[Playerstage-developers] Position device "lock" flag

I have been having some problems with multiple clients sending 
"conflicting" motor commands to the position device. So I added a 
"locked" flag to the position device: it's "informational" only, just a 
hint that clients can set and unset; it doesn't actually affect access 
to the device, but I can have my clients do something like:

while(position.Locked())
	player.Read();
position.SetSpeed(t, r);

and that is an ok solution for now.

Let me know if I should commit the change, or just post it to the patch 
tracker for people who might want it to use.

Maybe an even better solution would be to add such a feature to all 
devices, and have player queue up messages while it's locked?
