As discussed in IRC, we are migrating our IDL files away from the interface-level "LegacyDefaultOptionalArguments" flag and onto argument-level [Optional] or [Optional=CallWithDefaultValue] flags. This patch migrates navigator-related files. This patch changes behavior -- it makes the registerProtocolHandler match Firefox's behavior by making all arguments required and throwing TypeError if required arguments are missing. It also adjusts an existing test to check for the TypeError.
