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.

Fix #1314 
Also, make nix-shell respect --option. (Previously it only passed it
along to nix-instantiate and nix-build.)

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").

Benno Fünfstück 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.

Jörg Thalheim 542fe0d8f3 nix-profile.sh: remove sbin from PATH 
sbin is a symlink to bin. 
profiles only contains packages, which have this symlink. 
It is a subset of bin.
