qemuMigrationPrepareDirect is not a callback, and not a public API, so
you are free to change its signature and add a flags parameter if that
is necessary to get the information to the right places. The only
signatures you can't change are in src/libvirt.c and in functions
serving as callbacks registered through signatures in src/driver.h.
