This yields an enormous speed boost (almost 10x more exections per second on my machine)
This addresses most of the non-determinism

This PR makes use of the changes in int08h/roughenough#11 to add a server fuzzing target.
I've based this PR off my branch from #1, so not all of the commits are unique to this PR.
Unfortunately, enabling 'AFL persistent mode' (using
afl::fuzz) causes the AFL 'stability' statistic to drop to around 70%. Even when using 'non-persistent' mode (usingafl::read_stdio_bytes), the 'stability' is only reaches 97%.Because of this, I'm marking this PR as WIP until I can figure out the cause of the non-determinism. In theory, the server should be completely deterministic, since
process_eventsshouldn't depend on any state from previous executions.
