OpenBSD doesn't support `lutimes`, but does support `utimensat` which
subsumes it. In fact, all the BSDs, Linux, and newer macOS all support
it. So lets make this our first choice for the implementation.
In addition, let's get rid of the `lutimes` `ENOSYS` special case. The
Linux manpage says

which I think is the origin of this check, but that's a very old version
of Linux at this point. The code can be simplified a lot of we drop
support for it here (as we've done elsewhere, anyways).

Nix fails to build on OpenBSD with a linking error due to a non-found
symbol in boehm-gc. Just disable the GC until we can find a proper
workaround.

OpenBSD dynamic libraries never link to libc directly.
Instead, they have undefined symbols for all libc functions they use
that ld.so resolves to the libc referred to in the main executable.
Thus, disallowing undefined symbols will always fail

Backward-compatible schema changes (e.g. those that add tables or
nullable columns) now no longer need a change to the global schema
file (/nix/var/nix/db/schema). Thus, old Nix versions can continue to
access the database.
This is especially useful for schema changes required by experimental
features. In particular, it replaces the ad-hoc handling of the schema
changes for CA derivations (i.e. the file /nix/var/nix/db/ca-schema).
Schema versions 8 and 10 could have been handled by this mechanism in
a backward-compatible way as well.

the default int64_t max was still overflowing for me, when this was dumped as json (noticed during building the manual).
So making 0, the default and define it as "no warnings" fixes the situtation.
Also it's much more human-readable in documentation.
This works because the `builder` and `args` variables are only used
in the non-builtin code path.

tests/functional/help.sh calls nix-* commands with option --help
if nix is built without documentation the option --help throws an error
because the man page it wants to display is missing
This overall seems like insecure tmp file handling to me. Because other
users could replace files in /tmp with a symlink and make the nix-shell
override other files.
