Bug 192872 – Improve release-level page-load logging

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Keith Rollin]

There are a number of reported bugs that are difficult or impossible to track down with our current level of logging. Additionally, some software groups lower in the page-loading stack have requested logging sufficient for tracking a user-visible error message down to the requested resource that caused the message. Add more-comprehensive logging to address these issues/requests.

This is not safe to call for logging, this fires events.
