MemcachedClient output a generic error message: "Error parsing memcached
response\n" whenever it is not able to read from the socket. It is also
lacking the remote peer it is reading from.
This patch add a new message when fgets( <socket> ) return false, which
means we could not read from the file pointer. It also get the stream
remote name for debugging purposes.
