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.
Test Plan:
make rocksdbjava
make jdb_test
make jdb_bench
java/jdb_bench.sh \
--benchmarks=fillseq,readrandom,readwhilewriting \
--memtablerep=hash_skiplist \
--use_plain_table=1 \
--key_size=20 \
--prefix_size=12 \
--value_size=100 \
--cache_size=17179869184 \
--disable_wal=0 \
--sync=0 \
