Fabiano Rosas	86a0ceb1ce	migration: Rename instances of start To make it easier to follow the code, rename the functions that start the migration thread and migration coroutine to contain the word "start". This will give new contributors the chance of seeing the word start and reaching the actual migration code, instead of twists and turns of qio_channel_add_watch and qio_task_run_in_thread. Remove all other instances of "start" and use wording more suitable to what the current migration stage is. The transport code such as fd_start_migration_outgoing becomes fd_connect_outgoing, the early setup code such as qemu_start_incoming_migration becomes qemu_setup_incoming_migration and so on.

Peter Xu	c9a7e83c9d	migration/multifd: Drop unnecessary helper to destroy IOC Both socket_send_channel_destroy() and multifd_send_channel_destroy() are unnecessary wrappers to destroy an IOC, as the only thing to do is to release the final IOC reference. We have plenty of code that destroys an IOC using direct unref() already; keep that style.

Peter Xu	72b90b9687	migration/multifd: Cleanup outgoing_args in state destroy outgoing_args is a global cache of socket address to be reused in multifd. Freeing the cache in per-channel destructor is more or less a hack. Move it to multifd_send_cleanup_state() so it only get checked once. Use a small helper to do so because it's internal of socket.c.

Het Gala	34dfc5e407	migration: convert socket backend to accept MigrateAddress Socket transport backend for 'migrate'/'migrate-incoming' QAPIs accept new wire protocol of MigrateAddress struct. It is achived by parsing 'uri' string and storing migration parameters required for socket connection into well defined SocketAddress struct.

Peter Xu	36f62f11e4	migration: Postcopy preemption preparation on channel creation Create a new socket for postcopy to be prepared to send postcopy requested pages via this specific channel, so as to not get blocked by precopy pages. A new thread is also created on dest qemu to receive data from this new channel based on the ram_load_postcopy() routine. The ram_load_postcopy(POSTCOPY) branch and the thread has not started to function, and that'll be done in follow up patches. Cleanup the new sockets on both src/dst QEMUs, meanwhile look after the new thread too to make sure it'll be recycled properly. Reviewed-by: Daniel P.

Longpeng(Mike)	d658f65c16	migration: unify the framework of socket-type channel Currently, the only difference of tcp channel and unix channel in migration/socket.c is the way to build SocketAddress, but socket_parse() can handle these two types, so use it to instead of tcp_build_address() and unix_build_address(). The socket-type channel can be further unified based on the up, this would be helpful for us to add other socket-type channels.
