Update stats in struct ipstat using four new macros, IPSTAT_ADD(),

IPSTAT_INC(), IPSTAT_SUB(), and IPSTAT_DEC(), rather than directly
manipulating the fields across the kernel.  This will make it easier
to change the implementation of these statistics, such as using
per-CPU versions of the data structures.
