[copyright + license] Fix headers

Replace the header from source code files using the following script:
```Python
for dir_path, dir_names, file_names in os.walk("flare-floss"):
    for file_name in file_names:
        try:
            file_path = f"{dir_path}/{file_name}"
            f = open(file_path, "rb+")
            content = f.read()
            m = re.search(OLD_HEADER, content)
            if not m:
                continue
            print(f"{file_path}: {m.group('year')}")
            content = content.replace(m.group(0), NEW_HEADER % m.group("year"))
            f.seek(0)
            f.write(content)
        except:
            continue
```

Some files had the copyright headers inside a `"""` comment and needed
manual changes before applying the script.

The old header had the confusing sentence `All rights reserved`, which
does not make sense for an open source license. Replace the header by
the default Google header that corrects this issue and keep floss
consistent with other Google projects.
