A new configuration variable 'core.trustctime' is introduced to allow ignoring st_ctime information when checking if paths in the working tree has changed, because there are situations where it produces too much false positives. Like when file system crawlers keep changing it when scanning and using the ctime for marking scanned files. The default is to notice ctime changes.
