  migration: remove qemu_get_fd method from QEMUFile (2016-05-26 11:32:21 +0530)

----------------------------------------------------------------
migration: add TLS support to the migration data channel

This is a big refactoring of the migration backend code - moving away from
QEMUFile to the new QIOChannel framework introduced here.  This brings a
good level of abstraction and reduction of many lines of code.

This series also adds the ability for many backends (all except RDMA) to
use TLS for encrypting the migration data between the endpoints.

----------------------------------------------------------------
