Prevent integer overflow in kernel and userland when checking mbuf
limits.  Convert kernel variables and calculations for mbuf memory
into long to allow larger values on 64 bit machines.  Put a range
check into the kernel sysctl.  For the interface itself int is still
sufficient.  In netstat -m cast all multiplications to unsigned
long to hold the product of two unsigned int.
