* include/hbserial.ch
  * src/rtl/itemseri.c
    + added HB_SERIALIZE_IGNOREREF flag.
      This flag fully disables logic used to detect multireferences to the
      same complex (sub)items like arrays or hashes. It increses the speed
      of serialization but serialized data does not contain any information
      about refences, i.e. aVal[ 1 ] and aVal[ 2 ] in code below:
         aSub := { 1, 2, 3 }
         aVal := { aSub, aSub }
      are serialized as separated arrays. Additionally items with cyclic
      references like:
         aSub[ 2 ] := aSub
      cannot be serialized at all with HB_SERIALIZE_IGNOREREF flag because
      it will create infinite serialization loop and crash with out of
      memory message.

  * src/rtl/itemseri.c
    % rewritten algorithm used to detect cyclic and multi references in
      serialized items. The original algorithm has very high overhead when
      huge arrays were serialized, i.e. serialization of array with 1'000'000
      of subarrays needed about 30 minutes on my i5@3.30GHz. Now it needs
      less then a second and this time is only a little bit bigger then
      used by serialization with HB_SERIALIZE_IGNOREREF flag.
      This modification improve performance also in other code using Harbour
      serialization mechanism like I18N files, HBNETIO, GTNET, ... when large
      arrays or hashes are saved or transmitted.

  * include/hbapi.h
  * include/hbapicls.h
  * src/vm/arrays.c
  * src/vm/classes.c
  * src/vm/hashes.c
  * src/vm/itemapi.c
    * replaced algorithm used to detect cyclic and multi references in
      array and hash clone operations with new one similar to current
      item serial code. The speed improvement for very large arrays is
      the same as in case of serialization code.

  * src/rtl/gtsln/mousesln.c
    ! typo in while loop - synced with Viktor's branch
