.c Feature to disable field trials in old versions of Chromium. Field trials
tests are (usually) monitored for a fixed length of time. With this change
field trial tests turn them selves off (will use the default group) after
the expiration time (specified in the Field Trial constructor).
BUG=13463
TEST=field_trial_unittests tests this code thorougly. spdy session and testing
field_trials in renderer process would be very helpful. thanks much.
