The function2 library is a header-only library which provides support for defining move-only function types, similar to the proposed std::move_only_function in C++23, but with support for additional customization. This appears to be the first time we've vendored code using the boost license, so I've added it to license.html and moz_yaml.py, and have requested review to ensure it is OK to use code with this license.
