Summary:
Add Java bindings for memtables and sst format. Specifically,
add two abstract Java classses --- MemTableConfig and SstFormatConfig.
Each MemTable / SST implementation should has its own config class
extends MemTableConfig / SstFormatConfig respectively and pass it
to Options via setMemTableConfig / setSstConfig.

Summary:
Make each set function of Options / WriteOptions return its option instance.
Java developers can now easier specify each option like the following:
options.setCreateIfMissing(true)
.setWriteBufferSize(8 * 1024)
.setMaxWriteBufferNumber(3)
.setDisableSeekCompaction(true)
.setBlockSize(64 * 1024)
.setMaxBackgroundCompactions(10);
