nit: I wonder whether we could give this content setting a more descriptive name
e.g. CONTENT_SETTINGS_TYPE_UNSANDBOXED_PLUGINS? or something similar. Your call.

At least internally, I'd like to keep the term "PPAPI broker", as that is
exactly what it is (unsandboxed plug-in could mean NPAPI plug-in, for example,
or even an unsandboxed Pepper plug-in).

       return setting == CONTENT_SETTING_ASK;
     default:
       return false;
