  Log:
  - Fix rman_manage_region() to be a lot more intelligent.  It now checks
    for overlaps, but more importantly, it collapses adjacent free regions.
    This is needed to cope with BIOSen that split up ports for system devices
    (like IPMI controllers) across multiple system resource entries.
  - Now that rman_manage_region() is not so dumb, remove extra logic in the
    x86 nexus drivers to populate the IRQ rman that manually coalesced the
    regions.
