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.

Test Plan: Run "make crash_test_with_atomic_flush".

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
```
