Update to 1.10:

* Version 1.10 (released 2008-08-27)

** idn: accept -n as short form for --nfkc.
Before '-k' was used as the short form, but all documentation has said
'-n'.  We now accept both short forms, and -n remains the documented
short form.  Reported by John McGowan <jmcgowan@inch.com> in
<http://lists.gnu.org/archive/html/help-libidn/2008-08/msg00000.html>.

** Fix compiler warnings.

** Update gnulib files.

** Update translations.

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