Merge #21096: Re-add dead code detection 
3f8776a139 Re-add dead code detection (flack)

Pull request description:

  This re-adds unreachable code detection for Python based on `vulture`.

  Effectively, this reverts f4beb4996d. The difference to the previous version is that this runs with the `--min-confidence 100` setting. From https://pypi.org/project/vulture/:

  > Use `--min-confidence 100` to only report code that is guaranteed to be unused within the analyzed files.

  So this should avoid the previous issues where static analysis had wrong positives due to the dynamic nature of Python code by only reporting things that are unambiguous (such as code after a `return` statement). As such, there is not suppressions list.

  My motivation was mainly #21081 which would have been caught by this (as can be seen by the CI run failing). This is still marked as draft because #21081 is needed to get the linter to pass. Also, there is a second problem that this found (see https://github.com/bitcoin/bitcoin/pull/19509/files#r571454691). From what I can tell, this is a spurious type comment that could just be removed (or if that line has no side effects it could also be deleted altogether?). I could add a commit here to fix it, but I wanted to see if there is interest in having this linter again in the first place

README.md

This folder contains lint scripts.

check-doc.py

Check for missing documentation of command line options.

commit-script-check.sh

Verification of scripted diffs. Scripted diffs are only assumed to run on the latest LTS release of Ubuntu. Running them on other operating systems might require installing GNU tools, such as GNU sed.

git-subtree-check.sh

Run this script from the root of the repository to verify that a subtree matches the contents of the commit it claims to have been updated to.

Usage: test/lint/git-subtree-check.sh [-r] DIR [COMMIT]
       test/lint/git-subtree-check.sh -?
  • DIR is the prefix within the repository to check.
  • COMMIT is the commit to check, if it is not provided, HEAD will be used.
  • -r checks that subtree commit is present in repository.

To do a full check with -r, make sure that you have fetched the upstream repository branch in which the subtree is maintained:

To do so, add the upstream repository as remote:

git remote add --fetch secp256k1 https://github.com/bitcoin-core/secp256k1.git

lint-all.sh

Calls other scripts with the lint- prefix.
