this is apparently a struct
that we expose to our users, so changing it means we have an API break.

c71dd72b21 gl/wayland: fix glib mainloop integration
Implement the prepare and check functions according to the
documentation by returning TRUE when events should be dispatched
via the dispatch function.

As wl_display_read_events never blocks we can call it unconditionally
without looking at the poll status.

This simplifies the implementation and gets rid of a race where the
mainloop could get blocked due to nobody actually reading the events
from the wayland connection.

[wl_shell] is officially [deprecated], so provide support for the
XDG-shell protocol should be provided by all desktop-like compositors.

Note that the [XML spec] is provided by the `wayland-protocols`
git repository, which is provided by the Wayland project.

dc29bc4e13 libs: fix API export/import and 'inconsistent linkage' on MSVC
For each lib we build export its own API in headers when we're
building it, otherwise import the API from the headers.

This fixes linker warnings on Windows when building with MSVC.

The problem was that we had defined all GST_*_API decorators
unconditionally to GST_EXPORT. This was intentional and only
supposed to be temporary, but caused linker warnings because
we tell the linker that we want to export all symbols even
those from externall DLLs, and when the linker notices that
they were in external DLLS and not present locally it warns.

What we need to do when building each library is: export
the library's own symbols and import all other symbols. To
this end we define e.g. BUILDING_GST_FOO and then we define
the GST_FOO_API decorator either to export or to import
symbols depending on whether BUILDING_GST_FOO is set or not.
That way external users of each library API automatically
get the import.

While we're at it, add new GST_API_EXPORT in config.h and use
that for GST_*_API decorators instead of GST_EXPORT.

The right export define depends on the toolchain and whether
we're using -fvisibility=hidden or not, so it's better to set it
to the right thing directly than hard-coding a compiler whitelist
in the public header.

We put the export define into config.h instead of passing it via the
command line to the compiler because it might contain spaces and brackets
and in the autotools scenario we'd have to pass that through multiple
layers of plumbing and Makefile/shell escaping and we're just not going
to be *that* lucky.

The export define is only used if we're compiling our lib, not by external
users of the lib headers, so it's not a problem to put it into config.h

Also, this means all .c files of libs need to include config.h
to get the export marker defined, so fix up a few that didn't
include config.h.

This commit depends on a common submodule commit that makes gst-glib-gen.mak
add an #include "config.h" to generated enum/marshal .c files for the
autotools build.

b25413fb1c gl/wayland: move roundtrip on show to window thread
This makes it thread safe and fixes a possible deadlock.

Keeping the roundtrip off the window thread will result in two different
threads call wl_display_dispatch_queue() for the same queue which
violates the assumption for _dispatch_queue()'s thread-safety
guarantees.

Make a bunch of symbols private that are currently leaked

G_GNUC_INTERNAL so that they get hidden with the autotools

there too).
