This adds a new nanoseconds field to the FileInfo, populates it during scans and sets the non-truncated time in Chtimes calls. The actual file modification time is defined as modified_s seconds + modified_ns nanoseconds. It's expected that the modified_ns field is <= 1e9 (that is, all whole seconds should go in the modified_s field) but not really enforced. Given that it's an int32 the timestamp can be adjusted += ~2.9 seconds by the modified_ns field... GitHub-Pull-Request: https://github.com/syncthing/syncthing/pull/3431
