Centralize the creation of port objects based on stdio FILE * in

Browse source 
fports.c; don't just throw them together anywhere.
* fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
what the rest of Guile wants.  Don't set the revealed count;
that's only appropriate for stdin, stdout, stderr.
(scm_standard_stream_to_port): This function does set the revealed
count.
* init.c (scm_init_standard_ports): Use	scm_standard_stream_to_port,
not scm_stdio_to_port.
* filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
* fports.c (scm_open_file): Same.
* posix.c (scm_pipe): Same.
* socket.c (scm_sock_fd_to_port): Same.
* ioext.c (scm_fdopen): Same.
(scm_freopen): Moved from here to...
* fports.c (scm_freopen): ... here.  This is really something that
munges the internals of an fport, so it should go here.
* fports.h (scm_stdio_to_port): Adjust prototype.
(scm_standard_stream_to_port, scm_freopen): New protoypes.
* ioext.h (scm_freopen): Prototype removed.
* filesys.c (set_element, get_element): This can work on both pipe
and file ports, so use SCM_FPORTP to typecheck, instead of testing
for scm_tc16_fport.
