74210c12fe Shellbang support with flakes
Enables shebang usage of nix shell. All arguments with `#! nix` get
added to the nix invocation. This implementation does NOT set any
additional arguments other than placing the script path itself as the
first argument such that the interpreter can utilize it.

Example below:

```
    #!/usr/bin/env nix
    #! nix shell --quiet
    #! nix nixpkgs#bash
    #! nix nixpkgs#shellcheck
    #! nix nixpkgs#hello
    #! nix --ignore-environment --command bash
    # shellcheck shell=bash
    set -eu
    shellcheck "$0" || exit 1
    function main {
        hello
        echo 0:"$0" 1:"$1" 2:"$2"
    }
    "$@"
```

fix: include programName usage

EDIT: For posterity I've changed shellwords to shellwords2 in order
      not to interfere with other changes during a rebase.
      shellwords2 is removed in a later commit. -- roberth

Fix boost::bad_format_string exception in builtins.addErrorContext (#9291)
* Fix boost::bad_format_string exception in builtins.addErrorContext

The message passed to addTrace was incorrectly being used as a format
string and this this would cause an exception when the string contained
a '%', which can be hit in places where arbitrary file paths are
interpolated.

* add test

cc46ea1630 Make nix path-info --json return an object not array
Before it returned a list of JSON objects with store object information,
including the path in each object. Now, it maps the paths to JSON
objects with the metadata sans path.

This matches how `nix derivation show` works.

Quite hillariously, none of our existing functional tests caught this
change to `path-info --json` though they did use it. So just new
functional tests need to be added.

937e02e7b9 Shuffle ValidPathInfo JSON rendering
`Store::pathInfoToJSON` was a rather baroque functions, being full of
parameters to support both parsed derivations and `nix path-info`. The
common core of each, a simple `dValidPathInfo::toJSON` function, is
factored out, but the rest of the logic is just duplicated and then
specialized to its use-case (at which point it is no longer that
duplicated).

This keeps the human oriented CLI logic (which is currently unstable)
and the core domain logic (export reference graphs with structured
attrs, which is stable), separate, which I think is better.

ac89bb064a Split up util.{hh,cc}
All OS and IO operations should be moved out, leaving only some misc
portable pure functions.

This is useful to avoid copious CPP when doing things like Windows and
Emscripten ports.

Newly exposed functions to break cycles:

 - `restoreSignals`
 - `updateWindowSize`

9b880e3e29 Factor out MemorySourceAccessor, implement missing features
The new `MemorySourceAccessor` rather than being a slightly lossy flat
map is a complete in-memory model of file system objects.

fetchGit and flake: add publicKeys list input
This adds publicKeys as an optional fetcher input attribute to flakes
and builtins.fetchGit to provide a nix interface for the json-encoded
`publicKeys` attribute of the git fetcher.

Add git commit verification input attributes
This implements the git input attributes `verifyCommit`, `keytype`,
`publicKey` and `publicKeys` as experimental feature
`verified-fetches`. `publicKeys` should be a json string.
This representation was chosen because all attributes must be of type bool,
int or string so they can be included in flake uris (see definition of
fetchers::Attr).

b107431816 Systematize characterization tests a bit more
Deduplicating code moreover enforcing the pattern means:

 - It is easier to write new characterization tests because less boilerplate

 - It is harder to mess up new tests because there are fewer places to
   make mistakes.

1093d6585f Make ParseSink a bit better
I wouldn't call it *good* yet, but this will do for now.

- `RetrieveRegularNARSink` renamed to `RegularFileSink` and moved
  accordingly because it actually has nothing to do with NARs in
  particular.

  - its `fd` field is also marked private

- `copyRecursive` introduced to dump a `SourceAccessor` into a
  `ParseSink`.

- `NullParseSink` made so `ParseSink` no longer has sketchy default
  methods.

This was done while updating #8918 to work with the new
`SourceAccessor`.

f282ef5a56 fix: segfault in positional arg completion
Adding the inputPath as a positional feature uncovered this bug.
As positional argument forms were discarded from the `expectedArgs`
list, their closures were not. When the `.completer` closure was then
called, part of the surrounding object did not exist anymore.

This didn't cause an issue before, but with the new call to
`getEvalState()` in the "inputs" completer in nix/flake.cc, a segfault
was triggered reproducibly on invalid memory access to the `this`
pointer, which was always 0.

The solution of splicing the argument forms into a new list to extend
their lifetime is a bit of a hack, but I was unable to get the "nicer"
iterator-based solution to work.

a419b61497 Turn derivation unit tests into unit characterization tests
The brings a number of advantages, including:

- Easier to update test data if design changes (and I do think our
  derivation JSON is not yet complaint with the guidelines).

- Easier to reuse test data in other implementations, inching closer to
  compliance tests for Nix *the concept* rather than any one
  implementation.
