[PATCH] [RFC] Do the PIN check in SIMManager

[Denis Kenzior]

Hi Andrew,

Actually more like 7.  However, right now we only really care about pin lock.  
We can theoretically optimize the query somewhat by looking at whether the 
CPIN is being asked for at startup.  If it is, the PIN is locked, and unlocked 
otherwise.  Then the LockPin / UnlockPin callbacks can update the state 
appropriately.

So the thought right now is to add LockedPins property, which will be a list 
of pins that are currently locked.  If nothing is locked, an empty list is 
returned.

For now I'm planning to implement LockedPins support for pin only, but the 
others will have to be queried eventually as well.

Patches have been applied, thanks.
