gh-124621: Emscripten: Support pyrepl in browser (GH-136931)
Basic support for pyrepl in Emscripten. Limitations:
* requires JSPI
* no signal handling implemented

As followup work, it would be nice to implement a webworker variant
for when JSPI is not available and proper signal handling.

Because it requires JSPI, it doesn't work in Safari. Firefox requires
setting an experimental flag. All the Chromiums have full support since
May. Until we make it work without JSPI, let's keep the original web_example
around.

This directory contains a number of Python programs that are useful
while building or extending Python.

build           Automatically generated directory by the build system
                contain build artifacts and intermediate files.

buildbot        Batchfiles for running on Windows buildbot workers.

c-analyzer      Tools to check no new global variables have been added.

cases_generator Tooling to generate interpreters.

clinic          A preprocessor for CPython C files in order to automate
                the boilerplate involved with writing argument parsing
                code for "builtins".

freeze          Create a stand-alone executable from a Python program.

gdb             Python code to be run inside gdb, to make it easier to
                debug Python itself (by David Malcolm).

i18n            Tools for internationalization. pygettext.py
                parses Python source code and generates .pot files,
                and msgfmt.py generates a binary message catalog
                from a catalog in text format.
