Initial work on Fuzzer randomization

[playX18]

Resolves #3988.

Notes

At the moment this PR contains simple implementation, I am still working on making this randomization better. At the moment some runs show success rates of 80-90% and others show 30%. Coverage is also increased but ever so slightly, I am guessing more testing with syscall injections is needed but for this I need to figure out how to randomize them properly.

@techraed request for review now. I've adjusted parameters to match master fuzzer success/failure rate and potentially have better success rate. Still need to verify this on dedicated server though

@techraed

Great!!!

What's with checks on a server - is everything satisfiable?

As we discussed in DM compared to master this branch runs 10-15x more programs compared to master

	master	ap/random-fuzzer
Success	14795	256865
Traps	19246	110748

Also as you can see we beat success rate of master fuzzer which is a significant improvement.

• ap/random-fuzzer: 69.87% success, 30.12% traps
• master: 43.46% success, 56.53% traps

EDIT: fix numbers
