* harbour/include/hbclass.ch
  * harbour/include/hbvm.h
  * harbour/source/rtl/tclass.prg
  * harbour/source/vm/classes.c
  * harbour/source/vm/hvm.c
    ! fixed bug in real codeblock scoping which was exploited by
      dictionary resizing
    * changed ACCESS messages to ASSIGN ones when object item
      reference is created for proper READONLY scope checking.
      The reference to object variable can be created only when
      caller has sufficient ASSIGN privileges.
    + added FRIEND CLASS and FRIEND FUNCTION support.
      It's enough to add class definition:
         FRIEND CLASS <classFunc1> [, <classFuncN> ]
      and/or:
         FRIEND FUNCTION <FuncName1> [, <FuncNameN> ]
      and all methods of given class or given function will be able
      to access private variables.
      Warning!!! Friends cannot access overloaded non virtual methods.
                 This feature is available _ONLY_ for real class members.
    + added MODULE FRIENDLY to class definition. It causes that all other
      functions and classes defined in the same .prg module will have
      friend privileges. In such way works xHarbour and there is now way
      to disable this "feature" what is IMHO bug. In Harbour programmer
      has to explicitly enable it (until he will not change / add new
      preprocessor rule and set it as default ;-)). Syntax:
         CREATE CLASS .... MODULE FRIENDLY
            ...
         END CLASS

  * harbour/source/vm/proc.c
  * harbour/source/vm/runner.c
    * updated function symbols processing

  * harbour/source/compiler/harbour.c
    * added note in hb_compOptimizeFrames() about exceeding maximum number
      of local variables (255). We should add new pcode(s) HB_P_LARGE[V]FRAME
      or generate compile time error.

  * harbour/source/vm/macro.c
    % minor optimizations
