Watches child_pid. When the process exists, the "child-exited"
signal will be called. Use vte_terminal_get_child_exit_status() to
retrieve the child's exit status.
Prior to calling this function, a VtePty must have been set in terminal
using vte_terminal_set_pty_object().
When the child exits, the terminal's VtePty will be set to NULL.
Note: g_child_watch_add() or g_child_watch_add_full() must not have
been called for child_pid, nor a GSource for it been created with
g_child_watch_source_new().
Note: when using the g_spawn_async() family of functions,
the G_SPAWN_DO_NOT_REAP_CHILD flag MUST have been passed.
