Changes to allow the GENERIC+bhye kernel built from this branch to
run as a 1/2 CPU guest on an 8.1 bhyve host.

bhyve/inout.c
      inout.h
      fbsdrun.c
 - Rather than exiting on accesses to unhandled i/o ports, emulate
   hardware by returning -1 on reads and ignoring writes to unhandled
   ports. Support the previous mode by allowing a 'strict' parameter
   to be set from the command line.
   The 8.1 guest kernel was vastly cut down from GENERIC and had no
   ISA devices. Booting GENERIC exposes a massive amount of random
   touching of i/o ports (hello syscons/vga/atkbdc).

bhyve/consport.c
dev/bvm/bvm_console.c
 - implement a simplistic signature for the bvm console by returning
   'bv' for an inw on the port. Also, set the priority of the console
   to CN_REMOTE if the signature was returned. This works better in
   an environment where multiple consoles are in the kernel (hello syscons)

bhyve/rtc.c
 - return 0 for the access to RTC_EQUIPMENT (yes, you syscons)

amd64/vmm/x86.c
          x86.h
 - hide a bunch more CPUID leaf 1 bits from the guest to prevent
   cpufreq drivers from probing.
   The next step will be to move CPUID handling completely into
   user-space. This will allow the full spectrum of changes from
   presenting a lowest-common-denominator CPU type/feature set, to
   exposing (almost) everything that the host can support.
