Summary:

Correct some I/O interface inconsistencies regarding what procedures are
available and where they're located.

Description:

There appear to be some funny inconsistencies in the I/O spec.

 * In 15.3.6 (Output ports) there's call-with-bytes-output-port and
call-with-string-output-port, but in 15.3.5 (Input ports) there's no
corresponding call-with-bytes-input-port and call-with-string-input-port.

 * In 15.3.6 (Output ports) and 15.3.5 (Input ports) there's no
call-with-file-output-port or call-with-file-input-port (respectively).

 * In 15.4 (Simple I/O) there's call-with-input-file and
call-with-output-file and with-input-from-file and with-output-to-file.

Recommendations:

 * Add call-with-input-string and call-with-output-string and
with-input-from-string and with-output-to-string to 15.4.

 * Remove call-with-string-output-port from 15.3.6.

 * Add call-with-bytes-input-port to 15.3.5 (or, conversely, remove
call-with-bytes-output-port from 15.3.6).

(An alternative would be to have all appropriate call procedures for files
and strings in 15.3.5 and 15.3.6. At least make the choices consistent.)
