Summary:
Add an option to explicitly disable building shared versions of the
RocksDB libraries. The shared libraries cannot be built in cases where
some dependencies are only available as static libraries. This allows
still building RocksDB in these situations.

Summary:
Especially with non-integral bits/key now supported,
db_crashtest should vary the bloom_bits configuration. The probabilities
look like this:
1/2 chance of a uniform int from 0 to 19. This includes overall 1/40
chance of 0 which disables the bloom filter.
1/2 chance of a float from a lognormal distribution with a median of 10.
This always produces positive values but with a decent chance of < 1
(overall ~1/40) or > 100 (overall ~1/40), the enforced/coerced
implementation limits.

configuration output

Summary:
db_stress_tool.cc now is a giant file. In order to main it easier to improve and maintain, break it down to multiple source files.
Most classes are turned into their own files. Separate .h and .cc files are created for gflag definiations. Another .h and .cc files are created for some common functions. Some test execution logic that is only loosely related to class StressTest is moved to db_stress_driver.h and db_stress_driver.cc. All the files are located under db_stress_tool/. The directory name is created as such because if we end it with either stress or test, .gitignore will ignore any file under it and makes it prone to issues in developements.

Summary:
PR https://github.com/facebook/rocksdb/issues/5937 changed the db_stress tool to also require db_stress_tool.cc,
and updated the Makefile but not the CMakeLists.txt file. This updates
the CMakeLists.txt file so that the CMake build succeeds again.
PR https://github.com/facebook/rocksdb/issues/5950 updated the Makefile build to package db_stress_tool.cc into
its own librocksdb_stress.a library. I haven't done that here since
there didn't really seem to be much benefit: the Makefile-based build
does not install this library.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6117
Test Plan: Confirmed the CMake build succeeds on an Ubuntu 18.04 system.

Recently, a bug was found related to a seek key that is close to SST file boundary. However, it only occurs in a very small chance in db_stress, because the chance that a random key hits SST file boundaries is small. To boost the chance, with 1/16 chance, we pick keys that are close to SST file boundaries.

Summary:
In the previous PR https://github.com/facebook/rocksdb/issues/4788, user can use db_bench mix_graph option to generate the workload that is from the social graph. The key is generated based on the key access hotness. In this PR, user can further model the key-range hotness and fit those to two-term-exponential distribution. First, user cuts the whole key space into small key ranges (e.g., key-ranges are the same size and the key-range number is the number of SST files). Then, user calculates the average access count per key of each key-range as the key-range hotness. Next, user fits the key-range hotness to two-term-exponential distribution (f(x) = f(x) = a*exp(b*x) + c*exp(d*x)) and generate the value of a, b, c, and d. They are the parameters in db_bench: prefix_dist_a, prefix_dist_b, prefix_dist_c, and prefix_dist_d. Finally, user can run db_bench by specify the parameters.
For example:
`./db_bench --benchmarks="mixgraph" -use_direct_io_for_flush_and_compaction=true -use_direct_reads=true -cache_size=268435456 -key_dist_a=0.002312 -key_dist_b=0.3467 -keyrange_dist_a=14.18 -keyrange_dist_b=-2.917 -keyrange_dist_c=0.0164 -keyrange_dist_d=-0.08082 -keyrange_num=30 -value_k=0.2615 -value_sigma=25.45 -iter_k=2.517 -iter_sigma=14.236 -mix_get_ratio=0.85 -mix_put_ratio=0.14 -mix_seek_ratio=0.01 -sine_mix_rate_interval_milliseconds=5000 -sine_a=350 -sine_b=0.0105 -sine_d=50000 --perf_level=2 -reads=1000000 -num=5000000 -key_size=48`

Summary:
DBImpl extends the public GetSnapshot() with GetSnapshotForWriteConflictBoundary() method that takes snapshots specially for write-write conflict checking. Compaction treats such snapshots differently to avoid GCing a value written after that, so that the write conflict remains visible even after the compaction. The patch extends stress tests with such snapshots.

Summary:
In pipeline writing mode, memtable switching needs to wait for memtable writing to finish to make sure that when memtables are made immutable, inserts are not going to them. This is currently done in DBImpl::SwitchMemtable(). This is done after flush_scheduler_.TakeNextColumnFamily() is called to fetch the list of column families to switch. The function flush_scheduler_.TakeNextColumnFamily() itself, however, is not thread-safe when being called together with flush_scheduler_.ScheduleFlush().
This change provides a fix, which moves the waiting logic before flush_scheduler_.TakeNextColumnFamily(). WaitForPendingWrites() is a natural place where the logic can happen.

The patch adds a new command line parameter --decode_blob_index to sst_dump.
If this switch is specified, sst_dump prints blob indexes in a human readable format,

references, and the blob value (and expiration) for inlined blobs.

Summary:
The loop in OperateDb() is getting quite complicated with the introduction of multiple key operations such as MultiGet and Reseeks. This is resulting in a number of corner cases that hangs db_stress due to synchronization problems during reopen (i.e when -reopen=<> option is specified). This PR makes it more robust by ensuring all db_stress threads vote to reopen the DB the exact same number of times.
Most of the changes in this diff are due to indentation.

Summary:
This PR allows for the creation of custom env when using sst_dump. If
the user does not set options.env or set options.env to nullptr, then sst_dump
will automatically try to create a custom env depending on the path to the sst
file or db directory. In order to use this feature, the user must call
ObjectRegistry::Register() beforehand.
Test Plan (on devserver):
```
$make all && make check
```
All tests must pass to ensure this change does not break anything.

Summary:
When multiple operations are performed in a db_stress thread in one loop
iteration, the reopen voting logic needs to take that into account. It
was doing that for MultiGet, but a new option was introduced recently to
do multiple iterator seeks per iteration, which broke it again. Fix the
logic to be more robust and agnostic of the type of operation performed.

Summary:
Two more bug fixes in db_stress:
1. this is to complete the fix of the regression bug causing overflowing when supporting FLAGS_prefix_size = -1.
2. Fix regression bug in compare iterator itself:
(1) when creating control iterator, which used the same read option as the normal iterator by mistake; (2) the logic of comparing has some problems. Fix them.
(3) disable validation for lower bound now, which generated some wildly different results. Disabling it to make normal tests pass while investigating it.
3. Cleaning up snapshots in verification failure cases. Memory is leaked otherwise.

Summary:
When prefix_size = -1, stress test crashes with run time error because of overflow. Fix it by not using -1 but 7 in prefix scan mode.

Summary:
For now, crash_test is not able to report any failure for the logic related to iterator upper, lower bounds or iterators, or reseek. These are features prone to errors. Improve db_stress in several ways:
(1) For each iterator run, reseek up to 3 times.
(2) For every iterator, create control iterator with upper or lower bound, with total order seek. Compare the results with the iterator.
(3) Make simple crash test to avoid prefix size to have more coverage.
(4) make prefix_size = 0 a valid size and -1 to indicate disabling prefix extractor.

this causes assertion failures in BatchedOpsStressTest. This patch
disables them until we can root cause the failures.
