use rust-lang/libc for types?

[mrhota]

I thought it'd be nicer to use rust-lang/libc's infrastructure for choosing arch-specific types. I think it's possible to link to rust-lang/libc but not link to system libc. Thoughts?

Sorry, mobile fat fingers.

I tried this when I first got started, but I can't remember what blocked me. I think it created a cyclic linker issue for symbols that were defined in the same static library, but I can't remember. I frankly can't remember at the moment whether that would even be an issue for the linker :D.

It looks like it works now. shrug. libstd and friends don't get linked, tests still pass.

Huzzah! I need to look at the diff b/t the libc crate and the platform module for rusl -- I'll put that on my list soon.

@dikaiosune what exactly would you be on the lookout for?

[anp]

I can't remember exactly, but I seem to recall there being a couple of items that I had to change to get desirable semantics on the Rust side (signedness, maybe?). It's probably fine to just go ahead and switch things over, assuming tests pass.
