DRI2: add SwapBuffers support
Support the new DRI2 protocol request, DRI2SwapBuffers, in both direct and indirect rendering context. This request allows the display server to optimize back->front swaps (e.g. through page flipping) and allows us to more easily support other GLX features like swap interval and the OML sync extension in DRI2.
