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:

```
WARNING in native method: JNI call made without checking exceptions when required to from CallObjectMethod
WARNING in native method: JNI call made without checking exceptions when required to from CallVoidMethod
WARNING in native method: JNI call made without checking exceptions when required to from CallStaticVoidMethod
...
```

A few of those warnings still remain, however they seem to come directly from the JVM and are not directly related to RocksJava; I am in contact with the OpenJDK hostpot-dev mailing list about these - http://mail.openjdk.java.net/pipermail/hotspot-dev/2017-February/025981.html.

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

03d433ee65 [RocksJava] Fixed test failures
Summary:
The option bottommost_level_compaction was introduced lately.
This option breaks the Java API behavior. To prevent the library
from doing so we set that option to a fixed value in Java.

In future we are going to remove that portion and replace the
hardcoded options using a more flexible way.

Fixed bug introduced by WriteBatchWithIndex Patch

Lately icanadi changed the behavior of WriteBatchWithIndex.
See commit: 821cff114e

This commit solves problems introduced by above mentioned commit.

Test Plan:
make rocksdbjava
make jtest
