+ Added some HB_DBG_*() functions for compatibility
with certain 3rd party libs. They are marked with
HB_LEGACY_LEVEL, and will be removed (pbly at 1.1.0),
so everyone is encouraged to use __DBG*() version
for Harbour versions above 0x010000 (or not use
them at all, if this is possible). If these functions
are indeed needed for some functionality, it'd be
good to hear about it, maybe there is a solution
which doesn't require internals.
