The BUS_RESCAN() method rescans a single bus device checking for devices
that have been added or removed from the bus. A new 'rescan' command is
added to devctl(8) to trigger a rescan.

The POSIX version of basename() doesn't use a 'const char *' argument;
the function may overwrite its input buffer. Instead of copying the
input string, let's just simplify this code by using our getprogname()
function that already returns the name of the application in the right
format.

sysvmsg, sysvsem, and sysvshm, with the following bahavior:
inherit: allow full access to the IPC primitives. This is the same as
the current setup with allow.sysvipc is on. Jails and the base system
can see (and moduly) each other's objects, which is generally considered
a bad thing (though may be useful in some circumstances).
disable: all no access, same as the current setup with allow.sysvipc off.
new: A jail may see use the IPC objects that it has created. It also
gets its own IPC key namespace, so different jails may have their own
objects using the same key value. The parent jail (or base system) can
see the jail's IPC objects, but not its keys.

Previously, many errors (such as the PCI device not being attached
to the ppt(4) driver) resulted in bhyve silently exiting without
starting the virtual machine. Now any errors encountered when
configuring a virtual slot for a PCI passthru device should be noted
on stderr.
