The function set_form_opts sets all the given form's option bits (form
option bits may be logically-OR'ed together).
The function form_opts_on turns on the given option bits, and leaves
others alone.

others alone.
The function form_opts returns the form's current option bits.
The following options are defined (all are on by default):
O_NL_OVERLOAD
Overload the REQ_NEW_LINE forms driver request so that calling it
at the end of a field goes to the next field.
O_BS_OVERLOAD
Overload the REQ_DEL_PREV forms driver request so that calling it
at the beginning of a field goes to the previous field.
RETURN VALUE
Except for form_opts, each routine returns one of the following:
E_OK The routine succeeded.
E_SYSTEM_ERROR
System error occurred (see errno(3)).
