+ added support for DBI_POSITIONED flag. Because some RDDs may not
support phantom record then checking for EOF() does not have to
be enough to detect that the cursor is positioned to phantom
record. Checking for RecNo() == LastRec() + 1 does not have to
work either because some RDD may use not use continuous record
numbers f.e. ADT. So in code like BROWSE() if you want to be sure
that current record is phantom one then (!dbInfo(DBI_POSITIONED))
should be used.
