Summary: Locking for HAL configuration

Initial Comment:
Add the ability to lock a HAL configuration.  This would  
disable all "loadrt", "newsig", "link(sp|ps)", "addf" and  
other commands that can change the configuration.   
Two levels of locking should be implemented.  One  
should still permit "setp" and possibley "sets" (this  
allows tuning and such) the other should lock everything 
down tight. 
 
The locking should be implemented in the HAL library 
itself, not in halcmd.  Halcmd should have commands 
to turn locking on and off (and perhaps those commands 
should only be available to root - at least the unlock ones.)
