android: Async setupConnection binder call
Make setupConnection oneway/async. Add a ICallbackInt interface to
return the PID of the child process. The reply is then posted back to
launcher thread. Connection setup is already mostly async so only
involves moving related code to the reply callback.
One caveat is that getCallingPid no longer works and just returns 0
for oneway calls. The pid check is not strictly necessary, so dropped
the from setupConnection instead.
