libutil/logging: extend internal-json logger to make it more machine-readable
The new error-format is pretty nice from a UX point-of-view, however
it's fairly hard to parse the output e.g. for editor plugins such as
vim-ale[1] that use `nix-instantiate --parse` to determine syntax errors in
Nix expression files.

This patch extends the `internal-json` logger by adding the fields
`line`, `column` and `file` to easily locate an error in a file and the
field `raw_msg` which contains the error-message itself without
code-lines and additional helpers.

An exemplary output may look like this:

```
[nix-shell]$ ./inst/bin/nix-instantiate ~/test.nix --log-format minimal
{"action":"msg","column":1,"file":"/home/ma27/test.nix","level":0,"line":4,"raw_msg":"syntax error, unexpected IF, expecting $end","msg":"<full error-msg with code-lines etc>"}
```

Samir Talwar 9069759767
Instruct the user to follow redirects when installing Nix.
Nix installation now requires following redirects using `curl -L`. This
is currently represented on the [Nix download page][] but not in the
manual. This change updates the manual to reflect this.

Using `curl` without the `-L` flag results in an empty body, making
installation a no-op.

focus on golden-path covering most scenarios
This should handle installation scenarios we can handle with
anything resembling confidence. Goal is approximating the existing
setup--not enforcing a best-practice...

Approaches (+ installer-handled, - manual) and configs each covers:

+ no change needed; /nix OK on boot volume:
  All pre-Catalina (regardless of T2 or FileVault use)

+ create new unencrypted volume:
  Catalina, pre-T2, no FileVault

+ create new encrypted-at-rest volume:
  Catalina, pre-T2, FileVault
  Catalina, T2, no FileVault

- require user to pre-create encrypted volume
  Catalina, T2, FileVault

Remove -j option from simple-build-testing
By default Nix/NixOS already set a reasonable default `max-jobs = auto`
so we don't need to mention it in this tutorial.
The option is still documented in other parts of the documentation
if users ever stumble over this.

Update "Upgrading Nix" documentation
This PR proposes two changes to the "Upgrading Nix" documentation:

* Besides updating `nixpkgs.nix`, we also update `nixpkgs.cacert`, so that the certificates are up-to-date as well.
* Add the instructions for multi-user mode on Linux.

add NIX_USER_CONF_FILES
Motivation: maintain project-level configuration files.

Document the whole situation a bit better so that it corresponds to the
implementation, and add NIX_USER_CONF_FILES that allows overriding
which user files Nix will load during startup.

Greg Price e40e01c1dd doc: Files in the store have modes 444/555, not 644/755
This line has been this way since it was written, in 9e08f5efe
in 2006.

I think it was just a small mistake then; Eelco's thesis earlier
that year says the permission on each file is set to 0444 or 0555
in a derivation's output as part of the build process.  In any
case I'm pretty sure that's the behavior now.

jakobrs c5a488afc0 Remove the --delete option for --gc
Running `nix-store --gc --delete` will, as of Nix 2.3.3, simply fail
because the --delete option conflicts with the --delete operation.

  $ nix-store --gc --delete
  error: only one operation may be specified
  Try 'nix-store --help' for more information.

Furthermore, it has been broken since at least Nix 0.16 (which was
released sometime in 2010), which means that any scripts which depend
on it should have been broken at least nine years ago. This commit
simply formally removes the option. There should be no actual difference
in behaviour as far as the user is concerned: it errors with the exact
same error message. The manual has been edited to remove any references
to the (now gone) --delete option.

Other information:
* Path for Nix 0.16 used:
  /nix/store/rp3sgmskn0p0pj1ia2qwd5al6f6pinz4-nix-0.16

style.css: Remove
This file is licensed under the GPL. Originally, Nix was also
GPL-licensed so that was fine. However, we later changed the license
to the LGPL but missed the fact that style.css has an incompatible
license.

