  * include/hbvm.h
  * src/vm/hvm.c
    + added new HVM function: hb_vmTryEval()
      This function tries to execute given block or function
      inside BEGIN SEQUENCE / RECOVER oErr / END SEQUENCE statement.
      It return HB_TRUE if it was executed without any problem and
      HB_FALSE otherwise. Result or RTE object is stored in 1-st
      parameter and should be freed by the caller using hb_itemRelese()

  * src/debug/dbgentry.c
    ! use hb_vmTryEval() instead of hb_itemDo() to evaluate trace point
      expressions. Now debugger does not crash when user sets tracepoint
      expression which cannot be evaluated in executed context.
    ! allow to use expressions with more then 99 variables
    ! added missing protections against GPF when wrong parameters are
      passed to __dbg*() functions
    * keep original trace and watch point expression for farther
      processing
    * replaced IS_IDENT_*() macros with HB_IS*IDCHAR()
    + added new debuger function:
         __dbgGetWatchPoints() -> <aWatchTracePoints>
      <aWatchTracePoints> contains subarrays describing trace and watch
      points:
         { <cExpression>, <lTracePoint>, <lValid>, <xResult> }
      It was the last function necessary to extract all information
      about debugged context from core internals. Now it's possible
      to create fully functional standalone debugger without storing
      and updating locally any information about debugger state.
      All such information can be accessed at any time using __dbg*()
      functions.
      It should greatly simplify creating 3-rd party debuggers like
      HWDebug or HBQTDebug.

  * src/debug/debugger.prg
    ! fixed callstack window updating during tracing and stepping.
      Tanks to Rolf for reporting the problem.
