I switched over to the getopts crate on crates.io, instead of Rust's
private implementation. This will allow coreutils to build for Rust 1.0.
I'm splitting the updates into several commits for easier reviewing.

Aside from the usual upgrades to sync with the nightly build, I fixed an
unwrap() panic when reading lines with only a newline. I also refactored
the repeated command calls to use helper functions.
With this change, individual submodules can specify their dependencies with
an additional file called "deps.mk" in the subdir. When building, only
the dependencies that are necessary are built, using cargo, and then linked.
This greatly simplifies adding new dependencies: add the package in
deps/Cargo.toml, and add the appropriate line in "deps.mk" in the
src/utilname/ directory, and the dependency will be built automatically
as needed.
This also removes the need to use git submodules.
