Summary:
Bytes are currently misinterpreted by the Java if the
byte array contains zero bytes within its content. For Strings
thats usually not useful. As the Java API allows every kind
of byte array values it might be the case that zero padding might
happen.

Expose GetIntProperty methods to RocksJava. As the integer(64-Bit)
value is no integer in Java the method is aligned with the return
type which is long.
Summary:
We need to turn on -Wshorten-64-to-32 for mobile. See D1671432 (internal phabricator) for details.
This diff turns on the warning flag and fixes all the errors. There were also some interesting errors that I might call bugs, especially in plain table. Going forward, I think it makes sense to have this flag turned on and be very very careful when converting 64-bit to 32-bit variables.

Summary:
ColumnFamilyHandles face the same problem as RocksIterator previously
so used methods were also applied for ColumnFamilyHandles.
Another problem with CF was that Options passed to CFs were
always filled with default values. To enable Merge, all parts
of the database must share the same merge functionality which
is not possible using default values. So from now on every
CF will inherit from db options.
Changes to RocksDB:
- merge can now take also a cfhandle
Changes to MergeTest:
- Corrected formatting
- Included also GC tests
- Extended tests to cover CF related parts
- Corrected paths to cleanup properly within the test process
- Reduced verbosity of the test

Summary:
Added support for the merge operation to RocksJava.
You can specify a merge function to be used on the current database.
The merge function can either be one of the functions defined in
utilities/merge_operators.h, which can be specified through its
corresponding name, or a user-created function that needs to be
encapsulated in a JNI object in order to be used. Examples are
provided for both use cases.
Test Plan: There are unit test in MergeTest.java

This commit includes the support for the following functionalities:
- Single Get/Put operations
- WriteBatch operations
- Single iterator functionality
- Open database with column families
- Open database with column families Read/Only
- Create column family
- Drop column family
- Properties of column families
- Listing of column families
- Fully backwards comptabile implementation
- Multi Iterator support
- MultiGet
- KeyMayExist
- Option to create missing column families on open
In addition there is are two new Tests:
- Test of ColumnFamily functionality
- Test of Read only feature to open subsets of column families
- Basic test to test the KeyMayExist feature
What is not supported currently using RocksJava:
- Custom ColumnFamilyOptions
The following targets work as expected:
- make rocksdbjava
- make jtest

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.

Summary:
1. Move disOwnNativeHandle() function from RocksDB to RocksObject
to allow other RocksObject to use disOwnNativeHandle() when its
ownership of native handle has been transferred.
2. RocksObject now has an abstract implementation of dispose(),
which does the following two things. First, it checks whether
both isOwningNativeHandle() and isInitialized() return true.
If so, it will call the protected abstract function dispose0(),
which all the subclasses of RocksObject should implement. Second,
it sets nativeHandle_ = 0. This redesign ensure all subclasses
of RocksObject have the same dispose behavior.
3. All subclasses of RocksObject now should implement dispose0()
instead of dispose(), and dispose0() will be called only when
isInitialized() returns true.

While the finalizer of a RocksObject will release its c++ resource, it is
