semi-seamless migration details:
migration source side
---------------------
(1) spice_server_migrate_connect (*): tell client to link
to the target side - send SPICE_MSG_MAIN_MIGRATE_BEGIN.
This should be called upon client_migrate_info cmd.
client_migrate_info is asynchronous.
(2) Complete spice_server_migrate_connect only when the client has been connected
to the target - wait for SPICE_MSGC_MAIN_MIGRATE_(CONNECTED|CONNECT_ERROR) or a timeout.
(3) spice_server_migrate_end: tell client migration it can switch to the target - send
SPICE_MSG_MAIN_MIGRATE_END.
(4) client cleans up all data related to the connection to the source and switches to the target.
It sends SPICE_MSGC_MAIN_MIGRATE_END.
migration target side
---------------------
(1) the server identifies itself as a migraiton target since the client is linked with (connection_id != 0)
(2) server doesn't start the channels' logic (channel->link) till it receives SPICE_MSGC_MAIN_MIGRATE_END
from the client.
* After migration starts, the target qemu is blocked and cannot accept new spice client
connections. Thus, we trigger the connection to the target upon client_migrate_info
command.
