Memcached: protect from too long responses. If a memcached response was followed by a correct trailer, and then the NUL character followed by some extra data - this was accepted by the trailer checking code. This in turn resulted in ctx->rest underflow and caused negative size buffer on the next reading from the upstream, followed by the "negative size buf in writer" alert. Fix is to always check for too long responses, so a correct trailer cannot be followed by extra data.
