Previously many of the documentation targets were depending on
`$(bindir)/nix` which is the installed version. This meant that its
install rules would be triggered (which in chain would also trigger the
install of libraries, as reported in #5140). Therefore a build of the
documentation without an installation would not be possible (which apart
from doing unwanted operations it may also generate permission problems
for example).
The fix makes the rules depend on `$(nix_PATH)` instead, which is the
executable in the build tree.
The problem was that f880469173 forgot
that the `#include <sys/xattr.h>` was guarded by an `#ifdef __linux__`.
However, the build failure was only on FreeBSD --- turns out other
platforms have this header too!
The fix therefore uses a new configure check so we properly clear ACLs
on more platforms.
This allows templates such as `NLOHMANN_DEFINE_TYPE_*` templates and other generators with things like `std::vector<std::optional<T>>`.

`installcheck` doesn't yet work, but the rest of the build can now
happen mostly inside a separate build directory.
Progress on #9342

In commit 0d2163c6dc, the progress bar was hidden
in nix repl because of a regression that caused it to interfere with user
input. Several users like(d) seeing the progress bar in the repl during builds.
Only hiding it while waiting for user input gives us the best of both worlds,
so do just that.
Without the change build for `eval.o` fails occasionally as:

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.

up to now, those were managed outside of this repo, which as
unsurprisingly a real hassle to deal with if one wanted to prevent URLs
from breaking when moving pages around. this change removes a large part
of the friction involved in moving content in the Nix manual.
possible next steps for further automation:
- check for content that moved and warn if it's not reachable from
links that were valid prior to a change
- create redirect rules automatically based on this information
We occasionnally commit to git repositories (like with `nix flake update --commit-lock-file`).
This shells out to `git commit`, which might wait for user input (for a signing key passphrase for instance).
Disable the progress bar while this is running to make sure that the
user can enter it.
* doc: primops: add more info for foldl
From the existing doc it is not obvious whether the first or the
second argument is the accumulator. This is however relevant to
know, as for certain scenarios, this might change the behavior.
