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.
