Currently creating a QEMUFile instance from a QIOChannel is quite simple only requiring a single call to qemu_fopen_channel_input or qemu_fopen_channel_output depending on the end of migration connection.
When QEMU gains TLS support, however, there will need to be a TLS negotiation done inbetween creation of the QIOChannel and creation of the final QEMUFile. Introduce some helper methods that will encapsulate this logic, isolating the migration protocol drivers from knowledge about TLS.
