Summary:
When adding CompactionFilter and CompactionFilterFactory settings to the Java layer, ColumnFamilyOptions was modified directly instead of ColumnFamilyOptionsInterface. This meant that the old-stye Options monolith was left behind.
This patch fixes that, by:
- promoting the CompactionFilter + CompactionFilterFactory setters from ColumnFamilyOptions -> ColumnFamilyOptionsInterface
- adding getters in ColumnFamilyOptionsInterface
- implementing setters in Options
- implementing getters in both ColumnFamilyOptions and Options
- adding testcases
- reusing a test CompactionFilterFactory by moving it to a common location

Summary:
Transaction::GetForUpdate is extended with a do_validate parameter with default value of true. If false it skips validating the snapshot (if there is any) before doing the read. After the read it also returns the latest value (expects the ReadOptions::snapshot to be nullptr). This allows RocksDB applications to use GetForUpdate similarly to how InnoDB does. Similarly ::Merge, ::Put, ::Delete, and ::SingleDelete are extended with assume_exclusive_tracked with default value of false. It true it indicates that call is assumed to be after a ::GetForUpdate(do_validate=false).
The Java APIs are accordingly updated.

- Made sure the new tickers, `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETED`, are appended at the end of the enum, in case people are relying on the int values.
The change where `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETED` were introduced is unreleased so I believe it is ok to change their ordering.

Summary:
Currently, `Statistics` can record tick by `recordTick()` whose second parameter is an `uint64_t`.
That means tick can only increase.
If we want to reduce tick, we have to work around like `RecordTick(statistics_, NO_ITERATORS, uint64_t(-1));`.
That's kind of a hack.
So, this PR divide `NO_ITERATORS` into two counters `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETE`, making the counters increase only.

CompactRangeOptions are available the CPP API, but not in the Java API. This PR adds CompactRangeOptions to the Java API and adds an overloaded compactRange() method. See https://github.com/facebook/rocksdb/issues/4195 for the original discussion.
This change supports all fields of CompactRangeOptions, including the required enum converters in the JNI portal.
Significant changes:
- Make CompactRangeOptions available in the compactRange() for Java.
- Deprecate other compactRange() methods that have individual option params, like in the CPP code.
- Migrate rocksdb_compactrange_helper() to CompactRangeOptions.
- Add Java unit tests for CompactRangeOptions.

Summary:
This adds support for recovering WriteUnprepared transactions through the following changes:
- The information in `RecoveredTransaction` is extended so that it can reference multiple batches.
- `MarkBeginPrepare` is extended with a bool indicating whether it is an unprepared begin, and this is passed down to `InsertRecoveredTransaction` to indicate whether the current transaction is prepared or not.
- `WriteUnpreparedTxnDB::Initialize` is overridden so that it will rollback unprepared transactions from the recovered transactions. This can be done without updating the prepare heap/commit map, because this is before the DB has finished initializing, and after writing the rollback batch, those data structures should not contain information about the rolled back transaction anyway.
Commit/Rollback of live transactions is still unimplemented and will come later.

Summary:
This is an abstraction for working with custom Comparators implemented in native C++ code from Java. Native code must directly extend `rocksdb::Comparator`. When the native code comparator is compiled into the RocksDB codebase, you can then create a Java Class, and JNI stub to wrap it.
Useful if the C++/JNI barrier overhead is too much for your applications comparator performance.
An example is provided in `java/rocksjni/native_comparator_wrapper_test.cc` and `java/src/main/java/org/rocksdb/NativeComparatorWrapperTest.java`.

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.

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.

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.

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.

Summary:
Major changes in this PR:
* Implement CassandraCompactionFilter to remove expired columns and rows (if all column expired)
* 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.

Summary:
This diff syncs the Histogram Types in the Java API with the ones in C++ API (`statistics.h`), and brings it up-to-date.
I also found that the enum ordering between Java and C++ has gotten out-of-sync, a few years back, with the addition of `SUBCOMPACTION_SETUP_TIME`. So updated the order as well.
`READ_NUM_MERGE_OPERANDS` added in #2373 is needed for Cassandra-on-RocksDB work.
