	PR libfortran/43265
	* io/read.c: Include fbuf.h and unix.h to enable lower level I/O for
	read_x. (read_x): Replace the use of read_sf with equivalent lower level
	I/O, eliminating unneeded code and handling EOF and EOR conditions.
	* io/io.h: Revise prototype for read_sf.
	* io/transfer.c (read_sf): Delete no_error parameter and all uses of it.
	(read_block_form): Likewise.
	(next_record_r): Delete wrong code call to hit_eof.
