RedoxOS support.

Just small tweaks to make it compile (and run) in RedoxOS!

Works like a charm BTW!

Thank you very much for your contribution!

Do all test run on RedoxOS (cargo test)? I'm wondering because there are a few other places where we have conditionals like #[cfg(unix)].

Thank you for the tool!

Basically we cannot run cargo test inside Redox yet. I basically ran a few manual tests inside Redox and everything seems to be working fine.

Regarding to the cfg uses I've checked and then_execute was the only one I saw with conditional compilation involving Redox I just removed Redox from the two conditionals and Now I think we are using the libstd version of then_execute which is fine as redox has full support. But I dunno I maybe wrong about that removal.

Also in the UNIX libc based version you were importing * from libc which is a lot hehe they thow everything in the root module.

Let me know if the patch still makes sense!

Regards!

Ah BTW none of the other platforms seems to be broken with the patch I think we are safe merging, and I commit to continue iterating on the upcoming issues regarding Redox integration 😄

@mmstick Would you mind taking a quick look at this since you initially introduced the redox conditionals?

Looks okay to me. Redox does have the syscalls needed to be optimized as the Unix platforms though. You just need to grab the same functions from redox_syscalls.
