remove japanese/sj3.
- Use localhost as the default listen address instead of INADDR_ANY.
- Add "servername" directive to serverrc.
- Fix incorrect descriptions in serverrc.
- Take maintainership.
There are several problems with japanese/sj3 port.
1. Original MASTER_SITES don't seem to work any longer.
2. With the current patchset it builds okay, but it is said that it does not work correctly.
3. It does not build under 7-CURRENT (i.e. with gcc4.2).
