Support for new gTLDs

Bug: 13006774

Add support for new generic Top-Level Domains (gTLDs) from ICANN
and deprecate the public APIs that depend on them. Due to the
fast profileration of gTLDs, it has become hard to keep this API
up-to-date. Further it already fails to recognize internal domains.
We thus replace them with simple "any letter sequence" regexps.
