channels make everything more stateful, and therefore more complicated
and potentially confusing, but aren't needed for this task, so don't encourage their use.
* deduplicate installation instructions
- reorder sections to present pinned installation more prominently
- remove outdated notes on the macOS installer rework
- update instructions to handle the installer tarball

It might seem obnoxious to have yet more configure flags, but I found
controlling both the unit and functional tests with one flag was quite
confusing because they are so different:
- unit tests depending on building, functional tests don't (e.g. when
we test already-built Nix)
- unit tests can be installed, functional tests cannot
- unit tests neeed extra libraries (GTest, RapidCheck), functional
tests need extra executables (jq).
- unit tests are run by `make check`, functional tests are run by `make
installcheck`
Really on a technical level, they seem wholly independent. Only on a
human level ("they are both are tests") do they have anything in common.
I had messed up the logic in cross builds because of this. Now I
split the flag in two (and cleaned up a few other inconsistencies), and
the logic fixed itself.

* 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.

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`.)
e.g. nix-env -e subversion => nix-env --uninstall subversion
The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.
The change was made with the following script:
<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>
and sanity checked visually.
`/etc/bash.bashrc` is backed up as `/etc/bash.bashrc.backup-before-nix`,
but since other changes might have been introduced in the meantime we can't
just tell the user to revert.
placed in a subsection of the binary install, the instructions are hard
to find. putting them in a separate page that is shown in the table of
contents should make it easier for users to find what they need when
they need it.
This provides a platform-independent way to configure the SSL
certificates file in the Nix daemon. Previously we provided
instructions for overriding the environment variable in launchd, but
that obviously doesn't work with systemd. Now we can just tell users
to add
ssl-cert-file = /etc/ssl/my-certificate-bundle.crt
to their nix.conf.
Before #5150 the copy-to-store phase of the install was idempotent,
but the recursive cp isn't. This is probably baiting a few people
into trying corrective installs that will fail.
The uninstall instructions used to accidentally remove the nix-darwin
LaunchDaemon, this was dropped. However, the original intent was to
remove the Store volume mounting LaunchDaemon.
Clarify that `/nix` being present after the uninstall is normal and it
will only disappear after a reboot.

The multi-user installation on macOS, which is now the only option, has
gotten complicated enough that it discourages some users from checking
Nix out for fear of being left with a "dirty" system. Detailed
uninstallation instructions should make this less of an issue.
