Summary:
In 3.10 the C++ code was extended with a MemEnv implementation. This
is now also available in RocksJava.
Changes:
- Extraced abstract super class Env
- Introduced RocksMemEnv
- Remove unnecessary disposeInternal method. The disposal of the default environment is managed by C++ so there needs to be no disposeInternal method in Java.
- Introduced a RocksMemEnvTest, which is aligned with the C++ equivalent.

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.

Summary:
Within this commit a new AbstractLogger was introduced
which allows to handle log messages at an application level.
Log messages are passed up to Java using a JNI callback.
This allows a Java-Developer to use common Java APIs for log
messages e.g. SLF4J, LOG4J, etc. Within this commit no new
dependencies were introduced, which keeps the RocksDB API clean
and doesn`t force a developer to use a predefined high-level Java API.
Another feature is to dynamically set a custom loggers verbosity at
runtime using its public method `setInfoLogLevel` and to retrieve
the currently active level using the `infoLogLevel` method.

which were failing when C++ assertions were enabled.

In the current implementation DefaultColumnFamily will not disown
the native handle. As the database handles the lease on the native
handle this should be the case.

which should not be derived.

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.

the same functionality but within different classes.
With this commit a template class was introduced to remove
the redundant impelementation to a certain extent.
[RocksJava] Removed todo comment in portal.h
As jclass instances shall not be cached, both
todos are obsolete and can be removed.
[RocksJava] Add missing test to Makefile
[RocksJava] Added tests for uncovered methods

Simple Java Native Objects usually are represented using
the same functionality but within different classes.
With this commit a template class was introduced to remove
the redundant impelementation to a certain extent.
Summary:
Prior to this the native library loader instance didn`t
care about a state. So if library loading was called multiple
times, multiple copies of the shared object were put into
the tmp folder and loaded into the JVM.
This changed within this commit to the following behavior:
- library loading is now synchronized
- library is loaded within the first call
- if loading was successful the library loaded sets a flag
- every subsequent call checks for a boolean flag indicating if there was
already a successful attempt
Test Plan:
- Execute example and watch tmp folder while the example is running
- After this patch only one shared object will be in the tmp folder
Usual tests:
- make rocksdbjava jtest
- mvn -f rocksjni.pom package
