Update stats in struct carpstats using two new macros: CARPSTATS_ADD()

Browse Source 
and CARPSTATS_INC(), rather than directly manipulating the fields of
the structure.  This will make it easier to change the implementation
of these statistics, such as using per-CPU versions of the data
structure.
