Update to 1.12:

* Version 1.12 (released 2009-01-23)

** idn: New parameter --no-tld to deprecate the old parameter --tld.
The new parameter --no-tld disable TLD checking of the input string.
The --tld parameter was broken; it behaved opposite to its documented
behaviour.  To avoid confusion over what --tld means, we decided to
deprecate it.  Now --tld is not printed in the idn --help output, but
will continue to work as before.

** doc: Modernize doxygen configuration.

** doc: Change license on the manual to GFDLv1.3+.

** doc: Improve JavaDoc output.

** Update gnulib files and translations.

** Build with more warnings.
