Considerably rework the ifmcstat utility.
* Build with or without INET, INET6, or KVM features.
* When built without KVM, the sysctl-based getifmaddrs() function
is used as the back-end for the utility.
* Reflect the fact that FreeBSD now uses the in_multi refcount as
a true refcount.
* Style.
The utility may now be run without super-user privilege, albeit with
a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.
