Author: Daniel Stenberg <address@hidden>

    multi_done: prune DNS cache
    
    Prune the DNS cache immediately after the dns entry is unlocked in
    multi_done. Timed out entries will then get discarded in a more orderly
    fashion.
    
    Test506 is updated
    
    Reported-by: Oleg Pudeyev
    
    Fixes #2169
    Closes #2170
