Noticed in https://github.com/NixOS/nixpkgs/pull/269439
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.

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.

https://github.com/NixOS/nixpkgs/pull/269064 makes rapidcheck be build
as a shared lib, but that broke Nix because the `-lrapidcheck` was
missing. This fixes that (and doesn't break Nix what the library is a
static archive as today).
It is not inherently tied to `LocalStore`, it could probably even go in
`libnixutil`. Functions not attached to `LocalStore` should not be
declared in `local-store.hh`.
I am moving it to facilitate experimenting for #9344. If
canonicalisation should be done client-side in client-side builds, there
wouldn't be a `LocalStore` at all so having to include that header to
get this freestanding function is cumbersome and wrong.
Perhaps canonicalisation should still be done server-side for security
reasons --- I don't mean to make that judgement call now --- but even if
so, this freestanding function still isn't connected to `LocalStore` so
while less urgent it is still better to move out of this header.
This avoids repeated copying of the same source tree between Nix
invocations. It requires the accessor to have a "fingerprint" (e.g. a
Git revision) that uniquely determines its contents.
