The coerce integer feature was not rebased before merge and we do not
have a merge queue, hence, after merge, the HEAD was in a broken state.
We take a commitment to invest into a merge queue now and do a fixup
here.

When assigning an a value to NIX_GET_COMPLETIONS that could not be
parsed as an integer lix would just crash, as the value was directly
passed to stoi, without handling the return value.
This change switches the parsing to use string2Int and throws an
exception if the return value is empty.
The behaviour of lix is slightly changed through, as the value of the
variable was previously parsed to an int and then assigned to a variable
of size_t.
This change in behaviour can only be observed in cases where the
value of NIX_GET_COMPLETIONS is chosen so when it overflows it would
be valid index of the provided arguments again.
Through this change the variable is parsed as a size_t and negative
values are rejected.

When using completion, the number of the word for which the shell
requests completion is provided in the environment variable
`NIX_GET_COMPLETIONS`. When the number smaller than 1 is or larger
than the number of arguments nix coredumps as a assert is violated.
This change removes the assert and instead throws an exception informing
the user that their autocomplete is most likely misconfigured.

This introduces a new (demanded?) feature for coercing integers in
interpolation arguments under the experimental feature
`coerce-integers`.
This feature is being introduced behind an *experimental feature flag*
due to the cautious approach we're taking. The codebase has a track
record of revealing unexpected behaviors, often in subtle ways, so we
want to give this sufficient time and exposure before making it stable.
To remove the experimental flag, we want to see **at least two releases
or six months of real-world usage -- whichever is longer** -- that
demonstrate strong confidence the feature doesn't introduce regressions
or unintended side effects. If that level of confidence is reached,
we'll proceed to stabilize it.

To print completions lix created a Finally object containing the actual function,
so the function was executed by the destructor of the class.
Unfortunately aborting autocomplete by sending a SIGINT signal
(i.E. by pressing C-c) leads to an exception, that finally cant return or eat,
when throwing its own exception.
To avoid crashing when using auto complete let the function "mainWrapped" execute
the autocomplete code directly before returning.
This avoids creating the "Finally" object and instead moves the codeblock next to
the check to return when "arg.completions" is called.

When calling completion on a nix command containing the word
"--help" nix would first return the entire help page for the
command and then the result of the completion resulting in unusable
output.
By moving the check whether to return when completions were requested
before the check whether help was requested wrappedMain returns
without wrongly printing documentation.

with_env now overrides the environment, similar to with_stdin
an additional function update_env was created to mirror the prior
functionality of with_env, updating the env
This was changed as previously it was impossible to delete variables
from the env
replaced the code of .ok() with a call to .expect, to remove the code
duplication

Currently the Command and CommandResult classes are mixed into the nix
fixture file.
This commit moves them out into their own lib file, to make it more
obvious that they can be used standalone for other applications too
Additionally improved documentation of said classes
and bumped log level of stdout and err on unexpected exitcodes, as it is
within an error context

Each `inputFromAttrs` is roughly the same function in each class, we
check that the attributes given are correct (in term of keys and other
types) then we coppy the attributes. Instead of having the same code
copied in 10 places, set it in the parent class and specify what is
specific per child class.

Due to nix-store making its paths read-only, pytest was unable to remove
the test files and hence the entire temporary directory, screaming all
over the place in stderr about that, getting worse for each test run.
By making the nix fixture first yield nix and then, after the test
finished running, changing the file permissions to include read on all
files and directories within the temp folder, pytest is able to properly
remove old test runs again
Additionally added more clear instructions for file deletion to the
pytest configuration

It was introduced back in 2013, was disabled in 2014 again for dubious
reasons and according to horrors is unsound anyways and can never really
work.
It was the only disabled test, so I removed the "infrastructure" for
that in the test runner as well. functional2/lang will have much better
ways for skipping tests anyways

Back in the days, this used to be the modus operandi, but then, still
many but less years ago, Eelco came along and changed it to passing in
the actual file. Of course, no motivation was provided, and it was only
done on half of the test runners for some reason, leaving us to wonder
what the true intentions of this code are …
Anyways, with this commit now everything standardises on passing in the
file by path instead of via stdin. Motivation:
- We need to `sed` out the path anyways for various other reasons,
including import tests and path value tests
- Given that, the presumed primary motivation for using stdin in the
first place becomes moot
- Bonus points for giving better error messages, especially in tests
that involve multiple input files

Don't ask me the fuck why, but *somehow* Nix prints error locations
differently if the input file is passed as a path vs through stdin, and
I have a hunch that this might have to do with tabs

Currently, all tests are relative to `./tests/functional` instead of
`./tests/functional/lang`. Whether this is a historical artefact or as
intended, the current move is to align the tests with the new design of
functional2, preparing them for an easier migration.

we don't need to worry about leaving around old ca data in the database:
this was always a possiblity when enabling ca derivations, and disabling
them again some time later. behavior is unchanged, but we lose dead code

we no longer need placeholders to represent all derivation output paths
as string context, and thus will not need experimental features either.

derivation outpaths are now statically known at all times. the one snag
here is that the wires encode even statically known paths as optionals,
forcing us to check for this any time we receive an output map. remotes
answering with nullopt paths for derivations we still support now would
be a protocol error on its own though, so we do not diagnose it deeply.

we don't need to touch the schema of the cache here. keeping the table
around doesn't hurt (and avoids cppnix breakage) thanks to foreign key
constraints and the ca bits of the schema being independent enough for
us to just ignore them (and not having to do any maintenance on them).

only a daemon wire operation and the perl bindings could initiate these
queries at this point. the daemon ops can throw an error instead (as if
the daemon were older) and realistically should never be queries if the
client hasn't evaluated a ca derivation on a given store, and perl code
is best off dying early. nothing known except hydra uses these bdingins
anyway, and we control our hydra so we don't need backward compat code.

it's only used by the RegisterDrvOutput daemon wire operation now, and

importantly, realisation closure copy support. the latter is not

now that we have no deferred hashes (since floating ca derivations were
the only way to create them) we can safely remove this enumeration too.
