Revert 189134 "Due to privacy concerns about the data contained ..."

> Due to privacy concerns about the data contained in API call arguments, we no longer will log the arguments unless:
> 
> (1) The API call has been whitelisted because we need the arguments and there is no explicit privacy issue w/r/t the arguments of that API call, or
> 
> (2) The browser's activity log testing flag has been set.

> I set up an API_action whitelist with a few preliminary ones. We'll probably need to expand it and add similar whitelists for events.
> 
> For now, this does not affect DOM API calls because we will be taking a whitelisting approach to DOM API calls to begin with.
