d6fe268fdd Fix discrepancy between the IOAPIC ID advertised by firmware tables and the
actual value read by the guest from the device. The IOAPIC ID is now set to
zero in both MPtable/ACPI tables as well as in the ioapic device emulation.

a1a4cbea58 Make the virtual ioapic available unconditionally in a bhyve virtual machine.
This is in preparation for moving the ioapic device model from userspace to
vmm.ko.

062b878f58 Changes required for OpenBSD/amd64:
- Allow a hostbridge to be created with AMD as a vendor.
  This passes the OpenBSD check to allow the use of MSI
  on a PCI bus.
- Enable the i/o interrupt section of the mptable, and
  populate it with unity ISA mappings. This allows the
  'legacy' IRQ mappings of the PCI serial port to be
  set up. Delete unused print routine that was obscuring code.
- Use the '-W' option to enable virtio single-vector MSI
  rather than an environment variable. Update the virtio
  net/block drivers to query this flag when setting up
  interrupts.: bhyverun.c
- Fix the arithmetic used to derive the century byte in
  RTC CMOS, as well as encoding it in BCD.

f82d0672c7 config checksum is over the entire fixed portion, not just the
config header. FreeBSD doesn't check this but other o/s's do.

b060ba5024 Simplify the assignment of memory to virtual machines by requiring a single
command line option "-m <memsize in MB>" to specify the memory size.

Prior to this change the user needed to explicitly specify the amount of
memory allocated below 4G (-m <lowmem>) and the amount above 4G (-M <highmem>).

The "-M" option is no longer supported by 'bhyveload' and 'bhyve'.

The start of the PCI hole is fixed at 3GB and cannot be directly changed
using command line options. However it is still possible to change this in
special circumstances via the 'vm_set_lowmem_limit()' API provided by
libvmmapi.

91039bb268 Specify the length of the mapping requested from 'paddr_guest2host()'.
This seems prudent to do in its own right but it also opens up the possibility
of not having to mmap the entire guest address space in the 'bhyve' process
context.

e285ef8d28 Rename fbsdrun.* -> bhyverun.*
bhyve is intended to be a generic hypervisor, and not FreeBSD-specific.

(renaming internal routines will come later)

fbfc1c763c Remove mptable generation code from libvmmapi and move it to bhyve.
Firmware tables require too much knowledge of system configuration,
and it's difficult to pass that information in general terms to a library.
The upcoming ACPI work exposed this - it will also livein bhyve.

Also, remove code specific to NetApp from the mptable name, and remove
the -n option from bhyve.
