* java/lang/natString.cc (_Jv_NewStringUtf8Const): Register finalizer.
Recalculate hash, since Utf8Const's hash is only 16 bits.
* java/lang/natString.cc (_Jv_StringFindSlot, rehash): Use high-order
bits of hash to calculate step for chaining.
* java/lang/natString.cc (intern, _Jv_NewStringUtf8Const): Rehash
when 2/3 full, rather than 3/4 full.
