[libvirt] [PATCH 4/8] qemu: Make migration params usable outside migration
So far migration parameters were changed only at the beginning of
migration mostly via an automatic translation from flags and typed
parameters. We need to export a few more functions to support APIs which
may set migration parameters while migration is already running.
