Stateless SIP requests with TLS transport fail with EINVAL

User https://github.com/ndilieto opened this re issue against my libbaresip-android project: https://github.com/juha-h/libbaresip-android/issues/43. He also provided PR to fix it: https://github.com/juha-h/libbaresip-android/pull/42.  What is the best way to get the fix to re project?
