[3.13] gh-119451: Fix a potential denial of service in http.client (GH-119454) by miss-islington · Pull Request #142139 · python/cpython

…thonGH-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.
