quick heads-up, this change in base needs nsh to catch up. I didn't
check but I assume the existing code is going to be similar enough to
what's in usr.bin/netstat/mbuf.c that it should be easy to adapt.

Log message:
Protect mbuf statistics counter with splnet.

MP safe conters with per CPU memory still need spl protection when
called from interrupt context.  Some increments of mbuf counters
had that, others did not.  Introduce inline function mbstat_inc()
and enum counter types for mbufs, like we have elsewhere.  With
that mbufs counter increment takes splnet() everywhere.

OK mvs@ dlg@
