This changes the module initalization order so that the GLX module initializes
after COMPOSITE. The reason for this change is to be able to initialize a
GLX visual config for the COMPOSITE ARGB visual.
Right now we default to "all" which gives us a situation much like before,
but when the "typical" option is implemented, we can change the default and
reduce the number of visuals the GLX module bloats the X server with.
Instead of the fragile setup where we filter the modes common between the
DDX generated GLX visuals and the DRI driver generated fbconfigs, we now
just take the fbconfigs returned by the DRI driver to be our supported set.
XFree86LOADER ifdefs, non-loadable hasn't been supported for a while
now. Remove completely gratuitious REMOVE_LOADER_CHECK_MODULE_INFO
ifdefs surrounding a call to a function added in XFree86 4.1 (!).
