2704fdaa59 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

dec8139e65 gl/calayer: provide the exact GL api version for the wrapped context 
Otherwise we could end up being mistaken for the diference between a
gl3 and a gl2 context resulting in a failure getting the list of
extensions from the wrapped context due to the difference between
glGetString and glGetStringi for the GL_EXTENSIONS token.

1a98face84 gl: win32: do not call SetParent in release_parent_win_id() 
When called from gst_gl_window_win32_close(), internal window
could not exist, and if it does it's going to be destroyed just
after that anyway. Also it causes window_proc() to be called
and crash because it gets a NULL context.

When called from gst_gl_window_win32_set_window_handle() we are
going to set another parent anyway, and it's probably better to
reparent directly instead of passing by a NULL parent which could
cause the internal window to popup briefly.

247697ce62 gl: win32: fix crash when finalizing GstGLContext 
gst_gl_context_finalize() is calling gst_gl_window_win32_quit()
which was posting a message. But then window_proc takes window's
context and get a NULL.

Now that we've got a GMainLoop we can do like other backends and
simply call g_main_loop_quit().

This also remove duplicated code to release the parent window and
potential crash there because parent_proc could be NULL if we never
created the internal window. That could happen for example if setting
state to READY then setting a window_handle, and go back to NULL state.

e24bc348bd gl: win32: use a GMainContext to dispatch win32 messages 
gst_gl_window_win32_send_message_async() could be called before the
internal window is created so we cannot use PostMessage there.

x11 and wayland backends both create a custom GSource for this,
so there is no reason to not do that for win32.

Also even if we wanted to claim to be live, that wouldn't work well as we
would have to return GST_STATE_CHANGE_NO_PREROLL when going from READY to
PAUSED, which we can't. We first need data to know if we are "live" or not.

66b01c9a0c adaptivedemux: do not try to advance fragment if there is none 
It might return OK from subclasses and it could cause a bitrate
renegotiation. For DASH and MSS that is ok as they won't expose
new pads as part of this but it can cause issues for HLS as
it will expose new pads, leading to pads that will only have EOS
that cause decodebin to fail

802a29eb48 videoaggregator: Check if there's a previous buffer to 'keep' 
If we want to keep a previous buffer but there's no previous buffer, we actually
need more data instead.

14ac40f106 gl/dispmanx: surfaceless EGL context support 
Show the DispmanX window only if there's no shared external GL context
set up. When a window is required by the context a transparent
DispmanX element is created and later on made visible by the ::show
method.

d925e7fd19 glupload: move meta-data copy into gst-gl library 
In some upload implementations the out buffer has more than one references,
turning the buffer not writable, so it won't be possible to modify its
meta-data.

This patch moves the meta-data copy before increasing the reference of the out
buffer.

GL_EXT_texture_rg doesn't take sized formats for the internalformat
