Extend svn_wc_info_t with an array of svn_wc_conflict_description3_t items.
This will allow the svn client to use conflict descriptions of this type.

* subversion/include/svn_wc.h
  (svn_wc_info_t): Add 'conflicts2'.

* subversion/libsvn_wc/info.c
  (svn_wc_info_dup): Duplicate the new svn_wc_conflict_description3_t array.
  (build_info_for_node): Populate the svn_wc_conflict_description3_t array.
