2082a7d745 [Java] Temporary set the number of BG threads based on the number of BG compactions.
Summary:
Before the Java binding for Env is ready, Java developers have no way to
control the number of background threads.  This diff provides a temporary
solution where RocksDB.setMaxBackgroundCompactions() will affect the
number of background threads.

Note that once Env is ready.  Changes made in this diff should be reverted.

05979493d6 [Java] Enable filluniquerandom, readseq, BloomFilter, and 70+ command-line options to DbBenchmark.java
Summary:
* Add filluniquerandom
* Add readseq, implemented using iterator.
* Realize most command-line-arguments from db_bench.cc (70+).
* Some code are commented out as some of the options in Options
  not yet have Java bindings.
* Add default option to DbBenchmark.
* RocksDB will now take the ownership of all c++ raw-pointers from Options, which includes a c++ raw-pointer for Filter.

    DEFAULT: 0.5

  --use_existing_db
    If true, do not destroy the existing database.  If you set this
        flag and also specify a benchmark that wants a fresh database,  that benchmark will fail.
    DEFAULT: false

  --num
    Number of key/values to place in database.
    DEFAULT: 1000000

  --threads
    Number of concurrent threads to run.
    DEFAULT: 1

  --reads
    Number of read operations to do.  If negative, do --nums reads.

  --key_size
    The size of each key in bytes.
    DEFAULT: 16

  --value_size
    The size of each value in bytes.
    DEFAULT: 100

  --write_buffer_size

0d463a3685 Add a jni library for rocksdb which supports Open, Get, Put, and Close.
Summary:
This diff contains a simple jni library for rocksdb which supports open, get,
put and closeusing default options (including Options, ReadOptions, and
WriteOptions.)  In the usual case, Java developers can use the c++ rocksdb
library in the way similar to the following:

    RocksDB db = RocksDB.open(path_to_db);
    ...
    db.put("hello".getBytes(), "world".getBytes();
    byte[] value = db.get("hello".getBytes());
    ...
    db.close();

Specifically, this diff has the following major classes:

* RocksDB: a Java wrapper class which forwards the operations
  from the java side to c++ rocksdb library.
* RocksDBException: ncapsulates the error of an operation.
  This exception type is used to describe an internal error from
  the c++ rocksdb library.

This diff also include a simple java sample code calling c++ rocksdb library.

To build the rocksdb jni library, simply run make jni, and make jtest will try to
build and run the sample code.

Note that if the rocksdb is not built with the default glibc that Java uses,
java will try to load the wrong glibc during the run time.  As a result,
the sample code might not work properly during the run time.

Test Plan:
* make jni
* make jtest
