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.
