These modifications improve the monitoring support of the container. Now
several readers can attend the events from one or several containers.
The syntax of the command has been enhanced to interpret regular expressions.
If you want to monitor foo, lxc-monitor -n foo is the right command. If you
want to monitor foo and bar, you should specify lxc-monitor -n "foo|bar",
if you want to monitor all containers with the name beginning with 'foo',
you have to specify lxc-monitor -n "foo.*". More complex regexp can be specified
in accordance with the POSIX definitions, man regex (7).
