Shutdown races...

[Wilfried Goesgens]

Kannel should wait for all smsc's to terminate before shutting down store.
else this will panic (especially with alexander malyshs store-dir)
on shutdown, if the store is terminated fist.
Please find a patch attached, that does a for loop over all available smsc's, 
test if they're still valid, if, wait for them to become shut down, 
and then continue to destruct kannel.
