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

b9e1cd3732 glshaderelement: implement on-demand create-shader signalling
One may not have an GstGLContext available or current in the thread where one
would need to update the shader.  Support this by signalling create-shader
whenever the one-shot 'update-shader' is set to TRUE.

f0a0fcb0bf gl/examples: add a live shader demo using the new GstGLSLStage
Implemented with videotestsrc ! glshader ! glupload ! gtkglsink

Errors on an invalid shader compilation are ignored however any error
provided by the glsl compiler is printed to stdout.
