Log Message:
qemu: Fix unportable iconv(3) construct breaking on NetBSD

ui_curses.c contains now a new patch:

* Switch unportable iconv(3) UCS-2 <-> wchar_t conversions
  to a portable algorithm with an intermediate step with
  multibyte sequences

With this change qemu -curses works again.

Thanks to joerg@ for pointing out the proper algorithm.

Bump pkgrevision.
