Upstream code doesn't do regular releases, so we need to regularly
sync the code from the upstream repository. This is synchronization up
to the commit f8d0513 from Jan 29, 2024.
PicoHTTPParser is a tiny, primitive, fast HTTP request/response parser.
Unlike most parsers, it is stateless and does not allocate memory by
itself. All it does is accept pointer to buffer and the output
structure, and setups the pointers in the latter to point at the
necessary portions of the buffer.
