Delete nonreduced inputs

[maflcko]

As per the usual process to avoid wasted CI resources and timeouts when it runs on large and presumed irrelevant inputs.

Previous: #119

To "reproduce"

Install a fresh VM, as explained in the bash script's doc, and run it:

apt update && apt install curl -y
curl -L -O https://raw.githubusercontent.com/bitcoin-core/bitcoin-maintainer-tools/main/delete_nonreduced_fuzz_inputs.sh
bash delete_nonreduced_fuzz_inputs.sh

To "test"

• Keep an eye on coverage stats, to ensure it doesn't drop
• Re-run the script, to ensure it is "reproducible" to some extent
• Anything else you think is important to test or review

Did a second run. Some stats:

• 400k deleted files (this pull):

# git diff --stat origin/main..01a9287310b6c2e6344e28c4ba655d179142f719 | tail -1
 446405 files changed, 5974234 deletions(-)

• Same on the second run:

# git diff --stat origin/main..HEAD | tail -1
 444894 files changed, 5404772 deletions(-)

• Cross-diff of 24k files:

# git diff --stat 01a9287310b6c2e6344e28c4ba655d179142f719..HEAD | tail -1

lint fail is expected (obviously)

Looks like utxo_total_supply is the reason for the 2h timeout. I've removed the large fuzz inputs in this folder for now.

Looks like the CI passed after 43minutes now: https://cirrus-ci.com/task/4832424811560960?logs=ci#L4022

Looks like utxo_total_supply is the reason for the 2h timeout. I've removed the large fuzz inputs in this folder for now.

We could add options for that target either to oss-fuzz or in the target itself (e.g. if (buffer.size() > N) return;) to avoid large inputs in the future.

[maflcko]

Let's create a separate tracking issue for this target?
