8707773965 Properly lock the builds of CA derivations
Make sure that we can’t build the same derivation twice at the same
time.

a4ec6cb1da Be more lenient when realisations have a conflicting dependency set
- This can legitimately happen (for example because of a non-determinism
  causing a build-time dependency to be kept or not as a runtime
  reference)
- Because of older Nix versions, it can happen that we encounter a
  realisation with an (erroneously) empty set of dependencies, in which
  case we don’t want to fail, but just warn the user and try to fix it.

9b1f3cbc13 Forward the whole Nix config to the post-build-hook
Fill `NIX_CONFIG` with the value of the current Nix configuration before
calling the post-build-hook.
That way the whole configuration (including the possible
`experimental-features`, a possibly `--store` option or whatever) will
be made available to the hook

7bc17a903b fixed output derivations: fix incorrect responses for getpwuid
Passing nscd socket into the build environment causes unexpected behavior in programs that make getpwuid and other related calls.

2cf14db857 Throw on unexpected input for --delete-older-than
'--delete-older-than 10' deletes the generations older than a single day, and '--delete-older-than 12m' deletes all generations older than 12 days.

This changes makes it throw on those invalid inputs, and gives an example of a valid input.

7746cb13dc Make CA derivations compatible with recursive Nix
Add an access-control list to the realisations in recursive-nix (similar
to the already existing one for store paths), so that we can build
content-addressed derivations in the restricted store.

Apply OS checks to host platform, not build
Previously, the build system used uname(1) output when it wanted to
check the operating system it was being built for, which meant that it
didn't take into-account cross-compilation when the build and host
operating systems were different.

To fix this, instead of consulting uname output, we consult the host
triple, specifically the third "kernel" part.

For "kernel"s with stable ABIs, like Linux or Cygwin, we can use a
simple ifeq to test whether we're compiling for that system, but for
other platforms, like Darwin, FreeBSD, or Solaris, we have to use a
more complicated check to take into account the version numbers at the
end of the "kernel"s.  I couldn't find a way to just strip these
version numbers in GNU Make without shelling out, which would be even
more ugly IMO.  Because these checks differ between kernels, and the
patsubst ones are quite fiddly, I've added variables for each host OS
we might want to check to make them easier to reuse.

Set environment variables for .attrs.json & .attrs.sh
This way no derivation has to expect that these files are in the `cwd`
during the build. This is problematic for `nix-shell` where these files
would have to be inserted into the nix-shell's `cwd` which can become
problematic with e.g. recursive `nix-shell`.

To remain backwards-compatible, the location inside the build sandbox
will be kept, however using these files directly should be deprecated
from now on.

Source complete env in nix-shell with __structuredAttrs = true;
This is needed to push the adoption of structured attrs[1] forward. It's
now checked if a `__json` exists in the environment-map of the derivation
to be openend in a `nix-shell`.

Derivations with structured attributes enabled also make use of a file
named `.attrs.json` containing every environment variable represented as
JSON which is useful for e.g. `exportReferencesGraph`[2]. To
provide an environment similar to the build sandbox, `nix-shell` now
adds a `.attrs.json` to `cwd` (which is mostly equal to the one in the
build sandbox) and removes it using an exit hook when closing the shell.

To avoid leaking internals of the build-process to the `nix-shell`, the
entire logic to generate JSON and shell code for structured attrs was
moved into the `ParsedDerivation` class.

4202a3bc4e UDSRemoteStore: Support the 'root' store parameter
Useful when we're using a daemon with a chroot store, e.g.

  $ NIX_DAEMON_SOCKET_PATH=/tmp/chroot/nix/var/nix/daemon-socket/socket nix-daemon --store /tmp/chroot

Then the client can now connect with

  $ nix build --store unix:///tmp/chroot/nix/var/nix/daemon-socket/socket?root=/tmp/chroot nixpkgs#hello

5985b8b527 Check the CA hash when importing stuff in the local store
When adding a path to the local store (via `LocalStore::addToStore`),
ensure that the `ca` field of the provided `ValidPathInfo` does indeed
correspond to the content of the path.
Otherwise any untrusted user (or any binary cache) can add arbitrary
content-addressed paths to the store (as content-addressed paths don’t
need a signature).
