qlibc : new package

[Thomas:
 - add dependency on threads, wchar and dynamic librayr
 - add dependency on libiconv when locale support is not enabled
 - replace patch hacking includedir by a patch that lets the Makefile
   obey to $(DESTDIR)
 - remove optional OpenSSL and MySQL support which simply cannot work
   due to the usage of AC_CHECK_FILE() in configure.ac, this required
   an additional patch to fix the bogus AC_ARG_WITH() calls.
 - move from 'Miscellaneous' to 'Libraries' -> 'Other'.
 - fixup the licensing information.]
