Add incStrong and decStrong methods to android_native_{window,buffer}_t. 

This change adds the methods necessary to use sp<> to handle refcounting
android_native_window_t and android_native_buffer_t.  The new methods forward
the refcounting operations to the corresponding android_native_base_t
functions.
