Update Cargo and its dependencies

[alexcrichton]

This'll probably have a bunch of build errors, so let's try and head those off
and find them sooner rather than later!

Thanks for working on this! Including cc 1.0.4 is going to be pretty useful for me to get automated builds for CloudABI to work.

[alexcrichton]

I think that should be fixed w/ rust-lang/cargo#4926 (and hopefully good to go afterwards)

Travis is green, so r=me after fixing the merge conflict (and let the actual debugging begin 😄).

Same error.

[retep998]

It's building the things using stage0 and that stage doesn't yet have the fix of those two import libraries in the sysroot.

[kennytm]

Ah. Could we build them using stage2? (If stage0 can't be fixed)

[Mark-Simulacrum]

I would prefer that we don't move anything to later stages because stage 0 doesn't work; if this is a bug in stage 0, we can backport and bump the bootstrap compiler or workaround it temporarily, I think. However, if there's no other solution, moving to stage 2 compilation should be relatively painless.

[alexcrichton]

I've confirmed that the master branch of winapi builds cleanly (no env vars set) with MinGW due to the use of prefixed libraries. Due to other bugs however we can't actually use [patch] to depend on git repositories (it fails distcheck), @retep998 would you be able to make a release soon?

[retep998]

@alexcrichton You will still need to set one of those environment variables though in order to avoid issues with external projects that depend on rustc internal crates failing to link because they can't find winapi's prefixed libraries. I've published new versions now.
