- New upstream version 2.4.5 (tarball created from tag through github
https://github.com/ocsigen/lwt/tags)
- Remove patches which are now upstream.
- Disable ocaml-react support since it breaks the build
(https://github.com/ocsigen/lwt/issues/77)
- Remove manual.pdf for now since tarballs from git tags don't include
the pre-built documentation
