Restore the CAM XPT peripheral generation counter, and export it via sysctl.
Define it as an atomic uint32_t. These increments happen infrequently
enough for the atomic overhead to be a problem, and since they're now
independent atomics, they won't contend with xpt_lock_buses().
This counter is useful as a means of cheaply identifying whether any changes

that the counter won't change on them while being returned or while processing

When mountd is creating sockets, it iterates over all addresses specified
in the "hosts" array and eventually looks up the network address with
getaddrinfo(). At one point it checks for a numeric address and if it
sees one, it sets a hint parameter to force getaddrinfo to interpret the
host as a numeric address. However that hint is not cleared for subsequent
iterations of the loop and if any hosts seen after this point are host names,
getaddrinfo will fail on the name. The result of this bug is that you cannot
pass a host name to the -h flag.
Unfortunately, the first iteration will either process ::1 or 127.0.0.1,
so the flag is set on the first iteration and all host names will fail
to be processed.
The same bug applies to rpc.lockd and rpc.statd, so fix them too.

Simplify instruction restart logic in bhyve.

explicitly via 'vm_restart_instruction()'. The APIs behave identically in

emulation code that executes in both contexts.
bhyve(8) VM exit handlers now treat 'vmexit->rip' and 'vmexit->inst_length'
