Fix Bug 692: Add tracking of VERTEX_ARRAY_BINDING, and enable allowing a bound non default VAO to pass VBO enabled test, even if VBO is disabled.

VAO is available if: GL >= 3.0 or is having GL_ARB_vertex_array_object extension.

checkBufferObject(..) checks whether VERTEX_ARRAY_BINDING has a non default VAO bound in case
no VBO is being bound and VAO is allowed.

glBindVertexArray(int) is being tracked, i.e. on state VERTEX_ARRAY_BINDING
