Summary:
With this change, we use L1 and up to store compaction outputs in universal compaction.
The compaction pick logic stays the same. Outputs are stored in the largest "level" as possible.
If options.num_levels=1, it behaves all the same as now.
Test Plan:
1) convert most of existing unit tests for universal comapaction to include the option of one level and multiple levels.
2) add a unit test to cover parallel compaction in universal compaction and run it in one level and multiple levels
3) add unit test to migrate from multiple level setting back to one level setting
4) add a unit test to insert keys to trigger multiple rounds of compactions and verify results.

Summary:
Just couple of small changes:
1. removed signal_test, since it doesn't seem useful and we don't even run it as part of `make check`
2. moved perf_context_test to TESTS instead of PROGRAMS
3. `make release` probably shouldn't compile benchmarks. We currently rely on `make release` building db_bench (via Jenkins), so I left db_bench there.
This is just a minor cleanup. We need to rethink our targets since they are a bit messy right now. We can do this during our tech debt week.

The --stats_interval_seconds determines interval for stats reporting
and overrides --stats_interval when set. I also changed tools/benchmark.sh
to report stats every 60 seconds so I can avoid trying to figure out a
good value for --stats_interval per test and per storage device.

Summary:
This makes run_flash_bench.sh configurable. Previously it was hardwired for 1B keys and tests
ran for 12 hours each. That kept me from using it. This makes it configuable, adds more tests,
makes the duration per-test configurable and refactors the test scripts.
Adds the seekrandomwhilemerging test to db_bench which is the same as seekrandomwhilewriting except
the writer thread does Merge rather than Put.
Forces the stall-time column in compaction IO stats to use a fixed format (H:M:S) which makes
it easier to scrape and parse. Also adds an option to AppendHumanMicros to force a fixed format.
Sometimes automation and humans want different format.
Calls thread->stats.AddBytes(bytes); in db_bench for more tests to get the MB/sec summary
stats in the output at test end.
Adds the average ingest rate to compaction IO stats. Output now looks like:

More information on the benchmark output is at https://gist.github.com/mdcallag/db43a58bd5ac624f01e1
For benchmark.sh changes default RocksDB configuration to reduce stalls:
* min_level_to_compress from 2 to 3
* hard_rate_limit from 2 to 3
* max_grandparent_overlap_factor and max_bytes_for_level_multiplier from 10 to 8
* L0 file count triggers from 4,8,12 to 4,12,20 for (start,stall,stop)

This fixes two bugs: "make clean" would never remove the generated
file, util/build_version.cc, and since D33591, would be regenerated
only if it were absent.
* Makefile (clean): Remove the generated file.
(util/build_version.cc): Depend on the no-prereq FORCE target,
so that this target's rules are always run.
Since this is a generated file, make it read-only.
Also, be sure to remove the temporary file when it is the same
as the original.
Test Plan:

Summary:
* Makefile (COMPILE_WITH_TSAN): Avoid a link failure by disabling
-pg when building with TSAN enabled.
Now that "make check" builds all $(PROGRAMS), it is linking
a few programs that were not normally linked before.
For example, this would fail to link with the following diagnostic:
COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench
CCLD log_and_apply_bench
ld: /usr/lib/../lib64/gcrt1.o: relocation R_X86_64_32S against `__libc_csu_fini' can not be used when making a shared object; recompile with -fPIC
/usr/lib/../lib64/gcrt1.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
Makefile:511: recipe for target 'log_and_apply_bench' failed
make: *** [log_and_apply_bench] Error 1
Since removing -pg is sufficient to get past this link
failure, and no one cares about profiling TSAN-enabled
binaries anyway, we will refrain from linking with -pg
when TSAN testing is enabled. Use a new variable, "pg"
which is set to "-pg" in most cases, but that is made
empty when COMPILE_WITH_TSAN is set.
Test Plan:
Now, this succeeds:
rm -f log_and_apply_bench
COMPILE_WITH_TSAN=1 make -j40 log_and_apply_bench
