Summary:
Add Java-side copy constructors for:
- Options
- DBOptions
- ColumnFamilyOptions
- WriteOptions

along with unit tests to assert the copy worked.

NOTE: Unit tests are failing in travis but it looks like a global timeout issue. These tests pass.

d394a6bb48 Add a ticker stat for number of keys skipped during iteration
Summary:
This diff adds a new ticker stat, NUMBER_ITER_SKIP, to count the
number of internal keys skipped during iteration. Keys can be skipped
due to deletes, or lower sequence number, or higher sequence number
than the one requested.

Also, fix the issue when StatisticsData is naturally aligned on cacheline boundary,
padding becomes a zero size array, which the Windows compiler doesn't
like. So add a cacheline worth of padding in that case to keep it happy.
We cannot conditionally add padding as gcc doesn't allow using sizeof
in preprocessor directives.

57fcdc264a added missing subcodes and improved error message for missing enum values
Summary:
Java's `Status.SubCode` was out of sync with `include/rocksdb/status.h:SubCode`.

When running out of disc space this led to an `IllegalArgumentException` because of an invalid status code, rather than just returning the corresponding status code without an exception.

I added the missing status codes.

By this, we keep the behaviour of throwing an `IllegalArgumentException` in case of newly added status codes that are defined in C but not in Java.

We could think of an alternative strategy: add in Java another code "UnknownCode" which acts as a catch-all for all those status codes that are not yet mirrored from C to Java. This approach would never throw an exception but simply return a non-OK status-code.

I think the current approach of throwing an Exception in case of a C/Java inconsistency is fine, but if you have some opinion on the alternative strategy, then feel free to comment here.

e4234fbdcf collecting kValue type tombstone
Summary:
In our testing cluster, we found large amount tombstone has been promoted to kValue type from kMerge after reaching the top level of compaction. Since we used to only collecting tombstone in merge operator, those tombstones can never be collected.

This PR addresses the issue by adding a GC step in compaction filter, which is only for kValue type records. Since those record already reached the top of compaction (no earlier data exists) we can safely remove them in compaction filter without worrying old data appears.

This PR also removes an old optimization in cassandra merge operator for single merge operands.  We need to do GC even on a single operand, so the optimation does not make sense anymore.

382277d0fe JNI support for ReadOptions::iterate_upper_bound
Summary:
Plumbed ReadOptions::iterate_upper_bound through JNI.

Made the following design choices:
* Used Slice instead of AbstractSlice due to the anticipated usecase (key / key prefix). Can change this if anyone disagrees.
* Used Slice instead of raw byte[] which seemed cleaner but necessitated the package-private handle-based Slice constructor. Followed WriteBatch as an example.
* We need a copy constructor for ReadOptions, as we create one base ReadOptions for a particular usecase and clone -> change the iterate_upper_bound on each slice operation. Shallow copy seemed cleanest.
* Hold a reference to the upper bound slice on ReadOptions, in contrast to Snapshot.

044a71e27e Add iterator's SeekForPrev functionality to the java-api
Summary:
As discussed in #2742 , this pull-requests brings the iterator's [SeekForPrev()](https://github.com/facebook/rocksdb/wiki/SeekForPrev) functionality to the java-api. It affects all locations in the code where previously only Seek() was supported.

All code changes are essentially a copy & paste of the already existing implementations for Seek().
**Please Note**: the changes to the C++ code were applied without fully understanding its effect, so please take a closer look. However, since Seek() and SeekForPrev() provide exactly the same signature, I do not expect any mistake here.

The java-tests are extended by new tests for the additional functionality.

Compilation (`make rocksdbjavastatic`) and test (`java/make test`) run without errors.

78cb6b6112 Provide byte[] version of SstFileWriter.merge to reduce GC Stall
Summary:
In Java API, `SstFileWriter.put/merge/delete` takes `Slice` type of key and value, which is a Java wrapper object around C++ Slice object.  The Slice object inherited [ `finalize`](3c327ac2d0/java/src/main/java/org/rocksdb/AbstractNativeReference.java (L69)) method, which [added huge overhead](https://softwareengineering.stackexchange.com/questions/288715/is-overriding-object-finalize-really-bad/288753#288753) to JVM while creating new SstFile.

To address this issue, this PR overload the merge method to take Java byte array instead of the Slice object, and added unit test for it.

We also benchmark these two different merge function, where we could see GC Stall reduced from 50%  to 1%, and the throughput increased from 50MB to 200MB.

* Move cassandra related code from utilities/merge_operators/cassandra to utilities/cassandra/*
* Switch to use shared_ptr<> from uniqu_ptr for Column membership management in RowValue. Since columns do have multiple owners in Merge and GC process, use shared_ptr helps make RowValue immutable.
* Rename cassandra_merge_test to cassandra_functional_test and add two TTL compaction related tests there.

c6d464a9da Fixed various memory leaks and Java 8 JNI Compatibility
Summary:
I have manually audited the entire RocksJava code base.

Sorry for the large pull-request, I have broken it down into many small atomic commits though.

My initial intention was to fix the warnings that appear when running RocksJava on Java 8 with `-Xcheck:jni`, for example when running `make jtest` you would see many errors similar to:

As a result of fixing these, I realised we were not r

eb912a927e Remove disableDataSync option
Summary:
Remove disableDataSync, and another similarly named disable_data_sync options.
This is being done to simplify options, and also because the performance gains of this feature can be achieved by other methods.
