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).

f0579313d3 fix(users/Profpatsch/read-http): actually parse ascii
There might be exploits since we parsed the headers as utf8 even
though we actually want to interpret them as ASCII.

This fixes it, by using the ascii crate.

Thanks to @sterni for noticing.

3877243211 feat(users/Profpatsch/netencode): add decoder module
Decoders are implemented not directly on output types, but on trivial
proxy types, so that we can easily combine those into a decoder, and
then the associated type is the actual return value of the decoder.

2f807d7f14 feat(users/Profpatsch): add a rewriter for lib.stdenv changes
This is in order to advance the rewriting from stdenv.lib to lib.
https://github.com/NixOS/nixpkgs/issues/108938

The hard part about changing the argument is that a package might not
include lib in its arguments, which is why I use hnix to check whether
lib is included and add it to the import list if it doesn’t already
exist there.

So far, only the really common pattern of

    meta = with stdenv.lib;

is rewritten.
