* harbour/include/hbvm.h
* harbour/source/vm/hvm.c
+ added void hb_vmAtQuit( HB_INIT_FUNC pFunc, void * cargo );
AtQuit functions are executed after deallocating all HVM items and
disabling .prg destructors. They can make final cleanup at C level
but should not reenter HVM.
* harbour/contrib/hbole/oleinit.c
* use hb_vmAtQuit() instead of hb_vmAtExit() - it resolves the problem
with executing destructors to OLE objects after closing OLE connection.
* harbour/contrib/hbole/olecore.c
+ added translation for VT_R4 and VT_CY values.
! fixed MT support by moving OLE error code to TSD
