Summary:
Long awaited CompactionJob class! Move most compaction-related things from DBImpl to CompactionJob, making CompactionJob easier to test and understand.
Currently this is just replicating exactly the same functionality with as little as change as possible. As future work, we should:
1. Add CompactionJob tests (I think I'll do that tomorrow)
2. Reduce CompactionJob's state that it inherits from DBImpl
3. Figure out how to do yielding to flush better. Currently I implemented a callback as we agreed yesterday, but I don't think it's a good long term solution.
This reduces db_impl.cc from 5000+ LOC to 3400!
Test Plan: make check, will add CompactionJob-specific tests, probably also move some tests from db_test to compaction_job_test

Summary:
TestMemEnv simulates all Env APIs using in-memory data structures.
We can use it to speed up db_test run, which is now reduced ~7mins when it is
enabled.
We can also add features to simulate power/disk failures in the next
step
TestMemEnv is derived from helper/mem_env
mem_env can not be used for rocksdb since some of its APIs do not give
the same results as env_posix. And its file read/write is not thread safe

Summary:
ColumnFamilyHandles face the same problem as RocksIterator previously
so used methods were also applied for ColumnFamilyHandles.
Another problem with CF was that Options passed to CFs were
always filled with default values. To enable Merge, all parts
of the database must share the same merge functionality which
is not possible using default values. So from now on every
CF will inherit from db options.
Changes to RocksDB:
- merge can now take also a cfhandle
Changes to MergeTest:
- Corrected formatting
- Included also GC tests
- Extended tests to cover CF related parts
- Corrected paths to cleanup properly within the test process
- Reduced verbosity of the test

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
