Commit: Po Lu <luangruo@yahoo.com>

    Flush frames after mouse face is cleared on a child frame in Haiku
    
    * src/haiku_support.cc (~EmacsWindow):
    (UpwardsSubsetChildren):
    (UpwardsUnSubsetChildren): Fix locking semantics.
    
    * src/haikuterm.c (haiku_read_socket): Flush dirty back buffers
    after clearing mouse face because the pointer was moved out of a
    frame.
