86dbd54ae8a8f9c693c0ea67114bbff24a0754df test: improve mempool_updatefrom efficiency by using getmempoolentry for specific txns (Michael Dietz)
Pull request description:
I don't think this changes the intention of the test. But it does shave ~30 seconds off the time it takes to run. From what I've seen our CI `macOS 11 native [gui] [no depends]` runs `mempool_updatefrom.py` in ~135 seconds. After this PR it should run in ~105 seconds
I noticed this improvement should probably be made when testing performance/runtimes of https://github.com/bitcoin/bitcoin/pull/22698. But I wanted to separate this out from that PR so the affects of each is decoupled
Edit: The major change in this PR is improving mempool_updatefrom.py's runtime as this is a very long running test. Then made the same efficiency improvements across all the functional tests as it made since to do that here

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 :)

8098dea06944f9de8b285f44958eb98761f133ee test: Add mempool_updatefromblock.py (Hennadii Stepanov)
Pull request description:
This PR adds a new test for mempool update of transaction descendants/ancestors information (count, size) when transactions have been re-added from a disconnected block to the mempool.
It could be helpful for working on PRs like #17925, #18191.
