Rlibmemcached exposes a lot of libmemcached internals that will change when upgrading libmemcached, so it should be deprecated before the 2.0 release.
Also, I noticed that memcached_get_from_last and memcached_get_len were removed from libmemcached. The former was only exposed through an Experimental module, so I just removed it. The latter, I deprecated.
@casperisfine please review
