Partial fix for Issue #443: post-commit hook script (error) output lost
   This is step 2 : Use svn_client_commit_info2_t everywhere
   and the svn_client_create_commit_info() constructor for
   creating svn_client_commit_info2_t objects.

   * subversion/include/svn_client.h
     (svn_client_commit_info_t): Deprecate.

   * subversion/include/svn_client.h
     (svn_client_mkdir, svn_client_delete, svn_client_commit2)
     (svn_client_copy, svn_client_move2): Deprecate.

     (svn_client_mkdir2, svn_client_delete2, svn_client_commit3)

     of the above deprecated functions.

     svn_client_commit_info2_t.
     (svn_client_move3): New version of svn_client_move2(). Now use
     svn_client_commit_info2_t.
     (svn_client_move): Use modified setup_copy().

     svn_client_commit_info2_t while calling svn_client_import2().
     (svn_client_commit3): New version of svn_client_commit2(). Now use
     svn_client_commit_info2_t.
     (svn_client_commit2): Wrap around svn_client_commit3().
