hi.

I'm working on wide char i/o functions like fputwc.
in order to support them, FILE should contain
more data like shift-states.

I made patches to do it, keeping binary compatibility
as far as possible.
we use _ub._base for extension data pointer.
(we can't use _cookie for purpose like this
 since sendmail use it directly. *sigh*)

is this ok to commit?

patches are:
