Support opening local store with database on read-only filesystem (#8356)
Previously it was not possible to open a local store when its database is on a read-only filesystem. Obviously a store on a read-only filesystem cannot be modified, but it would still be useful to be able to query it.

This change adds a new read-only setting to LocalStore. When set to true, Nix will skip operations that fail when the database is on a read-only filesystem (acquiring big-lock, schema migration, etc), and the store database will be opened in immutable mode.

d2696cdd1e Fix build hook error for libstore library users
A library shouldn't require changes to the caller's argument handling,
especially if it doesn't have to, and indeed we don't have to.

This changes the lookup order to prioritize the hardcoded path to nix
if it exists. The static executable still finds itself through /proc
and the like.

d41e1bed5e Experimentally allow forcing nix-daemon trust; use this to test
We finally test the status quo of remote build trust in a number of
ways. We create a new experimental feature on `nix-daemon` to do so.

PR #3921, which improves the situation with trustless remote building,
will build upon these changes. This code / tests was pull out of there
to make this, so everything is easier to review, and in particular we
test before and after so the new behavior in that PR is readily apparent
from the testsuite diff alone.

9207f94582 Add Store::isTrustedClient()
This function returns true or false depending on whether the Nix client
is trusted or not. Mostly relevant when speaking to a remote store with
a daemon.

We include this information in `nix ping store` and `nix doctor`

f9c24d67b9 Add a test with flake.nix in a submodule
I noticed a regression in the lazy-trees branch, which I'm trying to
capture with this test. While the tests succeeds in master, the
lazy-trees branch gives the following error message:

    error: access to path
    '/build/nix-test/tests/flakes/flake-in-submodule/rootRepo/submodule/flake.nix'
    is forbidden because it is not under Git control; maybe you should
    'git add' it to the repository
    '/build/nix-test/tests/flakes/flake-in-submodule/rootRepo'?

c11836126b Harden tests' bash
Use `set -u` and `set -o pipefail` to catch accidental mistakes and
failures more strongly.

 - `set -u` catches the use of undefined variables
 - `set -o pipefail` catches failures (like `set -e`) earlier in the
   pipeline.

This makes the tests a bit more robust. It is nice to read code not
worrying about these spurious success paths (via uncaught) errors
undermining the tests. Indeed, I caught some bugs doing this.

There are a few tests where we run a command that should fail, and then
search its output to make sure the failure message is one that we
expect. Before, since the `grep` was the last command in the pipeline
the exit code of those failing programs was silently ignored. Now with
`set -o pipefail` it won't be, and we have to do something so the
expected failure doesn't accidentally fail the test.

To do that we use `expect` and a new `expectStderr` to check for the
exact failing exit code. See the comments on each for why.

`grep -q` is replaced with `grepQuiet`, see the comments on that
function for why.

`grep -v` when we just want the exit code is replaced with `grepInverse,
see the comments on that function for why.

`grep -q -v` together is, surprise surprise, replaced with
`grepQuietInverse`, which is both combined.

87da941348 Clean up daemon handling
Split `common.sh` into the vars and functions definitions vs starting
the daemon (and possibly other initialization logic). This way,
`init.sh` can just `source` the former. Trying to start the daemon
before `nix.conf` is written will fail because `nix daemon` requires
`--experimental-features 'nix-command'`.

`killDaemon` is idempotent, so it's safe to call when no daemon is
running.

`startDaemon` and `killDaemon` use the PID (which is now exported to
subshells) to decide whether there is work to be done, rather than
`NIX_REMOTE`, which might conceivably be set differently even if a
daemon is running.

`startDaemon` and `killDaemon` can save/restore the old `NIX_REMOTE` as
`NIX_REMOTE_OLD`.

`init.sh` kills daemon before deleting everything (including the daemon
socket).

5dbbf23332 Make init.sh safe to run twice
`init.sh` is tested on its own. We used to do that. I deleted it in
4720853129 but I am not sure why. Better
to just restore it; at one point working on this every other test
passed, so seems good to check whether `init.sh` can be run twice.

We don't *need* to run `init.sh` twice, but I want to try to make our
tests as robust as possible so that manual debugging (where tests for
better or worse might be run ways that we didn't expect) is less
fragile.

55016b6fcd Test nix build --json return output paths in floating CA case
Adding a test to ensure there is no regression.

The tests that are split out of `tests/build.sh` are ones that don't yet
work with CA derivation. I have not yet evaluated whether they should or
not.

This behavior, reported missing in issue #4661, already got fixed in
PR #4818, but didn't get a test case then.

0251d44cc2 Make ./mk/run-test.sh work by itself; add mk/debug-test.sh
First, logic is consolidated in the shell script instead of being spread
between them and makefiles. That makes understanding what is going on a
little easier.

This would not be super interesting by itself, but it gives us a way to
debug tests more easily. *That* in turn I hope is much more compelling.
See the updated manual for details.

5c97b5a398 InstallableFlake::toDerivedPaths(): Support paths and store paths
This makes 'nix build' work on paths (which will be copied to the
store) and store paths (returned as is). E.g. the following flake
output attributes can be built using 'nix build .#foo':

  foo = ./src;
  foo = self.outPath;
  foo = builtins.fetchTarball { ... };
  foo = (builtins.fetchTree { .. }).outPath;
  foo = builtins.fetchTree { .. } + "/README.md";
  foo = builtins.storePath /nix/store/...;

Note that this is potentially risky, e.g.

  foo = /.;

will cause Nix to try to copy the entire file system to the store.

What doesn't work yet:

  foo = self;
  foo = builtins.fetchTree { .. };

because we don't handle attrsets with an outPath attribute in it yet,
and

  foo = builtins.storePath /nix/store/.../README.md;

since result symlinks have to point to a store path currently (rather
than a file inside a store path).

Fixes #7417.
