Assign an unique non-repeating ID to each new client.

This will be used by CLIENT KILL and is also a good way to ensure a

The output of CLIENT LIST was modified to include the new ID, but this
change is considered to be backward compatible as the API does not imply
you can do positional parsing, since each filed as a different name.
