Summary:
With the patch, thread pool size will be automatically increased if DB's options ask for more parallelism of compactions or flushes.
Too many users have been confused by the API. Change it to make it harder for users to make mistakes
Test Plan: Add two unit tests to cover the function.

Summary:
This diff is revamping our build tools:
1) Use third-party2 instead of third-party
2) consolidate clang and gcc scripts together, lots of duplication there
3) remove hdfs libs, we never compile rocksdb with them
clang compilation doesn't work yet. It doesn't work in master either. I plan to fix it soon, but I just spent 2 hours trying to make it work and failed. I'll ask experts.
Test Plan: compiles with gcc

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

make all -j32

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