Since the Nix manual at nixos.org uses its own styling, we can remove
this file.

Fixes #3392.

- At the top of the release notes, we announce sandboxing is now enabled by default,

can be merged into one point for clarity.

- The point about `max-jobs` defaulting to 1 appears unrelated to sandboxing.

Track function start and ends for flame graphs
With this patch, and this file I called `log.py`:

    #!/usr/bin/env nix-shell
    #!nix-shell -i python3 -p python3 --pure

    import sys
    from pprint import pprint

    stack = []
    timestack = []

    for line in open(sys.argv[1]):
        components = line.strip().split(" ", 2)
        if components[0] != "function-trace":
            continue

        direction = components[1]
        components = components[2].rsplit(" ", 2)

        loc = components[0]
        _at = components[1]
        time = int(components[2])

        if direction == "entered":
            stack.append(loc)
            timestack.append(time)
        elif direction == "exited":
            dur = time - timestack.pop()
            vst = ";".join(stack)
            print(f"{vst} {dur}")
            stack.pop()

and:

    nix-instantiate --trace-function-calls -vvvv ../nixpkgs/pkgs/top-level/release.nix -A unstable > log.matthewbauer 2>&1
    ./log.py ./log.matthewbauer > log.matthewbauer.folded
    flamegraph.pl --title matthewbauer-post-pr log.matthewbauer.folded > log.matthewbauer.folded.svg

I can make flame graphs like: http://gsc.io/log.matthewbauer.folded.svg

---

Includes test cases around function call failures and tryEval. Uses
RAII so the finish is always called at the end of the function.

conf: stalled-download-timeout: make tunable
Make curl's low speed limit configurable via stalled-download-timeout.
Before, this limit was five minutes without receiving a single byte.
This is much too long as if the remote end may not have even
acknowledged the HTTP request.

Add a post-build-hook
Passing `--post-build-hook /foo/bar` to a nix-* command will cause
`/foo/bar` to be executed after each build with the following
environment variables set:

    DRV_PATH=/nix/store/drv-that-has-been-built.drv
    OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev

This can be useful in particular to upload all the builded artifacts to
the cache (including the ones that don't appear in the runtime closure
of the final derivation or are built because of IFD).

This new feature prints the stderr/stdout output to the `nix-build`
and `nix build` client, and the output is printed in a Nix 2
compatible format:

    [nix]$ ./inst/bin/nix-build ./test.nix
    these derivations will be built:
      /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv
    building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'...

Niklas Hambüchen 57daa860e8 autoconf: Fix C++17 detection not working on Ubuntu 16.04.
And probably many other distributions.

Until now, ./configure would fail silently printing a warning

    ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found

and then continuing, later failing with a C++ #error saying that some C++11
feature isn't supported (it didn't even get to the C++17 features).

This is because older distributions don't come with the
`AX_CXX_COMPILE_STDCXX_17` m4 macro.

This commit vendors that macro accordingly.

Now ./configure complains correctly:

    configure: error: *** A compiler with support for C++17 language features is required.

On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with
gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test
using:

    ./bootstrap.sh
    ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)

Niklas Hambüchen 1f97b16b1d autoconf: Work around editline not being found on Ubuntu 16.04.
And probably other Linux distributions with long-term support releases.

Also update manual stating what version is needed;
I checked that 1.14 is the oldest version with which current nix compiles,
and added autoconf feature checks for some functions added in that release
that nix uses.

doc: clarify that optional attrs in a function argument will be ignored unless specified
In `args@{ a ? 1 }: /* ... */` the value `a` won't be a part of `args`
unless it's specified when calling the function, the default value will
be ignored in this case.

My personal point of view is that this behavior is a matter of taste, at
least I was pretty sure that unmatched arguments will be a part of
`args@` while debugging some Nix code last week.

I decided to add a warning to the docs which hopefully reduces the
confusion of further Nix developers who thought the same about `args@`.

Daniel Schaefer 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.
