Summary:
This fixes the case that filter policy is missing in SST file, but we
open the table with filter policy on and cache_index_and_filter_blocks =
false. The current behavior is that we will try to load it every time on
Get() but fail.

Summary:
DeleteFile() call was broken for non-default column family. This fixes it. We might need this feature for mongo.
I also introduced a possibility of deleting oldest file in level 0.
Test Plan: added unit test to deletefile_test

Summary:
This diff speeds up DB::Open() and Version creation by limiting the number of FileMetaData initialization. The behavior of Version::UpdateAccumulatedStats() is changed as follows:
* It only initializes the first 20 uninitialized FileMetaData from file. This guarantees the size of the latest 20 files will always be compensated when they have any deletion entries. Previously it may initialize all FileMetaData by loading all files at DB::Open().
* In case none the first 20 files has any data entry, UpdateAccumulatedStats() will initialize the FileMetaData of the oldest file.

Previous to this commit Filters passed as parameters to the
BlockTableConfig are disposed before they should be disposed.
Further Smart pointer usage was corrected.
Java holds now the smart pointer to the FilterPolicy correctly
and cares about freeing underlying c++ structures.
Summary: WriteBatchWithIndex's iterator's SeekToFirst() and SeekToLast() use offset=0 to indicate it is smaller than all the keys, which is wrong. offset=0 will decode a key "" (the header decodes like that). It could be larger than other keys in non-default comparators. Fix it by using a special flag of offset to indicate searching to the beginning of the CF.
Test Plan: Add a unit test that used to fail. Also, add some more tests to related cases, though they don't fail for now.

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
make jtest
