Add 'set-port-binary/text-mode!' procedure for MinGW.

Browse source 
* libguile/ports.c (scm_init_ports)[O_BINARY]: Define 'O_BINARY'.
[O_TEXT]: Define 'O_TEXT'.
(scm_c_set_port_binary_text_mode_x): New function.
* libguile/ports.h (scm_set_binary_text_mode_x): Declare it.
* module/ice-9/ports.scm (ice-9): Export it as
'set-port-binary/text-mode!'.
* doc/ref/api-io.texi (File Ports): Document it.

On MinGW, set the binary/text mode for @var{port}. @var{mode} can be one
of the following:
@table @code
@item O_BINARY
binary mode
@item O_TEXT
text mode
@end table
