Summary:
Separate a new class InternalIterator from class Iterator, when the look-up is done internally, which also means they operate on key with sequence ID and type.
This change will enable potential future optimizations but for now InternalIterator's functions are still the same as Iterator's.
At the same time, separate the cleanup function to a separate class and let both of InternalIterator and Iterator inherit from it.
Test Plan: Run all existing tests.

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.

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
Test environment: Ubuntu 14.04(LTS, x64), Java 1.7.0_65(OpenJDK IcedTea 2.5.2), g++ 4.8.2, kernel 3.13.0-35-generix
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

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

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.
