mesa/tests: Sanity check the ES2 dispatch table
This test is only built when shared-glapi is used. Because of changes elsewhere in the tree that were necessary to make shared-glapi work correct with GLX, it's not feasible to make the test function both ways. The list of expected functions originally came from the functions set by api_exec_es2.c. This file no longer exists in Mesa (but api_exec_es1.c is still generated). It was the generated file that configured the dispatch table for ES2 contexts. This test verifies that all of the functions set by the old api_exec_es2.c (with the recent addition of VAO functions) are set in the dispatch table and everything else is a NOP. When adding ES2 (or ES3) extensions that add new functions, this test will need to be modified to expect dispatch functions for the new extension functions. v2: Expect VAO functions be non-NOP.
