Subject: [PATCH] New configure flag: --enable-deprecated

By default we don't compile in the deprecated interface (so that continuing
to use it will be a bit more painful ;-) I had to create a new file to keep
track of the #defines, because the clients of libmemcached doesn't see
libmemcached_config.h.
