* Returns the public suffix of a URI. A public suffix is the highest-level domain

* because the .uk TLD does not allow the registration of domains at the
* second level ("bbc.uk" is forbidden).
*
* The public suffix will be returned encoded in ASCII/ACE and will be normalized
* according to RFC 3454, i.e. the same encoding returned by nsIURI::GetAsciiHost().
* If consumers wish to compare the result of this method against the host from
* another nsIURI, the host should be obtained using nsIURI::GetAsciiHost().
* In the case of nested URIs, the innermost URI will be used.

* @throws NS_ERROR_UNEXPECTED
* or other error returned by nsIIDNService::normalize when
* the hostname contains characters disallowed in URIs
* @throws NS_ERROR_HOST_IS_IP_ADDRESS
