[reSIProcate] DialogUsageManager shutdown.

[palladin]

Dear resip devels.
resiprocate 1.9.2

Could you please advise with the next issue?
DilaogUsageManager allows to set ServerAuthManager instance. Then, 
during application shutdown I call 
DialogUSageManager::shutdown(DumShutdownHandler*).

I have caught an issue when there are half completed auth transations. I 
mean that dum fills mIncomingFeatureChainMap with raw pointers( 
DumFeatureChain* ).
After DUM is destroyed - mIncomingFeatureChainMap continues to reference 
to SharedPtr<DumFeature> list. In my case that was custom AuthManager, 
inherited from resip::ServerAuthManager. And I've got a crash.
Could you please consider next piece of code, which may help to resolve 
the issue?
