7d817268b9 Managed iterator
Summary:
This is a diff for managed iterator. A managed iterator
is a wrapper around an iterator which saves the options for that
iterator as well as the current key/value so that the underlying iterator
and its associated memory can be released when it is aged out
automatically or on the request of the user. Will provide the automatic release as a follow-up diff.

Test Plan: Managed* tests in db_test and XF tests for managed iterator

dc885c6e95 build: make "make" output readable by default
Summary:
With this change, make now prints a summary line for each
compiler and linker invocation, e.g.,:

  CC       db/builder.o
  CC       db/c.o
  CC       db/column_family.o

To see full commands, insert "V=1" into your make command.
E.g., run "make V=1 all" if you want it to print each command
in its full glory.

$^ is GNU make's abbreviation for the prerequisites of the current target.
These AM_V_... variables expand to some very short string like "CC" or
"LD", by default, so that the output of "make" is readable.  If/when you
want more details, just build with "make V=1 ...", and make will print
each full command as it is executed.  If you prefer to see the noise
all the time, and only want to optionally see the abbreviated output,
set AM_DEFAULT_VERBOSITY=1 in your environment, and then build with
V=0 to see the abbreviated command indicators.

Test Plan:
invoke make a few different ways and observe:
  make clean; make       # abbreviated
  make clean; make V=0   # also abbreviated
  make clean; make V=1   # full detail

4e4b857841 rocksdb: Fix scan-build 'Called C++ object pointer is null' and 'Dereference of null pointer' bugs
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`

scan-build bugs
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

b3fd162267 build: remove unportable use of sed in favor of $(CXX)'s -MT
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.
