impl: use shorthand initialization, remove old work-around

This switches to using shorthand struct field initialization. It also
removes a work-around for an older version of Rust on Windows.

Finally, we remove an explicit dependency on winapi, which was
required by the aforementioned work-around. However, we do still
indirectly depend on winapi via winapi-util.
