39d526bde48d98af4fa27906e85db0399b6aa8b1 test: Bump linter versions (Duncan Dean)
Pull request description:
As per #19346, `mypy==0.700` was incompatible with Python 3.8.
I've bumped the versions of all the linters to their latest stable versions.
Checked with both Python 3.7 and 3.8 and everything still seems to work fine.

b21680baf5391a602b295b9d7d0ef66553661cb9 test/contrib: Fix invalid escapes in regex strings (Ben Woosley)
Pull request description:
This is a second go at #15221, fixing new lints in:
W504 line break after binary operator
W605 invalid escape sequence
F841 local variable 'e' is assigned to but never used
This time around:
* One commit per rule, for easier review
* I went with the PEP-8 style of breaking before binary operators
* I looked into the raw regex newline issue, and found that raw strings with newlines embedded do work appropriately. E.g. run `re.match(r" \n ", " \n ")` to check this for yourself. `re.MULTILINE` exists to modify `^` and `$` in multiline scenarios, but all of these searches are per-line.

3f8776a1391c3978ed66144df15fd9bcb9edd35d Re-add dead code detection (flack)
Pull request description:
This re-adds unreachable code detection for Python based on `vulture`.
Effectively, this reverts f4beb4996d27f2cdaf4f0a63e7dc044bf17decce. 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

f4beb4996d27f2cdaf4f0a63e7dc044bf17decce test: Remove python dead code linter (Wladimir J. van der Laan)
Pull request description:
Primarily I'd like to remove this because it is very imprecise, due to Python's dynamic nature, giving it a large list of false positives that need to be listed as exceptions. See for example #16906.
It's also a frequent source of complaints. I'm doubtful of the usefulness of checking for dead code in a linter in the first place.
Having some dead code in the test framework for a while is not a
disaster.

b748bf6f50dda6bb57eadf697edc320b2695e01a Fix spelling errors identified by codespell 1.15.0 (Ben Woosley)
Pull request description:
Note all changes are to comments / documentation.
After this commit, the only remaining output is:
```
$ test/lint/lint-spelling.sh

^ Warning: codespell identified likely spelling errors. Any false positives? Add them to the list of ignored words in test/lint/lint-spelling.ignore-words.txt
```
Note:
* I ignore several valid alternative spellings ~, but changed homogenous
to homogeneous as the latter is a more specific term according to the
Google dictionary definitions I found~
* homogenous is present in tinyformat, hence should be addressed upstream
* process' is correct only if there are plural processes

c82190cdb6 tests: Add Python dead code linter (vulture) (practicalswift)
590a57fdec tests: Remove unused testing code (practicalswift)
Pull request description:
Add Python dead code linter (`vulture`) to Travis.
Rationale for allowing dead code only after explicit opt-in (via `--ignore-names`):
* Less is more :-)
* Unused code is by definition "untested"
* Unused code can be an indication of bugs/logical errors. By making the contributor aware of newly introduced unused code it gives him/her an opportunity to investigate if the unused code they introduce is malignant or benign :-)
* Unused code is hard to spot for humans and is thus often missed during manual review
* [YAGNI](https://en.wikipedia.org/wiki/You_aren%27t_gonna_need_it)
Based on #14312 to make linter job pass.

Pull request description:
This PR is extracted from https://github.com/bitcoin/bitcoin/pull/13816 to make that one easier to review. It follows on https://github.com/bitcoin/bitcoin/pull/13849 and https://github.com/bitcoin/bitcoin/pull/13851
In here the shell script parts from `travis.yml` are extracted into `.travis/before_install.sh`, `.travis/install.sh`, `.travis/before_script.sh`, `.travis/script.sh`, and `.travis/lint.sh`.
This has the benefit that `test/lint/lint-shell.sh` will also shellcheck these parts. Also it makes the individual script parts more readable.
