Add support for downloading crates from a mirror registry.

[zoumi]

I have to use cargo behind a mirror registry, because I can't fully access github.com.
But it seems cargo-vendor can only fetch data from github.com now.

I have tried to build cargo-vendor myself, but it failed. So I'm using the prebuild binary.

The cargo install output:

I'm using mingw-w64 --> i686-5.3.0-posix-dwarf-rt_v4-rev0

[alexcrichton]

Yes currently cargo-vendor (nor Cargo) has a lot of support to download from mirrors. Once Cargo gets it though I can definitely add it to cargo-vendor!

[samanpa]

@alexcrichton Is there a plan to support it now that alternative registries are a thing?

[alexcrichton]

I don't have a ton of time to implement it myself right now but PRs are always welcome!

[alexcrichton]

This crate is now included natively in Cargo as of rust-lang/cargo#6869 and today's nightly Rust. I'm closing all issues in this repository before I archive the repository, but if you're still interested in seeing this issue fixed then please feel free to file an issue with Cargo itself!
