This commit imports the `cargo fix` subcommand in rust-lang-nursery/rustfix
directly into Cargo as a subcommand. This should allow us to ease our
distribution story of `cargo fix` as we prepare for the upcoming 2018 edition
release.
It's been attempted here to make the code as idiomatic as possible for Cargo's
own codebase. Additionally all tests from cargo-fix were imported into Cargo's
test suite as well. After this lands and is published in nightly the `cargo-fix`
command in rust-lang-nursery/rustfix will likely be removed.

Right now the rust-lang/rust integration is compiling Cargo twice on dist
builds, once for Cargo and once for the RLS. This is due to a dependency of
Cargo being recompiled with different features when used from the RLS or not.
For now paper over this problem with a synthetic dependency to prevent Cargo
from being compiled twice.

Reopening of #5129
So, looks like all tests are 🍏 on my machine!
I definitely want to refactor it some more, and also manually checked that we haven't regressed any help messages, but all the major parts are in place already.
This hasn't been updated in awhile and in general we've been barely using it.
This drops the outdated dependency and vendors a small amount of the
functionality that it provided. I think eventually we'll want to transition away
from this method of assertions but I wanted to get this piece in to avoid too
much churn in one commit.
There are some important fixes in jobserver >=0.1.8. With earlier
versions, it's possible for cargo to panic with a "failed to acquire
jobserver token" error, which can be very hard to track down.
Requiring the latest version of jobserver makes sure that no such error
can make it into downstream distributions.
Cargo.toml: Replace '/' with 'OR' in 'license'
Catch up with our recommendations from 7dee65fe (#4898), which deprecated `/` in favor of vanilla SPDX license expressions.
I've gone with the disjunctive `OR`, because the README has:
> Cargo is primarily distributed under the terms of both the MIT license and the Apache License (Version 2.0).

This commit updates the handling of git checkouts from the database to use
hardlinks if possible, speeding up this operation for large repositories
significantly.
As a refresher, Cargo caches git repositories in a few locations to speed up
local usage of git repositories. Cargo has a "database" folder which is a bare
checkout of any git repository Cargo has cached historically. This database
folder contains effectively a bunch of databases for remote repos that are
updated periodically.
When actually building a crate Cargo will clone this database into a different
location, the checkouts folder. Each rev we build (ever) is cached in the
checkouts folder. This means that once a checkout directory is created it's
frozen for all of time.
This latter step is what this commit is optimizing. When checking out the
database onto the local filesystem at a particular revision. Previously we were
instructing libgit2 to fall back to a "git aware" transport which was
exceedingly slow on some systems for filesystem-to-filesystem transfers. This
optimization (we just forgot to turn it on in libgit2) is a longstanding one and
should speed this up significantly!
Closes#4604
