* clutter/cogl/gl/cogl.c (error_string):

Browse source 
* clutter/cogl/gles/cogl.c (error_string): Rename to
	_cogl_error_string and remove the static scoping so that it can be
	called in cogl-texture etc.

	* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_new_from_foreign):
	GE(*) can't be used to wrap around calls that use the return
	value.

	* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw, cogl_texture_polygon): Remove GE(*)
	wrapper around calls in the middle of a glBegin/glEnd pair which
	otherwise always generate an error because glGetError can only be
	called outside of the pair.

	* clutter/cogl/gl/cogl-internal.h: Include stdio.h when definig
	COGL_DEBUG and declare a prototype for _cogl_error_string.

	* clutter/cogl/gles/cogl-internal.h: Match GE(*) macro to GL
	version.
