/// Add an entry to the cross-origin access whitelist.
///
/// The same-origin policy restricts how scripts hosted from different origins
/// (scheme + domain + port) can communicate. By default, scripts can only
/// access resources with the same origin. Scripts hosted on the HTTP and HTTPS
/// schemes (but no other schemes) can use the "Access-Control-Allow-Origin"
/// header to allow cross-origin requests. For example,
/// https://source.example.com can make XMLHttpRequest requests on
/// http://target.example.com if the http://target.example.com request returns
/// an "Access-Control-Allow-Origin: https://source.example.com" response
/// header.
///
/// Scripts in separate frames or iframes and hosted from the same protocol and
/// domain suffix can execute cross-origin JavaScript if both pages set the
/// document.domain value to the same domain suffix. For example,
/// scheme://foo.example.com and scheme://bar.example.com can communicate using
/// JavaScript if both domains set document.domain="example.com".
///
/// This method is used to allow access to origins that would otherwise violate
/// the same-origin policy. Scripts hosted underneath the fully qualified
/// |source_origin| URL (like http://www.example.com) will be allowed access to
/// all resources hosted on the specified |target_protocol| and |target_domain|.
/// If |target_domain| is non-empty and |allow_target_subdomains| is false only
/// exact domain matches will be allowed. If |target_domain| contains a top-
/// level domain component (like "example.com") and |allow_target_subdomains| is
/// true sub-domain matches will be allowed. If |target_domain| is empty and
/// |allow_target_subdomains| if true all domains and IP addresses will be
/// allowed.
///
/// This method cannot be used to bypass the restrictions on local or display
/// isolated schemes. See the comments on CefRegisterCustomScheme for more
/// information.
///
/// This function may be called on any thread. Returns false if |source_origin|
/// is invalid or the whitelist cannot be accessed.
