[PATCH 2/3] Restore extern to the declaration of __glXDRISWRastProvider

[Jon TURNEY]

b86aa74 dropped the 'extern' from the declaration of __glXDRISWRastProvider

This turns out to be important to me, as without it, the final link only gets
the tentative definition of __glXDRISWRastProvider implied by the declaration,
and not the proper one from glxdriswrast.c, presumably because nothing else
references anything in the object that file generates.
