Per-domain I/O is now something drivers must manually request, and must
keep track of within their own state rather than in the ScrnInfoRec.
It's not really possible to split that into two steps without an
additional intermediate ABI break, so don't even try. Drivers that want
source compatibility should ifdef on the presence of xf86UnmapLegacyIO.
As a fringe benefit, domain-aware I/O is now OS-independent, relying
only on support in pciaccess. Simplify OS PCI setup to reflect this.
The IOADDRESS type is kept around to help drivers through the API
transition and will be removed at some point in the future.
