c5b5ef16d3 gl: GST_EXPORT -> GST_GL_API 
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

1784f62895 gl/wayland: Memory leak when display couldn't connect 
When trying to create a wayland display, it may fail because there
is not actually display to connect. It this case NULL is returned
but the created instance is not freed.

This patch unrefs the failed display.

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.

a5aff145a2 gl/wayland: call eglTerminate() before wl_display_disconnect() 
Calling these two functions in the wrong order will result in
use-after-free inside wayland.

4be04f8315 gl: don't export symbols that are not supposed to be public 
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).

f532e699df gl/window: remove use of main_context_push/pop_thread_default() 
No-one's using/depending on it (it would have criticalled and not worked)
and it's causing more problems than it's solving.  Store the GMainContext
in the public struct instead for subclasses to optionally use instead of
relying on the push/pop state to be correct.

2763baf439 gl/wayland: use multi-threaded safe event wayland API 
Multiple threads may be accessing the wayland fd at the same time which
requires the use of special wayland API to deal with to ensure nobody

63bbe9406a glwindow: add API to request a resize event on the next draw 
- glimagesink needs to be able to resize the viewport on aspect ratio
  changes resulting from either caps changes or 3d output mode changes.
- Performing a glViewport outside the GstGLWindow::resize callback
  will not have the winsys' stack of viewports required to correctly
  place the output frame.

Provide a function to request a resize on the next draw event from the
winsys.

Also track size changes inside the base GstGLWindow class rather
than in each subclass.

9f704d7c2d gl/wayland: add GstGLDisplayWayland 
Simple implementation split from GstGLWindowWayland

Can now have multiple glimagesink elements all displaying output
linked via GL or otherwise (barring GL platform limitations).

The intel driver is racy and can crash setting up the two glimagesink contexts.

e.g.
videotestsrc ! tee name=t ! queue ! glupload ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

videotestsrc ! glupload ! glfiltercube ! tee name=t ! queue ! glimagesinkelement
  t. ! queue ! gleffects_blur ! glimagesinkelement

019367c128 glwindow: remove width/height from _draw() 
Depending on the platform, it was only ever implemented to 1) set a
default surface size, 2) resize based on the video frame or 3) nothing.
Instead, provide a set_preferred_size () that elements/applications
can use to request a certain size which may be ignored for
videooverlay/other cases.
