Julien Isorce 2fd84a6c86 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

--- Description of the generic (no GUI) examples ---

- cube:
Show how to have a graphic FPS greater than the input video frame rate.
The source is the videotestsrc rgb.

- cubeyuv:
Show how to have a graphic FPS greater than the input video frame rate.
The source is a local video file needed in argument.
The colorspace conversion is maded by the glupload element.

- doublecube:
A local video source is displayed into two renderers.
The first one is a normal 2D screen, the second is a 3D cube.
We can visually check that the video is displayed at the same speed
in the two renderers.

- recordgraphic:
Show how to use the glfilterapp to define the draw callback in a gstreamer client code.
The scene is recorded into an avi file using mpeg4 encoder.
The colorspace conversion is made by the gldownload element.
