jD91mZM2 039f7f5c83 Simplify EXEC catching
Instead of having a separate flag, let's reuse STOP_SINGLESTEP :)

I wasn't thinking enough when making this flag!

jD91mZM2 a7da393cf5 WIP(ptrace): Better support for signals
Signals now cause an event, and there's a way to continue until the
next signal. I can see this being used for detection of `int3`
although I'm not entirely sure as it may prove being too late to stop
abortion of process.

Jeremy Soller 788526a3b3 Bare-bones ptracing functionality
Since even a very basic ptrace can be nice to have, I thought I would split
the, perhaps rather big, ptrace project up in multiple PRs to make as few
changes as necessary in each. This PR contains the initial registry modifying
bits and only a very basic security measure. Letting this out to the community
should be good for spotting bugs and maybe getting some hype ;)

jD91mZM2 effe02bd45 Remove change I am faaairly certain I did NOT add :O

jD91mZM2 fe705d9b63 Switch to 2018 edition
Most of this was generated by the absolutely extraordinary `cargo fix`
subcommand. There were still 2 errors and a few warnings to patch up,
but compared to the normal 600+ errors, I'd say the fixer did a damn
good job! I'm also amazed that I could still start the VM after this,
I half expected some kinds of runtime failure...
