Merge projects/bhyve to head.

'bhyve' was developed by grehan@ and myself at NetApp (thanks!).

Special thanks to Peter Snyder, Joe Caradonna and Michael Dexter for their
support and encouragement.

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.

Rework how guest MMIO regions are dealt with.

- New memory region interface. An RB tree holds the regions,
with a last-found per-vCPU cache to deal with the common case
of repeated guest accesses to MMIO registers in the same page.

- Support memory-mapped BARs in PCI emulation.

mem.c/h - memory region interface

instruction_emul.c/h - remove old region interface.
Use gpa from EPT exit to avoid a tablewalk to
determine operand address. Determine operand size
and use when calling through to region handler.

fbsdrun.c - call into region interface on paging
exit. Distinguish between instruction emul error
and region not found

pci_emul.c/h - implement new BAR callback api.
Split BAR alloc routine into routines that
require/don't require the BAR phys address.

ioapic.c
pci_passthru.c
pci_virtio_block.c
pci_virtio_net.c
pci_uart.c - update to new BAR callback i/f

Add 16550 uart emulation as a PCI device. This allows it to
be activated as part of the slot config options.
The syntax is:

-s <slotnum>,uart[,stdio]

The stdio parameter instructs the code to perform i/o using
stdin/stdout. It can only be used for one instance.
To allow legacy i/o ports/irqs to be used, a new variant of
the slot command, -S, is introduced. When used to specify a
slot, the device will use legacy resources if it supports
them; otherwise it will be treated the same as the '-s' option.
Specifying the -S option with the uart will first use the 0x3f8/irq 4
config, and the second -S will use 0x2F8/irq 3.

Interrupt delivery is awaiting the arrival of the i/o apic code,
but this works fine in uart(4)'s polled mode.

This code was written by Cynthia Lu @ MIT while an intern at NetApp,
with further work from neel@ and grehan@.
