  + harbour/source/vm/hashes.c
  + harbour/source/vm/hashfunc.c
    + added hash items, f.e.:
         local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
         ? h2[ "a" ], h2[ "b ]
    + added support for DYNAMIC function declaration - it allow to define
      functions which are lately bound at runtime, f.e.:
         /*** t01.prg ***/
         dynamic func1
         proc main()
         local h:=__hrbload("t02.hrb")
         ? func1()
         return

         /*** t02.prg ***/
         func func1
         return "Hello!!!"

    % use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
      it reduce memory usage, FUNCALL is much smaller then FUNCTION
    % use symbol scope bits when possible instead of making some linear scan
    + added new enumarator message: __ENUMKEY - it allow to access
      key value when hash item is base enumerator value, f.e.:
         proc main()
         local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
         heval( h, { |k,v,i| qout( k, v, i ) } ); ?
         for each v in h
            ? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
                       valtype(v:__enumBase())
            v += 0.123
         next
         ? ;heval( h, { |k,v,i| qout( k, v, i ) } )
         return
    + added C level hb_hash*() functions
    + added support for full HASH item cloning and updated array cloning
      to also clone nested hashes - please note that xHarbour does not do
      that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
      _DOES_NOT_ clone _ANY_ nested items.

  * harbour/include/hbextern.ch
    + added hash functions HB_H*()
    * changed INET*() functions to HB_INET*()
    + added hash functions H*() and socket functions INET*() when
      HB_COMPAT_XHB is set

  * harbour/include/hbtypes.h
    + added missing HB_EXTERN_BEGIN / HB_EXTERN_END

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    ! added protection against automatic word concatenation in some cases
    ! fixed preprocessing expressions when match marker matches ';' token

  * harbour/source/rtl/Makefile
  + harbour/source/rtl/itemseri.c
    + added functions for item serialization: HB_SERIALIZE() and
      HB_DESERIALIZE() - these function are not binary compatible
      with xHarbour functions with the same names but make very
      similar job with the exception to serialization of codeblock
      and object variables - Harbour does not allow to serialize
      codeblocks and serialize objects as arrays.
      In most cases these functions can replace the xHarbour ones
    + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
      by HB_COMPAT_XHB macro - this functions are only for compatibility
      with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
      dummy function which returns first parameter and HB_DESERIALNEXT()
      is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
      use them.

  * harbour/source/rtl/hbinet.c
    * changed INET*() functions to HB_INET*() and enable them for default
      build
    + added INET*() functions wrappers covered by HB_COMPAT_XHB macro

  * harbour/source/rtl/hbrandom.c
    + added HB_RANDOMINT() - xHarbour compatible

  * harbour/source/rtl/len.c
    + added support for HASHes

  * harbour/source/rtl/valtype.c
    + added support for HASHes
    + added set of HB_IS*() functions - they are a little bit faster then
      calling VALTYPE( v ) == <cVal>
    - removed HB_ISBYREF() - this function cannot longer work, it was using
      a Clipper incompatible anomalies in passing variables by reference I
      fixed so it has to stop to work. If it will be realy necessary to
      implement HB_ISBYREF() function then please inform me - it will have
      to be done at compiler level or with some much deeper HVM stack
      checking.

  * harbour/source/vm/extend.c
    ! fixed hb_extIsArray() and hb_extIsObject() to work well with
      parameters passed by reference.
      Please note that now hb_extIsArray() return TRUE only for pure arrays
      not object values.

  * harbour/contrib/Makefile
  + harbour/contrib/tip/Changelog
  + harbour/contrib/tip/Makefile
  + harbour/contrib/tip/atokens.c
  + harbour/contrib/tip/base64x.c
  + harbour/contrib/tip/cgi.prg
  + harbour/contrib/tip/client.prg
  + harbour/contrib/tip/credent.prg
  + harbour/contrib/tip/cstr.prg
  + harbour/contrib/tip/encb64.prg
  + harbour/contrib/tip/encmthd.c
  + harbour/contrib/tip/encoder.prg
  + harbour/contrib/tip/encqp.prg
  + harbour/contrib/tip/encurl.prg
  + harbour/contrib/tip/ftpcln.prg
  + harbour/contrib/tip/hbhex2n.c
  + harbour/contrib/tip/httpcln.prg
  + harbour/contrib/tip/mail.prg
  + harbour/contrib/tip/popcln.prg
  + harbour/contrib/tip/smtpcln.prg
  + harbour/contrib/tip/tip.ch
  + harbour/contrib/tip/url.prg
  + harbour/contrib/tip/utils.c
    + added TIP library - code borrowed from xHarbour



   Please test - a lot of above code is not well tested, also some peaces
   were written over year ago for different things (f.e. serialization for
   NETRDD) and now I collected them and committed.
   The TIP library was not tested at all. It can be compiled but I cannot
   say if it works - I hope that people familiar with it can make necessary
   test and fixes.
   It's also not the final version of low level HASH item code. I'm working
   on more efficient structure which uses binary tries but I cannot say when
   I'll finish it (maybe in this weekend or maybe in next year) so I committed
   working version now even if I'm not happy with overall performance (BTW
   not worser then in xHarbour)
