Update to version 1.5.  Changes:

** Don't include wchar.h in idn-int.h.
Fixes problems on uClibc systems which lack a wchar.h.  Reported by
Mike Frysinger <vapier@gentoo.org>, see
<http://thread.gmane.org/gmane.comp.gnu.libidn.general/118>.

** Added appendix 'On Label Separators' to the manual.
Thanks to Erik van der Poel <erikv@google.com> for bringing the issue
to our attention and for discussing the matter.  See
<http://thread.gmane.org/gmane.comp.gnu.libidn.general/96>.

** Improved rendering of non-ASCII in the info manual.
Done by adding a @documentencoding UTF-8.  This affect how the
examples are encoded, the files examples/*.c are now encoded using
UTF-8 instead of a mix of ISO-8859-1 and ISO-8859-15.

** Fix non-portable use of brace expansion in makefiles.

** Update translations.

** Update gnulib files.

** API and ABI is backwards compatible with the previous version.
