Fix QtCreator debugging on Android 5.0 devices

Browse Source 
Add a socket based handshake method for gdb. The previous file based
method remains for now and can be activated from Qt creator. It will
be used by older creator builds but has the limitation of not working
on 5.0 devices.

The new mechanism works on pre 5.0 devices too.
