Added few more stubs so that control reaches to DestroyDevice().

29 * \section GLAPIIntroduction Introduction
30 *
31 * The Mesa GL API module is responsible for dispatching all the
32 * gl*() functions. All GL functions are dispatched by jumping through
33 * the current dispatch table (basically a struct full of function
34 * pointers.)
35 *
36 * A per-thread current dispatch table and per-thread current context
37 * pointer are managed by this module too.
38 *
39 * This module is intended to be non-Mesa-specific so it can be used
40 * with the X/DRI libGL also.
