[PATCH 0/3] migration/postcopy: replace have_listen_thread check with PostcopyState check

[Wei Yang]

have_listen_thread is used to be a indication of whether postcopy thread is
running. Since we use PostcopyState to record state and the postcopy thread
only runs when postcopy_is_running(), we can leverage the PostcopyState to
replace the meaning of have_listen_thread.

To do so, two preparation cleanup is included.

Wei Yang (3):
  migration/postcopy: mis->have_listen_thread check will never be
    touched
  migration/postcopy: postpone setting PostcopyState to END
  migration/postcopy: replace have_listen_thread check with
    PostcopyState check
