Summary:
Before running CompactFilesTest.SentinelCompressionType, we should check
whether zlib and snappy are supported.
CompactFilesTest.SentinelCompressionType is a newly added test. Compilation and
linking with different options, e.g. COMPILE_WITH_TSAN, COMPILE_WITH_ASAN, etc.
lead to generation of different binaries. On the one hand, it's not clear why
zlib or snappy is present under ASAN, but not under TSAN. On the other hand,
changing the compilation flags for TSAN or ASAN seems a bigger change worth much
more attention. To unblock the cont-runs, I suggest that we simply add these
two checks at the beginning of the test, as we did for
GeneralTableTest.ApproximateOffsetOfCompressed in table/table_test.cc.
Future actions include invesigating the absence of zlib and snappy when
compiling with TSAN, i.e. COMPILE_WITH_TSAN=1, if necessary.

Summary:
Previously `CompactFiles` with `CompressionType::kDisableCompressionOption` caused program to crash on assertion failure. This PR fixes the crash by adding support for that setting. Now, that setting will cause RocksDB to choose compression according to the column family's options.

Summary:
The patch makes sure that two parallel test threads will operate on different db paths. This enables using open source tools such as gtest-parallel to run the tests of a file in parallel.
Example: ``` ~/gtest-parallel/gtest-parallel ./table_test```

Summary:
this PR fixes a few failed contbuild:
1. ASAN memory leak in Block::NewIterator (table/block.cc:429). the proper destruction of first_level_iter_ and second_level_iter_ of two_level_iterator.cc is missing from the code after the refactoring in https://github.com/facebook/rocksdb/pull/3406
2. various unused param errors introduced by https://github.com/facebook/rocksdb/pull/3662
3. updated comment for `ForceReleaseCachedEntry` to emphasize the use of `force_erase` flag.

Summary:
introduce new methods into a public threadpool interface,
- allow submission of std::functions as they allow greater flexibility.
- add Joining methods to the implementation to join scheduled and submitted jobs with
an option to cancel jobs that did not start executing.
- Remove ugly `#ifdefs` between pthread and std implementation, make it uniform.
- introduce pimpl for a drop in replacement of the implementation
- Introduce rocksdb::port::Thread typedef which is a replacement for std::thread. On Posix Thread defaults as before std::thread.
- Implement WindowsThread that allocates memory in a more controllable manner than windows std::thread with a replaceable implementation.
- should be no functionality changes.

Summary:
GetAndRefSuperVersion() should not be called again in the same thread before ReturnAndCleanupSuperVersion() is called.
If we have a compaction filter that is using DB::Get, This will happen
```
CompactFiles() {
GetAndRefSuperVersion() // -- first call
..
CompactionFilter() {
GetAndRefSuperVersion() // -- second call
ReturnAndCleanupSuperVersion()
}
..
ReturnAndCleanupSuperVersion()
}
```
We solve this issue in the same way Iterator is solving it, but using GetReferencedSuperVersion()

Summary: we should not call ShouldStopBefore() in compaction when the compaction targets level 0. Otherwise, CheckConsistency will fail the assertion of seq number check on level 0.
Test Plan:
make all check -j64
I also manully test that using db_bench to compact files to level 0. Without this line change, the assertion files and multiple files are generated on level 0 after compaction.

Summary: The test `ObsoleteFiles` failed occasionally on slow device. This problem appears on Travis CI several times. The reason is that we did not wait until compaction jobs are finished in the test, while in slower device the background jobs take longer time to finish.
Test Plan: Pass existing tests.

Summary:
We started getting two kinds of crashes since we started using `DB::CompactFiles()`:
(1) `CompactFiles()` fails saying something like "/data/logdevice/4440/shard12/012302.sst: No such file or directory", and presumably makes DB read-only,
(2) DB fails to open saying "Corruption: Can't access /267000.sst: IO error: /data/logdevice/4440/shard1/267000.sst: No such file or directory".
AFAICT, both can be explained by background thread deleting compaction output as "obsolete" while it's being written, before it's committed to manifest. If it ends up committed to the manifest, we get (2); if compaction notices the disappearance and fails, we get (1). The internal tasks t10068021 and t10134177 have some details about the investigation that led to this.
Test Plan: `make -j check`; the new test fails to reopen the DB without the fix

compact_files_test enables SyncPoint but never disable it before
the test terminates. As a result, it might cause heap-use-after-free
error when some code path trying to access the static variable of
SyncPoint when it has already gone out of scope after the main thread
dies.

Summary:
Our existing test notation is very similar to what is used in gtest. It makes it easy to adopt what is different.
In this diff I modify existing [[ https://code.google.com/p/googletest/wiki/Primer#Test_Fixtures:_Using_the_Same_Data_Configuration_for_Multiple_Te | test fixture ]] classes to inherit from `testing::Test`. Also for unit tests that use fixture class, `TEST` is replaced with `TEST_F` as required in gtest.
There are several custom `main` functions in our existing tests. To make this transition easier, I modify all `main` functions to fallow gtest notation. But eventually we can remove them and use implementation of `main` that gtest provides.
```lang=bash
% cat ~/transform
#!/bin/sh
files=$(git ls-files '*test\.cc')
for file in $files
do
if grep -q "rocksdb::test::RunAllTests()" $file
then
if grep -Eq '^class \w+Test {' $file
then
perl -pi -e 's/^(class \w+Test) {/${1}: public testing::Test {/g' $file
perl -pi -e 's/^(TEST)/${1}_F/g' $file

perl -pi -e 's/(int main.*\{)/${1}::testing::InitGoogleTest(&argc, argv);/g' $file
perl -pi -e 's/rocksdb::test::RunAllTests/RUN_ALL_TESTS/g' $file
fi
done
% sh ~/transform
% make format
```
Second iteration of this diff contains only scripted changes.
Third iteration contains manual changes to fix last errors and make it compilable.
Test Plan:
Build and notice no errors.
```lang=bash
% USE_CLANG=1 make check -j55
```
Tests are still testing.
