Ana Maria Martinez Gomez 3cd97ae9f2 [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("capa"):
    for file_name in file_names:
        # header are only in `.py` and `.toml` files
        if file_name[-3:] not in (".py", "oml"):
            continue
        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)
```

Some files had the copyright headers inside a `"""` comment and needed
manual changes before applying the script. `hook-vivisect.py` and
`pyinstaller.spec` didn't include the license in the header and also
needed manual changes.

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 capa
consistent with other Google projects.

Adapt the linter to work with the new header.

Replace also the copyright text in the `web/public/index.html` file for
consistency.
