83eec5a997 resolve-system-dependencies: Several fixes
This fixes

  error: getting attributes of path ‘Versions/Current/CoreFoundation’: No such file or directory

when /System/Library/Frameworks/CoreFoundation.framework/CoreFoundation is a symlink.

Also fixes a segfault when encounting a file that is not a MACH binary (such
as /dev/null, which is included in __impureHostDeps in Nixpkgs).

Possibly fixes #786.

canonicalisePathMetaData(): Remove extended attributes / ACLs
EAs/ACLs are not part of the NAR canonicalisation. Worse, setting an
ACL allows a builder to create writable files in the Nix store. So get
rid of them.

Closes #185.

Add a seccomp filter to prevent creating setuid/setgid binaries
This prevents builders from setting the S_ISUID or S_ISGID bits,
preventing users from using a nixbld* user to create a setuid/setgid
binary to interfere with subsequent builds under the same nixbld* uid.

This is based on aszlig's seccomp code
(47f587700d).

Reported by Linus Heckemann.

Fix nix-copy-closure test
Fixes

  client# error: size mismatch importing path ‘/nix/store/ywf5fihjlxwijm6ygh6s0a353b5yvq4d-libidn2-0.16’; expected 0, got 120264

This is mostly an artifact of the NixOS VM test environment, where the
Nix database doesn't contain hashes/sizes.

Add --with-sandbox-shell configure flag
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.

Linux sandbox: Don't barf on invalid paths
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").

75a1d9849d nar-accessor: use tree, fixes readDirectory missing children
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.

Change the meaning of info.ultimate
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).

Add "nix edit" command
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.
