	PR libfortran/43265
	* io/io.h: Delete prototype for read_sf, making it static.
	* io/read.c (read_x): Modify to call hit_eof if PAD="no".
	* io/transfer.c (read_sf_internal): New static function extracted from
	read_sf for use on internal units only. Handle empty string case.
	(read_sf): New factoring of this function, make it static.  Add special
	conditions for EOF based on ADVANCE="no", PAD="no", and whether any
	bytes have been previously read from the record.
	(read_block_form): Modify to call read_sf or read_sf_internal.
	(next_record_r): Add a done flag similar to next_record_w. Call hit_eof
	if internal array unit next record returns finished, meaning an EOF was
	found and not done, ie not the last record expected.  For external
	units call hit_eof if item_count is 1 or there are no pending spaces.
	(next_record): Update call to next_record_r.
