Summary:
Make compaction picker easier to test.
The basic idea is to separate a minimum subcomponent of Version to VersionStorageInfo, which just responsible to LSM tree. A stub VersionStorageInfo can then be easily created and passed into compaction picker so that we can check the outputs.
It now passes most tests. Still two things need to be done:
(1) deal with the FIFO compaction's file size.
(2) write an example test to make sure the interface can do the job.
Add a compaction_picker_test to make sure compaction picker codes can be easily unit tested.
Test Plan:
Pass all unit tests and compaction_picker_test

Summary:
DBTest has several functions (Reopen(), TryReopen(), ChangeOptins(), etc
that takes a pointer to options), depending on if it is nullptr, it uses
different options underneath. This makes it really hard to track what
options is used in different test case. We should just kill the default
value and make it being passed into explicitly. It is going to be very
hairy. I will start with simple ones.
Test Plan:

Summary:
This diff replaces BlockBasedTable in flush_job_test with TableMock, making it depend on less things and making it closer to an unit test than integration test.
It also introduces a framework to compile mock classes -- Any file named *mock.cc will not be compiled into the build. It will only get compiled into the tests. What way we can mock out most other classes, Version, VersionSet, DBImpl, etc.

This diff has two fixes.
1. Fix the bug where compaction does not fail when RocksDB can't create a new file.
2. When NewWritableFiles() fails in OpenCompactionOutputFiles(), previously such fail-to-created file will be still be included as a compaction output. This patch also fixes this bug.
3. Allow VersionEdit::EncodeTo() to return Status and add basic check.

Summary:
Abstract out FlushProcess and take it out of DBImpl.
This also includes taking DeletionState outside of DBImpl.
Currently this diff is only doing the refactoring. Future work includes:
1. Decoupling flush_process.cc, make it depend on less state
2. Write flush_process_test, which will mock out everything that FlushProcess depends on and test it in isolation

RocksIterator will sometimes Sigsegv on dispose. Mainly thats related
to dispose order. If the related RocksDB instance is freed beforehand
RocksIterator.dispose() will fail.
Within this commit there is a major change to RocksIterator. RocksIterator
will hold a private reference to the RocksDB instance which created the
RocksIterator. So even if RocksDB is freed in the same GC cycle the
RocksIterator instances will be freed prior to related RocksDB instances.
Another aspect targets the dispose logic if the RocksDB is freed previously
and already gc`ed. On dispose of a RocksIterator the dispose logic will check
if the RocksDB instance points to an initialized DB. If not the dispose logic
will not perform any further action.
The crash can be reproduced by using the related test provided within this
commit.
Related information: This relates to @adamretter`s facebook rocksdb-dev group
post about SigSegv on RocksIterator.dispose().
Summary: RocksDB already depends on C++11, so we might as well all the goodness that C++11 provides. This means that we don't need AtomicPointer anymore. The less things in port/, the easier it will be to port to other platforms.
