TokyoCabinet & Native Libs for Java

TokyoCabinet remains a workhorse key-value store that still represents excellent performance vs. modern popular embedded key-value stores such as LevelDB or RocksDB. This is a published version of the library for Java 8+, along with native libs that are automatically extracted at runtime.

The Java library is as unmodified as possible from the original TokyoCabinet, but a few changes were made to automatically extract the library at runtime.
