Make generated code more aligned with Google Java style.
- Blank line after opening a message class (but not an enum interface). - Let all code blocks insert blank lines before themselves. This applies to 'package' statement, all message classes, enum classes or constant groups, extensions, bitfields, proto fields (one block per field; i.e. accessors don't have blank lines among them), and basic MessageNano methods. In this case we don't need to guess what the next block is and create blank lines for it. - Fixed some newline/indent errors. - Only one SuppressWarnings("hiding") per file.
