gh-130317: Fix SNaN broken tests on HP PA RISC ( #140452 )
...
While looking at #140028 , I found some unrelated test regressions in the
3.14 cycle. These seem to all come from #130317 . From what I can tell,
that made Python more correct than it was before. According to [0], HP PA
RISC uses 1 for SNaN and thus a 0 for QNaN.

gh-88886: Remove excessive encoding name normalization (GH-137167)
...
The codecs lookup function now performs only minimal normalization of
the encoding name before passing it to the search functions:
all ASCII letters are converted to lower case, spaces are replaced
with hyphens.
Excessive normalization broke third-party codecs providers, like
python-iconv.

gh-124621: Emscripten: Add support for async input devices (GH-136822)
...
This is useful for implementing proper `input()`. It requires the
JavaScript engine to support the wasm JSPI spec which is now stage 4.
It is supported on Chrome since version 137 and on Firefox and node
behind a flag.
We override the `__wasi_fd_read()` syscall with our own variant that
checks for a readAsync operation. If it has it, we use our own async
variant of `fd_read()`, otherwise we use the original `fd_read()`.
We also add a variant of `FS.createDevice()` called
`FS.createAsyncInputDevice()`.
Finally, if JSPI is available, we wrap the `main()` symbol with
`WebAssembly.promising()` so that we can stack switch from `fd_read()`.
If JSPI is not available, attempting to read from an AsyncInputDevice
will raise an `OSError`.
