bcce615263 gl: add a scary note about initializing thread support for the winsys
We cannot do it as the winsys may crash if we initialize too late.

Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts.  These GL contexts are generally
accessed from different threads.  Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur.  This concurrent access could result in crashes or abortion
by the winsys (xcb).

5433010ab5 gl/wayland: create a dummy display instead of an EGLDisplay
Currently, GstGLWindowWaylandEGL holds the wayland display connection
If we create the EGLDisplay at the GstDisplay creation time, then
libEGL will internally open another connection to the wayland server.
These two display connections are unable to communicate resulting in
no window output/display and hangs inside libEGL.

Eventually we will move the wl_display from GstGLWindow to GstGLDisplay.

320ceef471 gl/display: check the correct env variable for choosing an egl display
GST_GL_WINDOW is used for window system specific choices.
An EGLDisplay can be created from window systems with egl support by using
eglGetDisplay().

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream

303b77eeff [890/906] x11: add display subclass
GstGLDisplayX11 holds the display connection and name.  Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads().  Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.

The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl).  In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.

db236c510f [633/906] display: fail properly in context creation in order to minimize a race condition
previously, on context creation, when we failed to get a valid context
we would still atempt to run the window mainloop as well as setting an error
on the display. This would cause the calling element to finalize the display
and therefore attempt to quit the window mainloop.  However the mainloop
may not have started running.  Thus when the window mainloop ran it would
never a get a quit message and never end.
