This will become a reusable extensions module. It implements the core parts of Chrome's extension system, and can be used with any host of the [content module](/content/README.md). Some extensions code that is not Chrome-specific still lives in [//chrome/browser/extensions](/chrome/browser/extensions) and will be moved here.
