Yet another revision of this algo... yeesh... and update to supernode IDs. I think I am gonna go with this one. Seems memory-hard enough to me. I am probably procrastinating by obsessing over it.

Make Salsa20 variable-round, allowing for Salsa20/12 to be used for Packet encrypt and decrypt. Profiling analysis found that Salsa20 encrypt was accounting for a nontrivial percentage of CPU time, so it makes sense to cut this load fundamentally. There are no published attacks against Salsa20/12, and DJB believes 20 rounds to be overkill. This should be more than enough for our needs. Obviously incorporating ASM Salsa20 is among the next steps for performance.

Another tweak, hopefully final, to reduce variance on identity generation times.

Old algo for ID derivation was not in fact memory-hard since Salsa20 is seekable, so take two.
