Tests/simulation testing (#1831)

* Start abstracting all process things.

Will be moving them all behind a trait, this will allow for things like
replay of past events without needing ptrace for breakpoints etc pretty
easily. Just needs a bit of plumbing through things and then hopefully I
can replay failing CI jobs and debug them better!

* Potentially the last bits of plumbing

* Add process offset as well.

* Fix intermittent fork SIGILL error.

In cases where the parent gets the child fork event and not the parents
event and is able to continue the child, halt on the child and continue
it again without getting the parent event we end up with a breakpoint
not being properly reset.

The answer is if a PID is not in the processes map (the initial PID will
be), that means it's a exec'ed or forked process and we can use the
procfs status to get the ppid and autopopulate that as the parent.

I should write a blogpost about this probably...
