This improves PFAIL -> FAIL switch. Too late at this point in the RC releases to add proper PFAIL/FAIL separate dictionary to do this in a less randomized way. Tested in practice with experiments that this helps. PFAIL -> FAIL average with 20 nodes and node-timeout set to 5 seconds takes 2.5 seconds without this commit, 1 second with this commit.

Otherwise we risk sending not initialized data to other nodes, that may contain anything. This was actually not possible only because the initialization of the buffer where the cluster packets header is created was larger than the 3 gossip sections we use, so the memory was already all filled with zeroes by the memset().

Otherwise it is impossible to receive the majority of failure reports in the node_timeout*2 window in larger clusters. Still with a 200 nodes cluster, 20 gossip sections are a very reasonable amount of bytes to send. A side effect of this change is also fater cluster nodes joins for large clusters, because the cluster layout makes less time to propagate.

On Darwin /dev/urandom depletes terribly fast. This is not an issue normally, but with Redis Cluster we generate a lot of unique IDs, for example during nodes handshakes. Our IDs need just to be unique without other strong crypto requirements, so this commit turns the function into something that gets a 20 bytes seed from /dev/urandom, and produces the rest of the output just using SHA1 in counter mode.

Otherwise between the two commands other nodes may contact us making the next SET-CONFIG-EPOCH call impossible.

If array has N elements, we can't read +1 if we are already at N. Also, we need to move elements by their storage size in the array, not just by individual bytes.

Otherwise kill_instance + restart_instance in short succession will still find the port busy and will fail.
