None of XAA, EXA, or UXA do any hardware access during CreateGC, so they
don't need VGA arbitration. I haven't found any open source drivers that
hook CreateGC, so they're safe. I'd be surprised if any driver directly
hooks CreateGC and does hardware access from it and needs VGA
arbitration.

Right now, when there is more than one vide card on the machine, we're
adopting a pessimistic approach and setting all cards to decode VGA legacy
address.
Some cards may want to skip the arbitration and the only way to do so is
through pci_device_vgaarb_decodes. Therefore, send the desired kind of
resource instead force the worst case.
Note that xf86VGAarbiterDeviceDecodes is not being used so far by any
open-source driver. Even so, API break.

Because some EnterVT code needs to remove it self from the
call chain, we need to fix all of the wrappers to correctly
unwrap/rewrap during the call chain. This is a follow-on to the fix
for bug 27114 in commit 68a9ee8370.

This patch only changes the API, not the implementation of the
devPrivates infrastructure. This will permit a new devPrivates
implementation to be layed into the server without requiring
simultaneous changes in every devPrivates user.

The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.
X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.

This is RAC's remnant. Any sane person would use a more wise method of

This adds support for using the libpciaccess interface for
vga arbitration support on top of a kernel which supports it.
Currently patches are queued for kernel 2.6.32 in jbarnes
pci tree, and shipping in Fedora kernel.
