Simplify the meaning of return values from the inout handlers. After this change 0 means success and non-zero means failure.
This also helps to eliminate VMEXIT_POWEROFF and VMEXIT_RESET as return values from VM-exit handlers.

Add emulation of the "outsb" instruction. NetBSD guests use this to write to the UART FIFO.
The emulation is constrained in a number of ways: 64-bit only, doesn't check for all exception conditions, limited to i/o ports emulated in userspace.
Some of these constraints will be relaxed in followup commits.

Support soft power-off via the ACPI S5 state for bhyve guests. - Implement the PM1_EVT and PM1_CTL registers required by ACPI. The PM1_EVT register is mostly a dummy as bhyve doesn't support any of the hardware-initiated events. The only bit of PM1_CNT that is implemented are the sleep request bits (SPL_EN and SLP_TYP) which request a graceful power off for S5. In particular, for S5, bhyve exits with a non-zero value which terminates the loop in vmrun.sh. - Emulate the Reset Control register at I/O port 0xcf9 and advertise it as the reset register via ACPI. - Advertise an _S5 package. - Extend the in/out interface to allow an in/out handler to request that the hypervisor trigger a reset or power-off. - While here, note that all vCPUs in a guest support C1 ("hlt").

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.

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.
