This makes the deny(warnings) in the testsuite conditional on a new
"deny-warnings" feature, that is then enabled in CI.
Ideally I could use the (reasonably well established) CI env var (like
we do for proptests), but I don't know how to get the attribute to be
defined in terms of an env var.
Previously build scripts were accidentally and unconditionally compiled with the
2015 edition, but they should instead use the edition of the `[package]` itself.

* Collapse the nested cargotest::support module into the cargotest
module (merge the mod.rs's)
* Rename the cargotest module to support
* Nest the top-level hamcrest module into support
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.

Notes:
- `-Z config-profile` CLI option is required to use.
- Config values no longer reject mixed base types (integer, string, boolean) in order to support the mixed types in profiles.
With 'cargo build --build-plan', cargo does not actually run any
commands, but instead prints out what it would have done in the form of
a JSON data structure.
Fixes#3815
This commit is directed at fixing #4127, allowing the resolver to automatically
perform transitive updates when required. A few use casese and tagged links are
hanging off #4127 itself, but the crux of the issue happens when you either add
a dependency or update a version requirement in `Cargo.toml` which conflicts
with something listed in your `Cargo.lock`. In this case Cargo would previously
provide an obscure "cannot resolve" error whereas this commit updates Cargo to
automatically perform a conservative re-resolution of the dependency graph.
It's hoped that this commit will help reduce the number of "unresolvable"
dependency graphs we've seen in the wild and otherwise make Cargo a little more
ergonomic to use as well. More details can be found in the source's comments!
