Log Message:
Added per-addr input/output statistics.  Currently just support netatalk
and netinet, currently only tested under netinet.

Disabled by default, enabled by compiling the kernel with option
IFA_STATS.  Enabling this feature seems to make the ip_output function
take 13% longer than before, which should be OK for people that need
this feature.
