Paulo Cesar Pereira de Andrade 31285d063e Make visible symbols required by xorg modules.
This patch exports all symbols required by the compilable
(in a x86 linux computer) xorg/driver/* modules.
  Still missing symbols worth mentioning are:

sunleo
	miFindMaxBand no longer available

intel	(uxa/uxa-accel.c)
	fbShmPutImage no longer available (and should have been static)

mga
	MGAGetClientPointer (should come from matrox's libhal)

  This is not a definitive "visibility" patch, as all it does is to
export missing symbols, but the modules that current don't compile,
may require more symbols once fixed, and third party drivers should
also require more symbols exported.
  A "definitive" patch should export symbols defined in the sdk.
