Jack1 and Jack2 are alternative implementations with different
advantages and disadvantages (depending on hardware and use-case).

Despite its name, Jack2 is not really the successor to Jack1, so I think
it would be better to keep "jack" as is, and add "jack2" as a separate
recipe.

Note that Jack2 runs in so-called asynchronous mode by default, which
adds a bit of latency (at the same buffer size), and also influences the
way xruns are reported.
Both versions will require modifications to /etc/security/limits.conf in
order to use realtime (FIFO) scheduling, which is crucial for low latencies.
