The biggest benefit is that we no longer have to update the registry
package. This means that just about any cargo package can be built by
nix. No longer does `cargo update` need to be feared because it will
update to packages newer then what is available in nixpkgs.
Instead of fetching the cargo registry this bundles all the source code
into a "vendor/" folder.
This also uses the new --frozen and --locked flags which is nice.
Currently cargo-vendor only provides binaries for Linux and
macOS 64-bit. This can be solved by building it for the other
architectures and uploading it somewhere (like the NixOS cache).
This also has the downside that it requires a change to everyone's deps
hash. And if the old one is used because it was cached it will fail to
build as it will attempt to use the old version. For this reason the
attribute has been renamed to `cargoSha256`.

- gcc not needed at all as dependency
- other D compilers can be used instead of dmd, so it's not good to use it as a runtime dependency.
- Adding checkPhase (disabled for now because network access is limited in sandbox mode)
- Improve package description.
"SCons release 3.0.0 now available from the download page at
SourceForge. This release should be used instead of 2.5.1. This release
fixes several issues. TThis will be the first release to support Python
versions earlier than 2.7 as well as 3.5+."
"NOTE: This is a major release. You should expect that some targets may
rebuild when upgrading. Significant changes in some python action
signatures. Also switching between PY 2.7 and PY 3.5, 3.6 will cause
rebuilds."
* Skip verifying checksums for already fetched packages.
Needed for two-staged building in Nix:
1. Build a fixed derivation with `bazel fetch` (filtered out of non-reproducable bits).
2. Build an actual derivation which uses fetched dependencies (skipping
checksums needed here because they depend on the build directory).
* Don't clean environment variables for children processes.
Needed for Nix compiler wrappers.
