0a1b6fa test: fix intermittent timeouts in p2p_timeouts.py (Martin Zumsande)

Pull request description:

  Fixes  bitcoin#23800 by making sure that all peers are connected (i.e. `m_connected` is set) before the mocktime is bumped.
  We can't wait for verack here, but we can wait for a debug log entry ("Added connection peer=2") instead.

  In the failed CI runs (e.g. https://cirrus-ci.com/task/5600553806856192?logs=ci#L7469)  different peers were added at different mocktimes.

86a4a15 Highlight DNS request part (Prayank)

Pull request description:

  _What?_

  Highlight DNS requests part in Proxy section

  _Why?_

  1. DNS requests are very important while considering privacy
  2. Lot of users might skip reading it because of the way it is mixed with everything else in the doc right now
  3. I have seen lot of users ignoring DNS requests or unaware of such things while using privacy tools

  _How?_

  Initially I had tried keeping these lines separate from code block but [Jonatack didn't agree with the changes](bitcoin#21157 (comment)). Harding suggested using [bold/italic in `<pre></pre>`](bitcoin#21157 (comment)). I have used the suggestions from previous PR and added `---`

  This is a part of alternative described in bitcoin#22316

f59bee3 fuzz: execute each file in dir without fuzz engine (Anthony Towns)

Pull request description:

  Phony fuzzing (phuzzing)! Run the fuzz testing code against known inputs to detect errors. Advantage is you can easily test using the existing qa-assets datasets without having to compile with fuzzing enabled; disadvantage is that it doesn't do any actual fuzzing.

  Example usage:

  ```
  $ for a in ${QA_ASSETS}/fuzz_seed_corpus/*; do echo ${a##*/}; done | xargs -P8 -I {} /bin/sh -c "FUZZ={} test/fuzz/fuzz ${QA_ASSETS}/fuzz_seed_corpus/{}"
  No fuzzer for address_deserialize.
  No fuzzer for addrdb.
  No fuzzer for banentry_deserialize.
  addition_overflow: succeeded against 848 files in 0s.
  asmap: succeeded against 981 files in 0s.
  checkqueue: succeeded against 211 files in 0s.
  ...
  ```

  (`-P8` says run 8 of the tasks in parallel)

  If there are failures, the first one will be reported and the program will abort with output like:

  ```
  fuzz: test/fuzz/versionbits.cpp:336: void (anonymous namespace)::versionbits_fuzz_target(FuzzBufferType): Assertion `exp_state != ThresholdState::FAILED' failed.
  Error processing seed "corpus/versionbits/35345ae8e722234095810b1117a29b63af7621af"
  ```

  Rebase of bitcoin#22763, which was a rebase of bitcoin#21496, but also reports the name of the fuzzer and the time taken.

  Fixes bitcoin#21461

3ae7791 refactor: use Span in random.* (pasta)

Pull request description:

  ~This PR does two things~
  1. use a Span<unsigned char> for GetRandBytes and GetStrongRandBytes

  ~2. make GetRand a template for which any integral type can be used, where the default behavior is to return a random integral up to the max of the integral unless a max is provided.
  This simplifies a lot of code from `GetRand(std::numeric_limits<uint64_t>::max()` -> `GetRand<uint64_t>()`~

  MarcoFalke this was inspired by your comment here: bitcoin#24185 (comment) about using Span, so hopefully I'll be able to get this PR done and merged 😂

  ~Also, if requested I could revert the `GetRand(std::numeric_limits<uint64_t>::max()` -> `GetRand<uint64_t>()` related changes if it ends up causing too many conflicts~
