Modified files:
usr.bin/systat disks.c iostat.c main.c mbufs.c netstat.c
pigs.c swap.c vmstat.c
Log:
o Use snprintf rather than sprintf
o Add more checks for buffer overflows
o Use snprintf rather than strcat/cpy and have better checks for max
length exceeded.
Most of these changes are not exploitable buffer overruns, but it never
hurts to be safe.
