Ticket 47427 - Overflow in nsslapd-disk-monitoring-threshold

Bug Description:  Using ldapsearch shows threshold value as a negative number, even
                  though the feature is working correctly.

Fix Description:  When reading the dse, the server was trying to cast the value as a "int".
                  Changed CONFIG_INT to CONFIG_LONG for nsslapd-disk-monioring-threshold.

Bug Description:  If logging is not set to critical, then the log directories
                  are not checked for available diskspace.

Fix Description:  Remove the "logging_critical" check, and always include the
                  log directories.
