Reverse-resolve IP in Apache log files

reslog resolves IPs in Apache(8) log files. The result can then be analyzed by another program, like Analog. You can think of it as a replacement of the Apache(8) HostNameLookups directive, in the sense that it resolves client IPs altogether once a day. Resolving takes long time. This is mainly caused by resolving: Network packets may be filtered by firewalls; DNS servers may not be correctly configured; may not be up working; may sit in slow network sections; may be old slow machines; may have traffic jam... etc. All these reasons are out of our control.
