Merge pull request #2792 from JohnAZoidberg/builtins-hash-file

3f192ac80c Add builtins.hashFile 
For text files it is possible to do it like so:
`builtins.hashString "sha256" (builtins.readFile /tmp/a)`
but that doesn't work for binary files.

With builtins.hashFile any kind of file can be conveniently hashed.

Fix "Bad system call" running i686-linux binaries on x86_64-linux 
To determine which seccomp filters to install, we were incorrectly
using settings.thisSystem, which doesn't denote the actual system when
--system is used.

Fixes #2791.

abbbad5679 Add 'nix list-tarballs' command 
E.g.

  $ nix list-tarballs nixpkgs.hello
  http://tarballs.nixos.org/stdenv-linux/x86_64/4907fc9e8d0d82b28b3c56e3a478a2882f1d700f/bootstrap-tools.tar.xz
  ...
  mirror://gnu/hello/hello-2.10.tar.gz

  $ nix list-tarballs --json -f '<nixpkgs/maintainers/scripts/all-tarballs.nix>'

(BTW the latter returns about 6000 files more than find-tarballs.nix.)

a38a7b495c Use Value::misc to store strings 
This allows strings < 23 characters (up from 16) to be stored directly
in Value. On a NixOS 19.03 system configuration evaluation, this
allows 1060588 out of 1189295 (89%) strings to be stored in Value.

742a8046de Store short strings in Values 
The vast majority of strings are < 16 bytes, and so can be stored
directly in a Value. This saves a heap allocation and an indirection.

2160258cc4 Store contexts as symbols 
This provides some deduplication since most contexts are used multiple
times.

Also, store singleton contexts directly in the Value object. This
saves a 16-byte Context object. This is useful because the vast
majority of contexts are singletons, e.g. 23723 out of 26138 in a
NixOS 19.03 system configuration.

build: only skip hash rewriting for sandboxing on linux 
The sandbox on darwin, and possibly other future platforms, doesn't have
enough isolation to redirect outputs without hash rewriting.

288f93cec0 manual: "Nix Package collection" -> "Nixpkgs package collection". 
Makes difference between Nix and Nixpkgs clearer to avoid
some common confusion this sentence on IRC.

Also disambiguate an "it" reference.

07d9981f34 install-multi-user: remove unneeded settings from nix.conf 
Hardcoding the "max-jobs" and "cores" settings in nix.conf at install
time, to the same value as Nix' built-in default, makes little sense to
me.

dbe4c043d7 install-multi-user: reduce max-jobs from 32 to 1 
Having max-jobs = 32 ($NIX_USER_COUNT is hardcoded to that value) may
severely overload the machine. The nix.conf(5) manual page says max-jobs
defaults to 1, so let's use that value.

NOTE: Both max-jobs and cores are now being set to their default value,
so they can be removed alltogether.

d854e7dfd6 install-multi-user: Detect and fail lack of systemd separately

```
Sorry, I don't know what to do on Linux
```

Which is... not exactly right.
