Add support for complete isolation of storage and permissions (cache, cookies, localStorage, access grants, etc) on a per-request-context basis (issue #1044).

- CefRequestContext instances can be configured using a new CefRequestContextSettings structure passed to CefRequestContext::CreateContext.
- Scheme registration is now per-request-context using new CefRequestContext::RegisterSchemeHandlerFactory and ClearSchemeHandlerFactories methods.
- Cookie managers are now per-request-context by default and can be retrieved using a new CefRequestContext::GetDefaultCookieManager method.
- CefURLRequest::Create now accepts an optional CefRequestContext argument for associating a URL request with a context (browser process only).
- The CefRequestContextHandler associated with a CefRequestContext will not be released until all objects related to that context have been destroyed.
- When the cache path is empty an in-memory cache ("incognito mode") will be used for storage and no data will be persisted to disk.
- Add CefSettings.user_data_path which specifies the location where user data such as spell checking dictionary files will be stored on disk.
- Add asynchronous callbacks for all CefCookieManager methods.
- Add PK_LOCAL_APP_DATA and PK_USER_DATA path keys for retrieving user directories via CefGetPath.
- cefclient: Add "New Window" test that creates a new window unrelated to existing windows. When used in combination with `--request-context-per-browser` the new window will be given a new and isolated request context.
