Create the skeletal binder interface for wpa_supplicant. The interface hierarchy is based off the existing dbus interface(https://w1.fi/wpa_supplicant/devel/dbus.html). Since we use libbinder, the binder interface codebase needs to be written in C++ and can only be compiled on Android platform for now. The aidl files define binder RPC interfaces. The Android build system generates the corresponding C++ interface classes which needs to be implemented by the server process. The clients can obtain a reference to the binder service (root object) using: android::String16 service_name("fi.w1.wpa_supplicant"); android::sp<android::IBinder> binder = android::defaultServiceManager()->getService(service_name); Once a reference to the root object is retrieved, the clients can obtain references to other RPC objects using that root object methods.
