Working on isue #4326 (update javahl with new 1.8 APIs).

[in subversion/bindings/javahl/native]
* ListCallback.h, ListCallback.cpp (ListCallback::callback):
   Update prototype to match svn_client_list_func2_t.
* SVNClient.cpp (SVNClient::list): Call svn_client_list3
   instead of svn_client_list2.
  (SVNClient::commit): Call svn_client_commit6 so that
   behaviour does not change from the deprecated svn_client_commit5.

[in subversion/bindings/javahl/src/org/apache/subversion/javahl/callback]
* ListCallback.java (ListCallback): Fix link in docstring.
