Spent the day working on more DRI interface cleanups. This one ties the DRM firmly to a specific device. It should break systems with old X Servers and multiple heads that are DRI-capable in that some heads won't init the DRI, but nothing else. This sort of configuration has been relatively broken anyway, so it's not too big a deal. It removes some ugliness from the DRM, and will make future changes like the lower-level graphics layer more doable. Also, the DRM no longer offers a service of getting the irq of any pci device (now it's restricted to just the device the DRM is attached to), and the ioctl to install the irq handler no longer cares about the irq number that was set if the interface version is set high enough (1.2).

The nice part is this change doesn't even mean any modifications to the X Server, though it'll remove some code from the kdrive DRI implementation I'm working on since I'm going to insist on up to date DRM for that.
