5615e23d8c [RocksJava] 32-Bit adjustments
Summary:
Before this change overflowing size_t values led to a checked Exception.

After that change:

size_t overflows on 32-Bit architecture throw now an IllegalArgumentException,
which removes the necessity for a developer to catch these Exceptions explicitly.

This is especially an advantage for developers targeting 64-Bit systems because
it is not necessary anymore to catch exceptions which are never thrown on a 64-Bit
system.

Test Plan:
make clean jclean rocksdbjava jtest
mvn -f rocksjni.pom package

4f5a687254 32-Bit RocksJava resolution for jlong overflows
Summary:
This pull request solves the jlong overflow problem on 32-Bit machines as described in https://github.com/facebook/rocksdb/issues/278:

1. There is a new org.rocksdb.test.PlatformRandomHelper to assist in getting random values. For 32 Bit the getLong method is overriden by xpromaches code above. For 64 Bit it behaves as is.
2. The detection should be cross-platform (Windows is supported though it is not ported completely yet).
3. Every JNI method which sets jlong values must check if the value fits into size_t. If it overflows size_t a InvalidArgument Status object will be returned. If its ok a OK Status will be returned.
4. Setters which have this check will throw a RocksDBException if its no OK Status.

Additionally some other parts of code were corrected using the wrong type casts.

Test Plan:
make rocksdbjava
make jtest

94e43a1dfe [Java] Fixed 32-bit overflowing issue when converting jlong to size_t
Summary:
Fixed 32-bit overflowing issue when converting jlong to size_t by
capping jlong to std::numeric_limits<size_t>::max().

Test Plan:
make rocksdbjava
make jtest

ef8b8a8ef6 [Java] Add Java bindings for memtables and sst format.
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 \
