RFC: xfree: dri2: libdrm as optional

Some drivers use DRI2 protocol but implement their own kernel rendering mananger. For these drivers, libdrm becomes useless. The only inconvenient right now to put libdrm optional to X server is concerning DRI2Authenticate. Such function uses drm_magic_t and drmAuthMagic symbols from libdrm. So I
