Call it a bug, call it a feature, but the old testing framework
ungracefully shits itself when it has no tests to run … in other words,
we finally migrated all the parse-fail tests 🎉

The second test has also been fixed. I'd do it in two commits if
functional1 wasn't such a PITA (guess why we're doing the migration …).
Basically, the introduced syntax got changed later on, but the test
never got updated, and back then tests didn't test the output so nobody
ever noticed it now failing for a wrong reason.

This really looks like one of the first tests ever written, it doesn't
seem to be actively testing anything interesting

Channels have moved from `nixos.org/channels` to `cnannels.nixos.org`.
This udates all relevant links (excluding release notes) to use the new
canonical URLs and replaces HTTP with HTTPS.
Fixes#1031.

This is unnecessary because Darwin builds already cannot create
`set{u,g}id` files due to the minimal sandbox policy, because we can
forbid messing with the top‐level build directory directly in the
sandbox rules, and because Darwin builds can trivially avoid isolation
through temporary directories right now anyway.
This does regress the build directory isolation for builds with
`sandbox = false`, but I can’t imagine that mattering given the
above. The sandbox change prepares us for a world where we close
off shared temporary directories for `sandbox = true` builds and try
harder to achieve proper isolation on Darwin, but probably doesn’t
have a meaningful security impact one way or another for now.
With this change, we get down to 41 byte build directory paths on
Darwin, a ~2–3½ byte improvement over the old status quo. We can
also restore the 0710 permissions on Linux.

the change to shareable thunks also removed a few cases of pointer
equality checks that allowed structures containing functions to be
considered equal to other sets containing the same functions, even
if the sets themselves were pointer-equal themselves. *so* busted.

The test would fail if the identity cannot be determined
(as is the case e.g. when using auto-allocate-uids under darwin).
Instead we use the uid when the user name is not available.

So far it was impossible to put absolute paths into files, as one
wouldn't know whre the test would be placed.
This commit adds a new Fileish variant called `EnvTemplate` which uses
the given string as a template and replaces the `@ENV_VARIABLE_NAME@`
placeholders with the according value of the environment variable.
This way one can use `@HOME@` or `@TEST_ROOT@` to build absolute paths

Calling `nix.nix` with an empty argument list, would crash on darwin due
to a Index Out Of Range Error, as the build="auto" functionallity would
try to access the first element of the provided arguments (second
element at the place of call) resulting in a crash

libarchive's xz offers single threaded xz compression which is very slow
and provides ~10-20Mbps compression speed in addition to maxing a core.
In exchange, it achieves optimal compression ratios among all our
compression methods.
Nonetheless, xz prevent the saturation of 1Gbps+ connections and slow
down significantly decompression for end users. As these connections and
faster hardware is becoming prevalent for cache servers and clients, we
offer to default to zstd.
Lix is a "compress once, decompress many times" application. To avoid
incurring a high penalty to end users very sensitive to compress ratio
(very slow Internet connections), we dampen the consequences of
switching to zstd by increasing the default zstd level to 12.
On one example, xz will compress a 4.4GB file to 632MB, zstd on 12 will
compress it to 775MB, that is a ~18 % increase over the optimal xz
compression. zstd took 18 seconds to produce this file.
Increasing to level 14 leads to a 773MB file while taking 37s.
Increasing to level 16 leads to 735MB file while taking 66s.
Finally, xz took 77s, so a 50 % reduction in time taken to compress in
exchange of an increase of 18 % of the compressed size.
This change will reduce issues encountered in #945 but is probably not
the root cause.

Instead of letting inner shell perform the cleanup, we will fork/execvp
and finish the work ourselves. Once an interruption arrives, we wait
again and return the exit status code of the inner shell.
This idea was suggested by eldritch horrors.
Fixes#1020.

the wrapper is needed by transfer streams to restart a failed transfer
if desired. curlFileTransfer itself is more of a fancy handler for the
thread we're dedicating to curl io handling. the thread will stay with
the multi handle for now because quit handling needs to stay there. we
could have CurlMulti keep only a flag, but that does not help us much.
