MFC r257293.
Add support for PCI-to-ISA LPC bridge emulation. If the LPC bus is attached to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual machine was by presenting it as a PCI device that is mapped at the legacy I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach: - It did not work at all with UEFI because UEFI will reprogram the PCI device BARs and remap the COM1/COM2 ports at non-legacy addresses. - OpenBSD GENERIC kernel does not create a /dev/console because it expects the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device. - It was functional with a FreeBSD guest but caused the console to appear on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it is possible to have uart devices on the PCI bus in addition to the legacy COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is "-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is: "-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is: "-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.

Revamp the x86 instruction emulation in bhyve.
On a nested page table fault the hypervisor will: - fetch the instruction using the guest %rip and %cr3 - decode the instruction in 'struct vie' - emulate the instruction in host kernel context for local apic accesses - any other type of mmio access is punted up to user-space (e.g. ioapic)
The decoded instruction is passed as collateral to the user-space process that is handling the PAGING exit.
The emulation code is fleshed out to include more addressing modes (e.g. SIB) and more types of operands (e.g. imm8). The source code is unified into a single file (vmm_instruction_emul.c) that is compiled into vmm.ko as well as /usr/sbin/bhyve.

ACPI support for bhyve.
The -A option will create the minimal set of required ACPI tables in guest memory. Since ACPI mandates an IOAPIC, the -I option must also be used.
Template ASL files are created, and then passed to the iasl compiler to generate AML files. These are then loaded into guest physical mem.
In support of this, the ACPI PM timer is implemented, in 32-bit mode.
Tested on 7.4/8.*/9.*/10-CURRENT.

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 an explicit exit code 'SPINUP_AP' to tell the controlling process that an AP needs to be activated by spinning up an execution context for it.
The local apic emulation is now completely done in the hypervisor and it will detect writes to the ICR_LO register that try to bring up the AP. In response to such writes it will return to userspace with an exit code of SPINUP_AP.

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@.
