Adding KOI8-U support to JDK-1.5

[Mikhail T.]

Hello!

Below is code to add the support for the KOI8-U charset to JDK.

Please, let me know if I can commit it. It is even simpler to add this
support to earlier JDKs (no need for the additional KOI8_U.java, just
follow the patch author's instructions), but let's start with the
"experimental" JDK-1.5 first.

Thank you!
