Oops, I didn't rebase all the way. Specifically not past #27605. Will fix.

Added `[[maybe_unused]]` to GetDevURandom.

💬 fanquake commented on pull request "random: drop syscall wrapper usage for getrandom()":
(https://github.com/bitcoin/bitcoin/pull/27699#issuecomment-1554300778)
Added a commit to use `[[maybe_unused]]` on `GetDevURandom`, rather than adding another instance of `(void)GetDevURandom`, to silence a warning.

Added a commit to slightly refactor `getentropy()` detection on macOS, so that we can combine the #ifdefs for the `sys/random.h` include.

1be1c16b70edc5def98eb1903cee08b5d546ba88: Not sure about passing only the translated string here. I think it should be up to the receiving code to decide whether to use `.original` (`bitcoin-chainstate.cpp`) or `.translated` (`node/kernel_notif.cpp`)

974b4293a5f2fe01302c608bf0063e3b52721d0b: Any reason to accept a nullptr for something that can never be null and would lead to UB if it was null? Might be better to use a reference.

c05c15cc7b4fb9052b87bc2f8ea0500cd5218f4e: question for clarity: This commit is not needed and unrelated to kernel? Seems fine to do, just asking.

nit in e850319d5336335a9efbf04307261fb565b7bc68: Would be good to either not touch it or remove the comment?

d96c82a76775b1a41c098e6af60130fbdbba9975: I think you forgot the call to `std::abort`, otherwise it seems that the error isn't treated fatal?

brainstorming nit in d96c82a76775b1a41c098e6af60130fbdbba9975: Not sure about adding test-only code to real code. Would it be a lot more effort to add a test-only derived `MockNotif : node::KernelNotifications` struct that no-ops the fatalError method and use it in the one test?

Same for `AnyPtr`?

Just seemed weird to go from `CBlockIndex*` to `CBlockIndex&` back to `CBlockIndex*`

Not strictly required, but I decided this makes sense, since these are currently in `namespace util` and are just a small amount of header-only code. See the discussion we had here: https://github.com/bitcoin/bitcoin/pull/27636#discussion_r1196623448.

Yea. In general, it's fine for those comments to just be dropped if touching the line.
