The unknown-8bit trick was designed to deal with unknown bytes in an
ASCII message, and it works fine for that. However, I also tried to
extend it to handle bytes that can't be decoded using the charset
specified in an encoded word, and there it fails because there can be
other non-ASCII characters that were *successfully* decoded. The fix is
simple: do the unknown-8bit encoding using the utf-8 codec. This is
especially appropriate since anyone trying to do recovery on an unknown
byte string will probably attempt utf-8 first.

Count the number of Element attribute accesses as a proxy for work done.
With double the amount of work, a ratio of 2.0 indicates linear scaling
and 4.0 quadratic scaling. Use 3.2 as an intermediate threshold.

For optional arguments with required=True, the ArgumentDefaultsHelpFormatter
would always add a " (default: None)" to the end of the help text.
Since that's a bit misleading, it is removed with this commit.

gh-142006: Fix HeaderWriteError in email.policy.default caused by extra newline (GH-142008)
RDM: This fixes a subtle folding error that showed up when a token exactly filled a line and was followed by whitespace and a token with no folding whitespace that was longer than a line. In this particular circumstance the whitespace after the first token got pushed on to the next line, and then stolen to go in front of the next unfoldable token...leaving a completely empty line in the line buffer. That line got turned in to a newline, which is RFC illegal, and the newish security check caught it. The fix is to just delete that empty line from the buffer.

[3.14] gh-119452: Fix a potential virtual memory allocation denial of service in http.server (GH-142216)
The CGI server on Windows could consume the amount of memory specified
in the Content-Length header of the request even if the client does not
send such much data. Now it reads the POST request body by chunks,
therefore the memory consumption is proportional to the amount of sent
data.

gh-119451: Fix a potential denial of service in http.client (GH-119454)
Reading the whole body of the HTTP response could cause OOM if
the Content-Length value is too large even if the server does not send
a large amount of data. Now the HTTP client reads large data by chunks,
therefore the amount of consumed memory is proportional to the amount
of sent data.
