The basic idea here is to separate a few intertwined notions:
1. Not all "run bash tests" are "install tests"
2. Not all "run bash tests" use `tests/functional/init.sh`, or any
pre-test initialization at all.
This will used in the next commit when we have a test that check unit
test golden master data.
Also, move our custom `PS4` from the test to the test runner, as it is
part of how we want to display the tests, not the test themselves.

As discussed in our last meeting, we need a bit more time, but we are
"time boxing" the work left to do to ensure there is not unbounded
delay.
Rather than putting it back underneath `flakes`, though, put it
underneath its own `fetch-tree` experimental feature (which `flakes`
includes/implies). This signals our commitment to the plan to stabilize
it first without waiting to go through the rest of Flakes, and also will
give users a "release candidate" when we get closer to stabilization.
This reverts commit 4112dd1fc9.
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.
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.

update the glossary to point to the new page.
since this is a cross-cutting concern, it warrants its own section in
the manual.

* document the store concept and its purpose
reword the glossary to link to more existing information instead of
repeating it.
move the store documentation to the top of the table of contents, in
front of the Nix language. this will provide a natural place to
document other aspects of the store as well as the various store types.
move the package management section after the Nix language and before
Advanced Topics to follow the pattern to layer more complex concepts on
top of each other.
this structure of the manual will also nudge beginners to learn Nix
bottom-up and hopefully make more likely that they understand underlying
concepts first before delving into complex use cases that may or may not
be easy to implement with what's currently there.
[John adds this note] The sort of beginner who likes to dive straight into reference documentation should prefer this approach. Conversely, the sort of beginner who would prefer the opposite top-down approach of trying to solve problems before they understand everything that is going on is better off reading other tutorial/guide material anyways, and will just "random-access" the reference manual as a last resort. For such random-access the order doesn't matter, so this restructure doesn't make them any worse off.

Rather than having a misc tutorial page in the grab-bag "package management" section, this information should just be part of the S3 store docs.

Single quotes are a basic feature of shell syntax that people expect to
work. They are also more convenient for writing literal code expressions
with less escaping.
this is the first thing most beginners see, and it misleads them into
assuming `nix-env` is appropriate for doing anything but setting and
reverting profile generations.
this chapter is the root of most evil around the ecosystem, and today we
finally close it for good.
* docker: publish images to ghcr.io
docker.com announced their intention to remove the free plan used by
OSS. The nixos/nix image is essential to various CI runs to build with
nix. To provide a continuity plan, this commit pushes the image to
ghcr.io as well.

MemoryInputAccessor is an in-memory virtual filesystem that returns
files like <nix/fetchurl.nix>. This removes the need for special hacks
to handle those files.
Add a new experimental `impure-env` setting that is a key-value list of
environment variables to inject into FOD derivations that specify the
corresponding `impureEnvVars`.
This allows clients to make use of this feature (without having to change the
environment of the daemon itself) and might eventually deprecate the current
behaviour (pick whatever is in the environment of the daemon) as it's more
principled and might prevent information leakage.
For people working on Nix with `nix develop`, it's better to just use
`autoreconfPhase` and `configurePhase`, which is standard Nixpkgs / nix
shell make from Nixpkgs practice --- it is good to emphasize the degree
to which Nix is *just* a regular C++ project which can be worked on in
the regular way.
(For people running `nix-shell`, the story is similar, except
`configurePhase` would use non-writable store paths, which matters for
hte times we use output paths before `make install`, so I kept the
existing `./configure ...` instruction.)
For people building Nix without Nix (e.g. packaging it for another
distro) they also don't need `bootstrap.sh`, and can just run
`autoreconf -vfi` directly. (More likely, they have their own idioms to
do this just as we have `autoreconfPhase`.)
