Add a `secretKeyFiles` URI parameter in the store URIs receiving a
coma-separated list of Nix signing keyfiles.
For instance:
nix copy --to "file:///tmp/store?secret-keys=/tmp/key1,/tmp/key2" \
"$(nix build --print-out-paths nixpkgs#hello)"
The keys passed through this new store URI parameter are merged with
the key specified in the `secretKeyFile` parameter, if any.
We'd like to rotate the signing key for cache.nixos.org. To simplify
the transition, we'd like to sign the new paths with two keys: the new
one and the current one. With this, the cache can support nix
configurations only trusting the new key and legacy configurations
only trusting the current key.
See https://github.com/NixOS/rfcs/pull/149 for more informations
behind the motivation.

Revert most of "Hack together a fix for the public headers"
- The `libmain` change is kept, and one more libmain change is made.
(Need to update Meson and Nix per the package alike).
- The S3 situation is fixed in a different way: the variable is public
now, used in the header, and fixed accordingly.
- Fix TODO for `HAVE_EMBEDDED_SANDBOX_SHELL`
This reverts commit 2b51250534.
Previously, when lock file contained invalid JSON nix reported a parser
error without specifying the file it came from.
This change adds flake.lock file path to the error message to avoid
confusion.
This is required for other bindings like nix-flake-c to hook into
nix-expr-c appropriately.
The `_internal` part should be a sufficient deterrent normally,
and it may also be useful for bindings that migrate from the C++
interface.
