Wired local file system support for File API. The local file system provider currently exists for ChromeOS builds only.

This CL exposes new extension permission 'fileSystem' that controls access to individual local file system elements from 3rd party extensions. Another new permission 'fileBrowserPrivate' controls access to following API call that retrieves root DOMFileSystem instance for locally exposed folders: 

  chrome.fileBrowserPrivate.requestLocalFileSystem(callback)
