[git pull] unreviewed multi-gpu + randr 1.4 fixes

[Dave Airlie]

Hi Keith,

all on the list, one even has a r-b tag on it, the rest are mostly crickets.

These are pretty much all in the Fedora 18 X server, mostly as-is.

These fixes enable reverse prime support, so we can use the
nouveau/ati outputs from the intel rendering, the drivers have other
bits to make it work,

The randr changes are to allow things like gnome dialog box to notice
if a USB device
gets disconnected, and remove it from the dialog.

There is also one real fix (the cleanup provider properly) that is
probably the most
important thing in here.

The following changes since commit 8b328d4ee3873bc0a7a34f2cb9d301827244b98c:

  dix: Make small bitfields that store enums unsigned (2013-01-08
