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:
To understand the bug read t5943287 and check out the new test in column_family_test (ReadDroppedColumnFamily), iter 0.
RocksDB contract allowes you to read a drop column family as long as there is a live reference. However, since our iteration ignores dropped column families, AddLiveFiles() didn't mark files of a dropped column families as live. So we deleted them.
In this patch I no longer ignore dropped column families in the iteration. I think this behavior was confusing and it also led to this bug. Now if an iterator client wants to ignore dropped column families, he needs to do it explicitly.
Test Plan: Added a new unit test that is failing on master. Unit test succeeds now.

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:
This is like readwhilewriting but uses Merge rather than Put in the writer thread.
I am using it for in-progress benchmarks. I don't think the other benchmarks for Merge
cover this behavior. The purpose for this test is to measure read performance when
readers might have to merge results. This will also benefit from work-in-progress
to add skewed key generation.

Summary: WriteBatch and WriteBatchWithIndex now both inherit from a common abstract base class. This makes it easier to write code that is agnostic toward the implementation of the particular write batch. In particular, I plan on utilizing this abstraction to allow transactions to support using either implementation of a write batch.
Test Plan: modified existing WriteBatchWithIndex tests to test new functions. Running all tests.

Summary:
Our existing test notation is very similar to what is used in gtest. It makes it easy to adopt what is different.
In this diff I modify existing [[ https://code.google.com/p/googletest/wiki/Primer#Test_Fixtures:_Using_the_Same_Data_Configuration_for_Multiple_Te | test fixture ]] classes to inherit from `testing::Test`. Also for unit tests that use fixture class, `TEST` is replaced with `TEST_F` as required in gtest.
There are several custom `main` functions in our existing tests. To make this transition easier, I modify all `main` functions to fallow gtest notation. But eventually we can remove them and use implementation of `main` that gtest provides.
```lang=bash
% cat ~/transform
#!/bin/sh
files=$(git ls-files '*test\.cc')
for file in $files
do
if grep -q "rocksdb::test::RunAllTests()" $file
then
if grep -Eq '^class \w+Test {' $file
then

Summary:
gtest does not use exceptions to fail a unit test by design, and `ASSERT*`s are implemented using `return`. As a consequence we cannot use `ASSERT*` in a function that does not return `void` value ([[ https://code.google.com/p/googletest/wiki/AdvancedGuide#Assertion_Placement | 1]]), and have to fix our existing code. This diff does this in a generic way, with no manual changes.
In order to detect all existing `ASSERT*` that are used in functions that doesn't return void value, I change the code to generate compile errors for such cases.
In `util/testharness.h` I defined `EXPECT*` assertions, the same way as `ASSERT*`, and redefined `ASSERT*` to return `void`. Then executed:
```lang=bash
% USE_CLANG=1 make all -j55 -k 2> build.log
% perl -naF: -e 'print "-- -number=".$F[1]." ".$F[0]."\n" if /: error:/' \
build.log | xargs -L 1 perl -spi -e 's/ASSERT/EXPECT/g if $. == $number'
% make format
```
After that I reverted back change to `ASSERT*` in `util/testharness.h`. But preserved introduced `EXPECT*`, which is the same as `ASSERT*`. This will be deleted once switched to gtest.
This diff is independent and contains manual changes only in `util/testharness.h`.
Test Plan:
Make sure all tests are passing.
```lang=bash
% USE_CLANG=1 make check

Summary:
On RocksDB, when there are multiple instances doing
flushes/compactions in the background, the close call takes a long time
because the flushes/compactions need to complete before the database can
shut down. If another instance is using the background threads and the compaction for this instance is in the queue since it has been scheduled, we still cannot shutdown. We now remove the scheduled background tasks which have not yet started running, so that shutdown is speeded up.

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.
