Summary:
Right now, db_stress doesn't cover SeekForPrev(). Add the coverage, which mirrors what we do for Seek().

Test Plan: Run "make crash_test". Do some manual source code hack to simular iterator wrong results and see it caught.

Summary:
In stress test, all iterator verification is turned off is lower bound is enabled. This might be stricter than needed. This PR relaxes the condition and include the case where lower bound is lower than both of seek key and upper bound. It seems to work mostly fine when I run crash test locally.

Summary:
Right now, in db_stress's CF consistency test's TestGet case, if failure happens, we do normal string printing, rather than hex printing, so that some text is not printed out, which makes debugging harder. Fix it by printing hex instead.

Summary:
DBImpl extends the public GetSnapshot() with GetSnapshotForWriteConflictBoundary() method that takes snapshots specially for write-write conflict checking. Compaction treats such snapshots differently to avoid GCing a value written after that, so that the write conflict remains visible even after the compaction. The patch extends stress tests with such snapshots.

Summary:
Right now, in db_stress's iterator tests, we always use the same CF to validate iterator results. This commit changes it so that a randomized CF is used in Cf consistency test, where every CF should have exactly the same data. This would help catch more bugs.

Summary:
Right now in CF consitency stres test's TestGet(), keys are just fetched without validation. With this change, in 1/2 the time, compare all the CFs share the same value with the same key.

Test Plan: Run "make crash_test_with_atomic_flush" and see tests pass. Hack the code to generate some inconsistency and observe the test fails as expected.

Summary:
Since we already parse env_uri from command line and creates custom Env
accordingly, we should invoke the methods of such Envs instead of using
Env::Default().
Test Plan (on devserver):
```
$make db_bench db_stress
$./db_bench -benchmarks=fillseq
./db_stress
```

Summary:
Since SeekForPrev (used by Prev) is not supported by HashSkipList when prefix is used, we disable it when stress testing HashSkipList.
- Change the default memtablerep to skip list.
- Avoid Prev() when memtablerep is HashSkipList and prefix is used.
Test Plan (on devserver):
```
$make db_stress
$./db_stress -ops_per_thread=10000 -reopen=1 -destroy_db_initially=true -column_families=1 -threads=1 -column_families=1 -memtablerep=prefix_hash
$# or simply
$./db_stress
$./db_stress -memtablerep=prefix_hash
```
Results must print "Verification successful".

Summary:
expose db stress test by providing db_stress_tool.h in public header.
This PR does the following:
- adds a new header, db_stress_tool.h, in include/rocksdb/
- renames db_stress.cc to db_stress_tool.cc
- adds a db_stress.cc which simply invokes a test function.
- update Makefile accordingly.
Test Plan (dev server):
```
make db_stress
./db_stress
```
