if not given an interface to monitor by default, pick the one
with the most bytes in/out the first time and keep using it.

in addition to picking the most likely intersting interface,
this actually fixes a bug where interfaces coming/going in
the middle of eg, "netstat -b -w 1", may end up showing the
data for another interface on any output line (including the
the header declaring the interface!)

Update for per-cpu interface statistics.

iqdrops when kvm read failed.

Remove mkludge stuffs

For unknown reasons, IPv6 multicast addresses are linked to a first
IPv6 address assigned to an interface. Due to the design, when removing
a first address having multicast addresses, we need to save them to
somewhere and later restore them once a new IPv6 address is activated.
mkludge stuffs support the operations.

This change links multicast addresses to an interface directly and
throws the kludge away.

Note that as usual some obsolete member variables remain for kvm(3)
users. And also sysctl net.inet6.multicast_kludge remains to avoid
breaking old ifmcstat.

TODO: currently ifnet has a list of in6_multi but obviously the list
should be protocol independent. Provide a common structure (if_multi
or something) to handle in6_multi and in_multi together as well as
ifaddr does for in_ifaddr and in6_ifaddr.

Fix showing multicast addresses of !IFF_UP interfaces

netstat appends '*' to the name of an interface without IFF_UP, so
if_nametoindex which is used in mc_print fails. mc_print needs just
an interface index so pass it instead of a tweaked interface name.

Fix "sidewaysintpr", the thing that prints interface statistics in a
loop, to use signals properly. There are two copies of this code; one
uses kvm and the other uses sysctls. One copy had been updated to use
sigset_t and sigsuspend; the other was using vintage sigpause(). Sync
up the code so both use sigpause. Also, use sig_atomic_t, and block
SIGALRM when not waiting for it to avoid a small and unlikely but real
race.

Since the non-modernized copy of the code *had* for some been
modernized to use setitimer instead of just alarm(), propagate that
change to the other copy.

These copies could share more logic than they do.
