Merge bpfstat's functionality into the netstat(1) utility. This adds

a -B option which causes bpf peers to be printed. This option can be
used in conjunction with -I if information about specific interfaces
is desired. This is similar to what NetBSD added to their version of
netstat.

$ netstat -B
  Pid  Netif  Flags      Recv      Drop     Match Sblen Hblen Command
 1137    lo0 p--s--         0         0         0     0     0 tcpdump
  205   sis0 -ifs-l     37331         0         1     0     0 dhclient

$ netstat -I lo0 -B
  Pid  Netif  Flags      Recv      Drop     Match Sblen Hblen Command
 1174    lo0 p--s--         0         0         0     0     0 tcpdump

-Add bpf.c which stores all the code for retrieving and parsing bpf
 related statistics.
-Modify main.c to add support for the -B option and hook it into the
 program logic.
-Add bpf.c to the build.
-Document this new functionality in the man page and bump the revision
 date.
-Add prototype for bpf_stats function.
