We were using an outdated CBOR crate for MSRV reasons. But this old
crate is causing suprious test failures. So delete it. (Sadly, updating
the crate doesn't fix the issue, replacing it with ciborium breaks our
MSRV tests because it needs a more recent `half` dependency, and
replacing it with `minicbor` doesn't work because minicbor is not based
on serde. So we don't really have any options.)
In general, I am suspicious of this decode-then-reencode test. CBOR has
some ambiguity in integer encoding. Empirically it has seemed to
work for a long time, but this seems more like an indictment of our test
than a positive result.
Also, round-trip testing serde encoding of a byte vector is probably not
a great use of our fuzz resources. I don't believe we have ever had a
problem with this.
Fixes#2801
Recently we modified the fuzz job manually and forgot about the
`generate-files.sh` file.
Update the script to match the current CI job, running it now produces
the same file `cron-daily-fuzz.sh`.
Add `euo pipefail` to all non-trial shell scripts, note if `x` is
already set we maintain it.
Note we have a pipe in `run_task.sh` that relies on grep not finding
anything i.e., failing, so we cannot use pipefail there. Disable it and
re-enable it after the pipe.

fix
ci(fuzz): change runner to ubuntu-latest
ci: update run syntax in fuzz job
ci: update and run fuzz/generate-files.sh
We should probably restore this in the future, but we need to rethink
how we fuzz hashes -- right now when cfg(fuzzing) is set, we break all
the hash functions in a way that won't match any other library.
We should probably make this breakage opt-in but this will require
buy-in from rust-lightning and maybe others.
AFAICT we literally never used this; it was available only on the
bitcoin targets and not the honggfuzz ones; AFL has a broken dep
tree (or at least, requires some more MSRV pins that I did not care
to investigate).
Just remove it entirely.
