This is because there is a small possibility that the `nix repl` child
process hasn't created `repl_output` yet. So make sure it exists.

error:
… while processing sandbox path '/private/tmp/nix-shell.0MDgyx/nix-test/ca/repl/store/nix/var/nix/builds/nix-build-simple.drv-65916-3910734210' (/private/tmp/nix-shell.0MDgyx/nix-test/ca/repl/store)
error: 'nix' is too short to be a valid store path
which happened because we were now putting the build directory
underneath the store directory.
If a build directory is accessible to other users it is possible to
smuggle data in and out of build directories. Usually this is only
a build purity problem, but in combination with other issues it can
be used to break out of a build sandbox. to prevent this we default
to using a subdirectory of nixStateDir (which is more restrictive).

(store setting done by roberth)
We can always compute the store path from the content hash, but not
vice versa. Storing the content hash allows `hashPath()` to be
replaced by `fetchToStore(...FetchMode::DryRun...)`, which gets us
caching in lazy-trees mode.
libstdc++'s std::stable_sort and new builtins.sort implementation
special-case ranges with length less than or equal to 16 and delegate
to insertionsort.
Having a larger e2e test would allow catching sort stability issues
at functional level as well.
Makes the behavoral change of #13263 without the underlying refactor.
Hopefully this clearly safe from a perf and GC perspective, and will
make it easier to benchmark #13263.
This adds a meson.format file that mostly mirrors the projects
meson style and a pre-commit hook to enforce this style.
Some low-diff files are formatted.
