Vulnerability Type: DoS 
CWE ID: CWE-399
Summary: Google V8, as used in Google Chrome before 13.0.782.107, does not properly perform const lookups, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted web site.
Commit Message: In chromedriver, add /log url to get the contents of the chromedriver log
remotely. Also add a 'chrome.verbose' boolean startup option.
Remove usage of VLOG(1) in chromedriver. We do not need as complicated
logging as in Chrome.
BUG=85241
