Implement server-side support for switch-host client migration. Client
side support is present already in the tree.
Setting the migration information is done using the existing
spice_server_migrate_info() function. A new
spice_server_migrate_switch() function has been added which triggers
sending out the switch-host message.
Seamless migration functions are left there for now.
spice_server_migrate_start() has been chamnged to just fail
unconditionally though as seamless migration is broken anyway.
