Pull in bhyve bug fixes and changes to allow UEFI booting. This provides Windows support.
Tested on Intel and AMD with: - Arch Linux i386+amd64 (kernel 4.3.3) - Ubuntu 15.10 server 64-bit - FreeBSD-CURRENT/amd64 20160127 snap - FreeBSD 10.2 i386+amd64 - OpenBSD 5.8 i386+amd64 - SmartOS latest - Windows 10 build 1511'
Huge thanks to Yamagi Burmeister who submitted the patch and did the majority of the testing.
r284539 - bootrom mem allocation support r284630 - Add SO_REUSEADDR when starting debug port r284688 - Fix a regression in "movs" emulation r284877 - verify_gla() non-zero segment base fix r285217 - Always assert DCD and DSR in the uart r285218 - devmem nodes moved to /dev/vmm.io/ r286837 - Add define for SATA Check-Power-Mode r286838 - Add simple (no-op) SATA cmd emulations r288470 - Increase virtio-blk indirect descs r288522 - Firmware guest query interface r288524 - Fix post-test typo r288826 - Clean up SATA unimplemented cmd msg r289001 - Add -l option to specify userboot path

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.
