description:
Pull up following revision(s) (requested by mrg in ticket #1303):
        lib/libc/stdio/funopen.c: revision 1.15
PR/51572: calling funopen on each printw call is a tad excessive, but this
is not a reason for funopen to leak. Always call the close function since we
are indirecting through our cookie and we need to free it.
