Tidy up extensions stuff and drop fastradio support.
Fastradio was a trick where the ClientHello was padding to at least 1024
bytes in order to trick some mobile radios into entering high-power mode
immediately. After experimentation, the feature is being dropped.
This change also tidies up a bit of the extensions code now that
everything is using the new system.
