This is a follow-up to the previous part, which actually changes one of these callers to use Array<nsIIDRef> instead of [array] nsIIDPtr. From doing this patch, it seems like we should consider changing the type `nsIIDRef` to instead simply be `nsIID`, and treat it more like the `AString` types from the POV of XPIDL. `nsIIDPtr` would then continue to exist for backwards compatibility, but we can probably remove almost all current consumers over time. Depends on D19175 Differential Revision: https://phabricator.services.mozilla.com/D19176 --HG-- extra : moz-landing-system : lando
