dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 refactor: test: use _ variable for unused loop counters (Sebastian Falbesoner)
Pull request description:
This tiny PR substitutes Python loops in the form of `for x in range(N): ...` by `for _ in range(N): ...` where applicable. The idea is indicating to the reader that a block (or statement, in list comprehensions) is just repeated N times, and that the loop counter is not used in the body, hence using the throwaway variable. This is already done quite often in the current tests (see e.g. `$ git grep "for _ in range("`). Another alternative would be using `itertools.repeat` (according to Python core developer Raymond Hettinger it's [even faster](https://twitter.com/raymondh/status/1144527183341375488)), but that doesn't seem to be widespread in use and I'm not sure about a readability increase.
The only drawback I see is that whenever one wants to debug loop iterations, one would need to introduce a loop variable again. Reviewing this is basically a no-brainer, since tests would fail immediately if a a substitution has taken place on a loop where the variable is used.
Instances to replace were found by `$ git grep "for.*in range("` and manually checked.

ACK dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 -- the updated code is easier to reason about since the throwaway nature of a variable is expressed explicitly (using the Pythonic `_` idiom) instead of implicitly. Explicit is better than implicit was we all know by now :)

98892f39e3d079c73bff7f2a5d5420fa95270497 doc: Improve setup_clean_chain documentation (Fabian Jahr)
Pull request description:
The first commit improves documentation on setup_clean_chain which is misunderstood quite frequently. Most importantly it fixes the TestShell docs which are simply incorrect.
The second commit removes the instances of `setup_clean_clain` in functional tests where it is not changing the default.
This used to be part of #19168 which also sought to rename`setup_clean_chain`.

Pull request description:
Follow up to #16257, this PR makes `bumpfee` aware of `-maxtxfee`.
It also prevents dangling locked unspents when calling `fundrawtransaction` - because the previous check was after `LockCoin`.
