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.

a40ce219b9 Adding merge functions to RocksDBJava
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

 - 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

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.

As native-comparators were not available using JAVA-API. Both built-in comparators

ab3e566699 [Java] Generalize dis-own native handle and refine dispose framework.
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.
