Oracle DB scroll cursor emulation removal

The scroll cursor emulation has been removed in the Oracle® DB driver.

Before Genero 3.00, it was possible to enable scrollable cursor emulation (with temporary files) by defining the following FGLPROFILE entry:

dbi.database.mydbname.ora.cursor.scroll.emul = true

This feature was supported to workaround an Oracle DB bug in versions 8 and 9i. The bug no longer exist in recent Oracle DB versions and therefore the default native scrollable cursor feature can be safely used.

If this FGLPROFILE entry is set, the runtime system will print a warning to stderr.
