Binding on-demand #9: selectBackupTransport[Async]
Migrate selectBackupTransport()/selectBackupTransportAsync() to binding
on-demand. To mimic the bind-if-needed behavior that existed before for
selectBackupTransportAsync we now register-if-needed in the selection.
This means a new registerTransport() method was created in the
TransportManager. I intend to use this method with only few
modifications for the first-binding code.
