Summary: Adding in the iterpercent flag to tests.
Test Plan: make crash_test

Summary:
Most code change in this diff is code cleanup/rewrite. The logic changes include:
(1) add universal compaction to db_crashtest2.py
(2) randomly set --test_batches_snapshots to be 0 or 1 in db_crashtest2.py. Old codes always use 1.
(3) use different tmp directory as db directory in different runs. I saw some intermittent errors in my local tests. Use of different tmp directory seems to be able to solve the issue.
Test Plan: Have run "make crashtest" for multiple times. Also run "make all check"

Summary: I changed the db_stress configs, but forgot to update the scripts using the old configs.
Test Plan: 'make blackbox_crash_test' and 'make whitebox_crash_test' start running normally now (I haven't run them til the end, though).

Summary: filter_deletes options introduced in db_stress makes it drop Deletes on key if KeyMayExist(key) returns false on the key. code change was simple and tested so not wasting reviewer's time.

Summary:
I think the check for "error" that I added had caused
false alarm. Fixed that.

Summary:
This is initial version. A few ways in which this could
be extended in the future are:
(a) Killing from more places in source code
(b) Hashing stack and using that hash in determining whether to crash.
This is to avoid crashing more often at source lines that are executed
more often.
(c) Raising exceptions or returning errors instead of killing
Test Plan:
This whole thing is for testing.
