5f70adf667 gl/egl/display: Add support EGLDevice display type 
Simple addition for supporting EXT_platform_device typed display.
It's a kind of special display type (part of EGL specification)
which has no window at all.
To use EGLDevice explicitly, set environment "GST_GL_WINDOW=egl-device"

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.

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.

4df219f336 gl: Add Mesa3D GBM backend 
This makes it possible to use the GStreamer OpenGL elements without a
windowing system if a libdrm- and Mesa3D-supported GPU is present

4952fdd956 gl: do not include GL headers in public gstgl headers 
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

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.
