libstore/daemon.cc: note trust model difference in readDerivation()s

Adam Joseph e43bb655fe libstore/daemon.cc: note trust model difference in readDerivation()s
Below the comment added by this commit is a much longer comment
followed by a trust check, both of which have confused me on at
least two occasions.  I figured it out once, forgot it, then had to
ask @Ericson2314 to explain it, at which point I understood it
again.  I think this might confuse other people too, or maybe I will
just forget it a third time.  So let's add a comment.

Farther down in the function is the following check:

```
if (!(drvType.isCA() || trusted))
  throw Error("you are not privileged to build input-addressed derivations");
```

This seems really strange at first.  A key property of Nix is that
you can compute the outpath of a derivation using the derivation
(and its references-closure) without trusting anybody!

The missing insight is that at this point in the code the builder
doesn't necessarily have the references-closure of the derivation
being built, and therefore needs to trust that the derivation's
outPath is honest.  It's incredibly easy to overlook this, because
the only difference between these two cases is which of these
identically-named functions we used:

- `readDerivation(Source,Store)`
- `Store::readDerivation()`

These functions have different trust models (except in the special
case where the first function is used on the local store).  We
should call the reader's attention to this fact.

John Ericson deadb3bfe9 Create header for LegacySSHStore
In https://github.com/NixOS/nix/pull/6134#issuecomment-1079199888,
@thuffschmitt proposed exposing `LegacySSHStore` in Nix for
deduplication with Hydra, at least temporarily. I think that is a good
idea.

Note that the diff will look bad unless one ignores whitespace! Also try
this locally:

```shell-session
git diff --ignore-all-space HEAD^:src/libstore/legacy-ssh-store.cc HEAD:src/libstore/legacy-ssh-store.cc
git diff --ignore-all-space HEAD^:src/libstore/legacy-ssh-store.cc HEAD:src/libstore/legacy-ssh-store.hh

document fetchTree (#9258)
* document `fetchTree`

* display experimental feature note at the top

we have to enable the new `fetchTree` experimental feature to render it
at all. this was a bug introduced when adding that new feature flag.

John Ericson f9ee1bedcf Avoid std::strstream, fix the clang build
According https://en.cppreference.com/w/cpp/io/strstream, it has been
deprecated since C++98! The Clang + Linux build systems to not have it
at all, or at least be hiding it.

We can just use `std::stringstream` instead, I think.

Print the value in error: cannot coerce messages (#9553)
* Print the value in `error: cannot coerce` messages

This extends the `error: cannot coerce a TYPE to a string` message
to print the value that could not be coerced. This helps with debugging
by making it easier to track down where the value is being produced
from, especially in errors with deep or unhelpful stack traces.

John Ericson 96dd757b0c Give Derivation::tryResolve an evalStore argument
This is needed for building CA deriations with a src store / dest store
split. In particular it is needed for Hydra.

https://github.com/NixOS/hydra/issues/838 currently puts realizations,
and thus build outputs, in the local store, but it should not.

Pass positions when evaluating
This includes position information in more places, making debugging
easier.

Before:

```
$ nix-instantiate --show-trace --eval tests/functional/lang/eval-fail-using-set-as-attr-name.nix
error:
       … while evaluating an attribute name

         at «none»:0: (source not available)

       error: value is a set while a string was expected
```

After:

```
error:
       … while evaluating an attribute name

         at /pwd/lang/eval-fail-using-set-as-attr-name.nix:5:10:

            4| in
            5|   attr.${key}

John Ericson a5521b7d94 Factor out ServeProto::Serialiser<UnkeyedValidPathInfo> and test
In the process, partially undo e89b5bd0bf
in that the ancient < 2.4 version is now supported again by the
serializer again. `LegacySSHStore`, instead of also asserting that the
version is at least 4, just checks that `narHash` is set.

This allows us to better test the serializer in isolation for both
versions (< 4 and >= 4).

Merge pull request #9557 from bryanhonof/bryanhonof.fix-apple-double-shenanigans
Add option to libarchive so it behaves correctly

Bryan Honof bf00d5ecef
fix(libutil/tarfile): add option to libarchive so it behaves correctly with AppleDouble files
AppleDouble files were extracted differently on macOS machines than on other
UNIX's.
Setting `archive_read_set_format_option(this->archive, NULL ,"mac-ext",NULL)`
fixes this problem, since it just ignores the AppleDouble file and treats it as
a normal one.
This was a problem since it caused source archives to be different between macOS
and Linux.
