Liav A 83ebd1882f Utilities: Add the memstat utility 
This small utility is something we probably needed for a very long
time - a way to print memory statistics in an elegant manner.

This utility opens /sys/kernel/memstat, reads it and decode the values
into human readable entries, possibly even into human-readable sizes.
