fed41f4959 feat(users/Profpatsch): set up stow for nix-home
nix-home is (hopefully) gonna be a home-manager alternative for my
home directory.

Files are symlinked into the home directory via GNU stow (since that
is a tried and tested tool), so first step is to set up the base code
for that.

Implements a small tool that reads a single environment variable and
prints it to stdout.

4f1249e46f refactor(readTree): Move 'drvTargets' into readTree
This function is also generally useful for readTree consumers that
have the concept of subtargets.

eb41eef612 chore(nix): move rustSimple from users.Profpatsch.writers
I think it’s solid enough to use in a wider context.

5d8490d2fc feat(users/Profpatsch): build attrset members on CI
Setting meta.targets to include all derivations in the different package
sets in Profpatsch's user folder makes them checked by CI until they do
the readTree refactor as promised.

To reduce code duplication we handle this in a simple function which is
exposed from nix.utils which may be a good place for depot specific bits
and bops we accumulate over time.

To get around the issue of too nested sets we perform the following
renames:

* users.Profpatsch.tests gets moved into its own directory
* users.Profpatsch.arglib.netencode now lives in its own file instead of
  the default.nix
* users.Profpatsch.netstring.tests gets moved into its own directory

81122c1297 feat(users/Profpatsch/execline/exec_helpers): add args()
Some programs need an exact amount of arguments, and we want to fail
if they get too many or not enough.

060600f0d7 feat(users/Profpatsch/execline/exec_helpers): add no_args()
Some programs don’t need any arguments, so fail if they do get them,
because that’s usually a bug.

7d28f121c7 fix(users/Profpatsch/execline): fix exec_into_args off-by-1
We expect the users to pass an actual prog, not an argv, so 0 is the
program to exec into.

Also improve the exec error, by including the program we tried to exec
into (the rust IO error doesn’t contain the name).

492b79ec7a feat(users/Profpatsch): add die_* helpers for semantic exit errors
There is this semantic exit code schema championed by execline and
skaware tooling, and we refined and documented it a bit in lorri
d1d673d420/src/ops/mod.rs (L24-L35)
in the past.

This just transcribes the error messages into simple helper functions.

Applies the functions to the places where we would panic or die
`sys::exit()` instead.

83634341aa feat(users/Profpatsch/execline): add args_for_exec
`exec_into_args` would just read argv and exec into it, but we want to
be able to write commands which take some positional arguments first.

Thus we split the invocation into `args_for_exec`, which returns the
positional arguments and prog, and then pass prog to `exec_into_args`
when we want to exec eventually (prog is still an iterator at this
point).

Most tools end by execing into their argv, so here’s a small rust
function which does the boilerplate.
