This adds the --wait-for-debugger-on-navigation flag which pauses renderers when the target URL is known displaying a message for each. The debug_renderer script is also updated to automatically debug the site passed and unblock all other renderer processes. Documentation in linux/debugging.md is updated to explain how to use the updated script and flag.
