Add map_legacy interface

This allows platforms to hand back mmaps of the low 1M (ISA) address
space on a per-domain basis.

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.

Add stub version of pci_device_map_memory_range

This stub version of pci_device_map_memory_range allows the vesa driver and
other users of this interface to continue functioning with current
libpciaccess bits. That said, users of this interface should convert over
to pci_device_map_range as soon as possible.

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.

Gut old regex based search mechanism with a new mechanism that is modeled
after the Linux kernel. In addition to searching for devices by device
/ vendor ID, it is possible to search for devices by their domain / bus
/ slot / function.
Fix serious bus in the reading of ROMs and in the unmapping of regions. The
main point is that the map routine depens on the pci_mem_region::memory
pointer being non-NULL only when the region is mapped. Therefore, the
unmap routine should set it to NULL after unmapping.
Update to use new search API.
