Agreed, I was just thinking that also. We're overcomplicating this. We 
don't need read/write/close on files; we can just export stuff like
_dbus_file_get_contents
_dbus_create_empty_file_exclusively
_dbus_file_set_contents

and other high-level operations.

You could try to just get rid of all uses of read/write/close on files 
(outside of -unix.c/-win.c), replacing them with functions like the 
above (first patch), then (second patch) rename read/write/close/poll to 
be read_socket, write_socket, close_socket. I think it would be fine to 
keep the socket as "int" instead of a DBusSocket, since it's an int on 
both platforms, and we won't have a file int in the api at all.
