    PR threads/20743: Don't attempt to suspend or resume exited threads.

    When resuming a native FreeBSD process, ignore exited threads when
    suspending/resuming individual threads prior to continuing the process.

    gdb/ChangeLog:

        PR threads/20743
        * fbsd-nat.c (resume_one_thread_cb): Remove.
        (resume_all_threads_cb): Remove.
        (fbsd_resume): Use ALL_NON_EXITED_THREADS instead of
        iterate_over_threads.
