Summary:
In the existing implementation of `ASSERT*`, test termination happens in `~Tester`, which is called when instance of `Tester` goes out of scope. This is the cause of many scan-build bugs.
This diff changes `ASSERT*` to terminate the test immediately. Also added one suppression in `util/signal_test.cc`

before: http://home.fburl.com/~sugak/latest/index.html
after: http://home.fburl.com/~sugak/latest2/index.html
Test Plan:
Modify some test to fail an assertion and make sure that `ASSERT*` terminated the test.
Run `make analyze` and make sure no 'Called C++ object pointer is null' and 'Dereference of null pointer' bugs reported.
Run tests and make sure no failing tests:
```lang=bash
% make check
% USE_CLANG=1 make check
```

Summary:
The code being removed would invoke sed differently to work
around a portability difference in how sed -i works (different
on MacOS). Yet performing a host-type-based ifdef fails when
the tools installed do not match. That sed use was solely to
post-process the .d file. Instead, generate the desired output
directly, by using the compiler's -MT<FILE> option.
* Makefile (%.d: %.cc): With the prior use of Makefile-ifdef'd
sed, when building on MacOS with gnu sed, every run of this rule
would fail with a sed usage error. Also list each .d file as a
dependent.
Test Plan:
Ensure that a selected .d file is the same as before both with
g++ and with clang++. However, note that the new .d files each
contain a new reference to the .d file itself.

Bytes are currently misinterpreted by the Java if the

This diff basically reverts D30249 and also adds a unit test that was failing before this patch.
I have no idea how I didn't catch this terrible bug when writing a diff, sorry about that :(
I think we should redesign our system of keeping track of and deleting files. This is already a second bug in this critical piece of code. I'll think of few ideas.
BTW this diff is also a regression when running lots of column families. I plan to revisit this separately.

Summary:
When DestroyDB() finds a wal file in the DB directory, it assumes it is actually in WAL directory. This can lead to confusion, since it reports IO error when it tries to delete wal file from DB directory. For example: https://ci-builds.fb.com/job/rocksdb_clang_build/296/console
