Summary: No conversion functions between ports and Java I/O types

Initial Comment:
SISC does not offer utility functions to easily convert
between ports and Java I/O types. The following API
should be implemented, as discussed in the sisc-devel
mailing list:

;; 1. InputStream -> <native-input-port>
(define-method (->binary-input-port
  (<java.io.input-stream> is))

;; 2. OutputStream -> <native-output-port>
(define-method (->binary-output-port
  (<java.io.output-stream> os)
  (<boolean> aflush?))
(define-method (->binary-output-port
  (<java.io.output-stream> os))

;; 3. Reader -> <native-character-input-port>
(define-method (->character-input-port
  (<java.io.reader> reader))

;; 4. Writer -> <native-character-output-port>
(define-method (->character-output-port
  (<java.io.writer> writer)
  (<boolean> aflush?))
(define-method (->character-output-port
  (<java.io.writer> writer))

;; 5. <filter-input-port> -> InputStream
(define-method (->jinput-stream
  (<filter-input-port> in-port))

;; 6. <character-input-port> -> InputStream (error)
(define-method (->jinput-stream
  (<character-input-port> in-port))

;; 7. <filter-output-port> -> OutputStream
(define-method (->joutput-stream
  (<filter-output-port> out-port))

;; 8. <character-output-port> -> OutputStream (error)
(define-method (->joutput-stream
  (<character-output-port> out-port))

;; 9. <native-character-input-port> => Reader
(define-method (->jreader
  (<native-character-input-port> in-port))

;; 10. <native-character-output-port> => Writer
(define-method (->jwriter
  (<native-character-output-port> out-port))
