tests: dump the http server log after a clone in `test-static-http.t` The 404 message lines don't match `$LOGDATE$`, because that tests for a pattern from the first "-" through a "(GET|PUT|POST)", so glob the timestamp away manually.

tests: force `dumbhttp.py` to write its log file with '\n' on Windows This wasn't causing obvious test failures, but it's the same fix as dbd2d56224d1 for `dummysmtpd.py`, and there's no sense in leaving this problem lying around. (And upon further review, it might have been causing some non-obviously related failures- see the next commit.)

branching: merge stable into default

rust: address 'error: unnecessarily eager cloning of iterator items' Build failed with a reference to https://rust-lang.github.io/rust-clippy/master/index.html#iter_overeager_cloned which seems reasonable. There doesn't seem to be any reason to not follow the advice.

utils: fix resourceutil use of deprecated importlib.resources Some importlib functionality was deprecated in 3.11 . The documentation on https://docs.python.org/3.12/library/importlib.resources.html recommends using the new .files() API that was introduced in 3.9.

utils: avoid using internal _imp.is_frozen() imp has been deprecated for a long time, and were removed in Python 3.12 . As a workaround, we started using the internal _imp. That is ugly and risky. It seems less risky to get the functionality in some other way. Here, we just inspect if 'origin' of the '__main__' module is set and 'frozen'. That seems to work and do the same, and might be better than using the internal _imp directly. This way of inspecting module attributes seems to work in some test cases, but it is a risky change. This level of importlib doesn't have much documentation, a complicated implementation, and we are dealing with some odd use cases.
