* Remove obsolete backport proposal.

        Trunk version of patch works

     +1: rpluem, jim

   * proxy_util: Make the connection timeout to backends work by temporarily

     setting the socket to non blocking mode.

     Trunk version of patch:

        http://svn.apache.org/viewvc?rev=703998&view=rev

     Backport version for 2.2.x of patch:

        Trunk version of patch works

     -1: rpluem: apr_socket_timeout_set already sets the socket to non-blocking

         mode because the timeout of the socket is -1 after creation. A further

         call to apr_socket_timeout_set (after the connect call does not do

         this, because the old and the new timeout are >=0).

         The further code expects the socket to be in non-blocking mode, otherwise

         we have regressions with ssl. This can be notified by running t/ssl/proxy

         which runs much much slower with the patch applied. This does not happen

         on trunk because the socket is set back to non blocking by the core

         output filter (async write completion).

         So r703998 should be also reverted on trunk.

   * mod_rewrite: Export and install the mod_rewrite.h header to ensure the

     optional rewrite_mapfunc_t and ap_register_rewrite_mapfunc functions are

     available to third party modules.
