This function walks all the fields of a struct, class, or tuple, and calls `body` with the name, offset, and type of each field. `body` can perform any required work or validation, returning `true` to continue walking fields or `false` to stop immediately. (cherry picked from commit 3af1deb)

Ensure that the string that is formed from the `asprintf` call is null-terminated. The `_vsnprintf` call will not null-terminate the string if the length is not sufficient. (cherry picked from commit 37ee73c)
