Drop root privileges earlier. Close syslog more later in imap-master when forking new processes, so that any errors get logged. Make sure that all errors show up in log files - use specific exit status codes if we can't write to log file. Make sure imap and login processes always drop root privileges even if master process didn't ask for it for some reason. putenv() wasn't verified to succeed - luckily we never allowed large user given data there.
