The profile manifest is now an object keyed on the name returned by
getNameFromURL() at installation time, instead of an array. This
ensures that the names of profile elements don't change when other
elements are added/removed.
* document `fetchTree`
* display experimental feature note at the top
we have to enable the new `fetchTree` experimental feature to render it
at all. this was a bug introduced when adding that new feature flag.

* Factor out the default `MultiCommand` behavior
All the `MultiCommand`s had (nearly) the same behavior when called
without a subcommand.
Factor out this behavior into the `NixMultiCommand` class.
* Display the list of available subcommands when none is specified
Whenever a user runs a command that excepts a subcommand, add the list
of available subcommands to the error message.
* Print the multi-command lists as Markdown lists
This takes more screen real estate, but is also much more readable than
a comma-separated list
This makes for more useful manual table of contents, that displays the
information at a glance.
The `nix help-stores` command is kept as-is, even though it will show up
in the manual with the same information as these pages due to the way it
is written as a "`--help`-style" command. Deciding what to do with that
command is left for a later PR.
This change also lists all store types at the top of the respective overview page.

- helps navigating the code as it highlights which files are generated
- makes it less error prone when working incrementally
(although this should be just fixed by building out of tree)
This builds on #8817, to add additional UX help for people with existing
muscle memory (or shell history) with --update-input and tries to gently
guide them towards the newly evolved CLI UI.

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
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.
`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.
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`
