As pointed in rust-lang#633, it's currently not possible for a package to reexport the feature of another package due to the limitations of how features are defined. This commit adds support for this ability by allowing features of the form `foo/bar` in the `features` section of the manifest. This form indicates that the dependency `foo` should have its `bar` feature enabled. Additionally, it is not required that `foo` is an optional dependency. This does not allow features of the form `foo/bar` in a `[dependencies]` features section as dependencies shouldn't be enabling features for other dependencies. Closes rust-lang#633 Closes rust-lang#674
Closes rust-lang#97 Closes rust-lang#601 (this is an equivalent solution for that problem)

This series of commits is rebased on top of #712 to avoid conflicts, and it adds the ability to solve version constraints as part of the resolution process. This is a critical step forward in bringing the registry online as it makes it possible for cargo to figure out what to do in the face of many uploaded versions of a package to the registry. r? @wycats

The cleaner way is to take advantage of the single-dependency-deep "slashed features" support in Cargo.toml to set features of direct dependencies (not affecting recursive depnedencies) as implemented in rust-lang/cargo#712
