Add option to mlock qemu and guest memory 

In certain scenario, latency induced by paging is significant and 
memory locking is needed. Also, in the scenario with untrusted 
guests, latency improvement due to mlock is desired. 

This patch introduces a following new option to mlock guest and 
qemu memory: 

-realtime mlock=on|off

Can someone explain if/why we should use qemu option “-realtime mlock=off” ? 
I found no good documentation.
