memcache 7.x-1.0-rc1

Note that while this is a release candidate, session handling is not fully ported yet, there are documented major/critical bugs with core's own session handling so it's unlikely that session handling will be stable prior to 7.x-1.0 final. Testing and useful bug reports for session support welcome!
