illumos gate

Sync upstream activity in FreeBSD's bhyve into illumos.

The following list shows the commits considered as part of this sync.
The characters in the first columns indicate the action taken.

There are no major new features in this set, but in addition the usual improvements to the nvme driver, it also includes some work towards allowing generated ACPI tables to be loaded in the future, and I've been able to stop suppressing a lot of the compiler and smatch warnings due to upstream cleanups.
