xserver and libpciaccess both need to open /dev/xf86, which can only
be opened once. I implemented pci_system_init_dev_mem() like Ian
suggested. This requires some minor changes to the BSD-specific
os-support code. Since pci_system_init_dev_mem() is a no-op on
FreeBSD this should be no problem.

New interfaces to map memory with MTRR (or similar) support.

Added new functions pci_device_map_range and pci_device_unmap_range to
handle mapping of PCI device BARs. These new interfaces allow the
possiblity of MTRRs on platforms that support them.

These additional APIs necessitated changing some internal interfaces. The
code for FreeBSD and Solaris has been updated but has not been compiled or
tested.

Old interfaces are marked deprecated and will eventually be removed.

hinkey (unmaps the whole BAR). Works so far for initial conversion of
