[reSIProcate] DUM features

["Daniel Shi" <daniel@xxxxxxxx>]

Hi,

 

Feature implementation has been added to class DialogUsageManager. A DUM feature allows you to add custom behavior to the messages DUM receives and sends. Features are shared pointers because they may be both incoming and outgoing features. Please see DumFeature and DumFeatureChain classes.

 

Major changes:

 

1). ServerAuthManger is now a feature. Method setServerAuthManager adds the ServerAuthManager feature to the beginning of the incoming feature chain. setServerAuthManager takes a resip::SharedPtr of ServerAuthManger instead of an std::auto_ptr.

2). An additional parameter is added to the constructor of the DialogUsageManager. DialogUsageManager decides whether or not to create default features based on the value of this argument. The default value is false. There are currently two default features: IdentityHandler and EncryptionManager.

3). Two new methods addIncomingFeature and addOutgoingFeature can be used to add features.

 

Changes have been committed to the main (5144).

 

Thanks,

Daniel
