• Make freshclam more robust against lagging signature mirrors.

• On-Access 'Extra Scanning', an opt-in minor feature of OnAccess scanning on Linux systems, has been disabled due to a known issue with resource cleanup OnAccessExtraScanning will be re-enabled in a future release when the issue is resolved. In the mean-time, users who enabled the feature in clamd.conf will see a warning informing them that the feature is not active. For details, see: https://bugzilla.clamav.net/show_bug.cgi?id=12048
