Merge revision 1235 changes:

Support cross-origin XMLHttpRequest loads and redirects for custom standard schemes when enabled via the cross-origin whitelist (issue #950).
- Call WebSecurityPolicy::registerURLSchemeAsCORSEnabled() for custom standard schemes.
- Explicitly check the cross-origin whitelist in CefResourceDispatcherHostDelegate::OnRequestRedirected() and add the appropriate CORS headers.
- Improve the CefAddCrossOriginWhitelistEntry() documentation to mention the top-level domain requirement for sub-domain matching.
