Andreas Rammhold 0c50140da5 buildRustCrate: add heuristic to picking the right source files
Cargo has a few odd (old) ways of picking source files if the `bin.path`
attribute isn't given in the Cargo.toml. This commit adds support for
some of those. The previous behaviour always defaulted to `src/main.rs`
which was not always the right choice.

Since there is  look-ahead into the unpacked sources before running the
actual builder the path selection logic has to be embedded within the
build script.

`buildRustCrate` currently supports two ways of running building
binaries when processing a crate:

- Explicit definition of all the binaries (& optionally the paths to
their respective `main.rs`) and,
- if not binary was explictly configured all files matching the patterns
  `src/main.rs`, `src/bin/*.rs`.

When the explicit list is given without path information paths are now
being picked from a list of candidates. The first match wins. The order
is the same as within the cargo compatibility code.

If the crate does not provide any libraries the path `src/{bin_name}.rs`
is also considered.

All underscores within the binary names are translated into dashes (`-`)
before the lookups are made. This seems to be a common convention.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels https://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-18.03 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-18.03

For pull-requests, please rebase onto nixpkgs master.

NixOS Linux distribution source code is located inside nixos/ folder.
