21013dcf1b
This change introduces "base classes" of the AIDL interfaces that are implemented in vendor provided ImsServices. This allows for new APIs to be added to the AIDL files, along with stub implementation of those AIDLs in the base classes. By extending from the base class, older implementations of the AIDL interfaces will not need to be updated when the interface changes. This change also moves some of the com.android.ims classes from frameworks/opt/net/ims to frameworks/base. Any class that will be used in the new unbundled ImsService system will need to be in the framework, as opposed to the optional library that they are in now.
