* harbour/source/vm/itemapi.c
    * minor modification in function order to group together the ones
      which can operate on reference counters
    + added additional stop condition in hb_itemUnRef() - we will have
      to make some modifications for the code which execute hb_itemUnRef()
      to resolve some possible conflicts with operators overloading and
      compiler optimizations

  * harbour/source/vm/classes.c
    * do not inherit friends - seems that our classes code was too
      friendly ;-)
      It also effectively resolves logical problem with accessing
      overloaded non virtual methods from friends.
    + added __clsLock( <hClass> ) - it locks any farther class
      modifications and can be used if programmer wants to be sure
      that no one will try to hack his class definition. It's very
      important when programmers work in a team on bigger project.
      Please do not add to CVS any __clsUnLock() functions - if someone
      needs it then he can create his own custom HVM build.
    * code cleanup

  * harbour/source/vm/eval.c
    + added hb_execFromArray() - idea and syntax borrowed from xHarbour's
      HB_ExecFromArray() by Giancarlo Niccolai though it's independent
      implementation. Now when we have support for functions with variable
      number of parameters then we need sth like this function to fully
      benefit from new feature. The following syntax is supported:
         hb_execFromArray( <cFuncName> [, <aParams> ] )
         hb_execFromArray( @<funcName>() [, <aParams> ] )
         hb_execFromArray( <bCodeBlock> [, <aParams> ] )
         hb_execFromArray( <oObject> , <cMethodName> [, <aParams> ] )
         hb_execFromArray( <oObject> , @<msgName>() [, <aParams> ] )
      or:
         hb_execFromArray( <aExecArray> )
      where <aExecArray> is in one of the following format:
         { <cFuncName> [, <params,...>] }
         { @<funcName>() [, <params,...>] }
         { <bCodeBlock> [, <params,...>] }
         { <oObject> , <cMethodName> [, <params,...>] }
         { <oObject> , @<msgName>() [, <params,...>] }

  * harbour/source/rtl/symbol.prg
    * removed C code inside #pragma BEGINDUMP/ENDDUMP
      now it's only .prg code which uses variable parameters function
      and hb_execFromArray()
