	Backport from mainline
	PR libfortran/58324
	PR libfortran/38199
	* io/list_read.c (finish_list_read): Read one character to check
	for the end of the file.  If it is the end, then issue the file
	end error message.  If not, use eat_line to reach the end
	without giving error.  The next attempt to read will then
	issue the error as described above.
	* io/read.c (read_decimal): Quickly skip spaces to avoid calls
	to next_char.
	* io/unit.c (is_trim_ok): New helper function to check various
	conditions to see if its OK to trim the internal unit string.
	(get_internal_unit): Use LEN_TRIM to shorten selected internal
	unit strings for optimizing READ. Enable this optimization for
	formatted READ.
