Fix deadlock in sys: scheme
...
This patch fixes a deadlock in the sys: scheme that is triggered
when the iostat resource() is called in the same scope where the RwLock
protecting the scheme's handles is write-locked.

Remove deadlock-prone mutex in proc.rs
...
I believe this could cause a deadlock if a blocking I/O operation was
interrupted by a signal or otherwise, and decided to exit and close
all files. It's unlikely to happen, but it can happen nontheless. This
removes the mutex, but it's difficult to keep the code tidy. Hopefully
this is good enough.

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.

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 ;)

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...
