And add a 116 KiB ash shell from busybox to the release build. This
helps to make sandbox builds work out of the box on non-NixOS systems
and with diverted stores.
This is useful when we're using a diverted store (e.g. "--store
local?root=/tmp/nix") in conjunction with a statically-linked sh from
the host store (e.g. "sandbox-paths =/bin/sh=/nix/store/.../bin/busybox").
Previously, if a directory `foo` existed and a file `foo-` (where `-` is any character that is sorted before `/`), then `readDirectory` would return an empty list.
To fix this, we now use a tree where we can just access the children of the node, and do not need to rely on sorting behavior to list the contents of a directory.
It now means "paths that were built locally". It no longer includes
paths that were added locally. For those we don't need info.ultimate,
since we have the content-addressability assertion (info.ca).
This is a little convenience command that opens the Nix expression of
the specified package. For example,
nix edit nixpkgs.perlPackages.Moose
opens <nixpkgs/pkgs/top-level/perl-packages.nix> in $EDITOR (at the
right line number for some editors).
This requires the package to have a meta.position attribute.
Replace urfave/cli with the kingpin[1] library.
It has slightly more sensible argument validation than the other Go libraries.
Additionally I've opted for removing the '-f / --file' flag in favour of positional arguments to commands.
A previous command like `kontemplate template -f somefile.yml` is now just `kontemplate template somefile.yml`. All other arguments remain the same.

After filtering resource sets, check whether any resource sets "survived".
Otherwise it can be assumed that the user specified invalid exclude/include
combinations and should be warned about that.
Fixes#35
There is a security issue when a build accidentally stores its $TMPDIR
in some critical place, such as an RPATH. If
TMPDIR=/tmp/nix-build-..., then any user on the system can recreate
that directory and inject libraries into the RPATH of programs
executed by other users. Since /build probably doesn't exist (or isn't
world-writable), this mitigates the issue.
