Summary:
In opt mode, assertions are just no-ops. Therefore, we need to report errors instead of just doing an `assert(false)`.

Summary:
`BeginWriteStall()` removes no_slowdown write from the write
list and updates `link_newer`, which makes `CreateMissingNewerLinks()`
thought all write list has valid `link_newer` and failed to create link

It caused flaky test and SegFault for release build.

Summary:
This PR schedules a background thread (shared across all DB instances)
to flush info log every ten seconds. This improves debuggability in case
of RocksDB hanging since it ensures the log messages leading up to the hang
will eventually become visible in the log.
The bulk of this PR is moving monitoring/stats_dump_scheduler* to db/periodic_work_scheduler*
and making the corresponding name changes since now the scheduler handles info
log flushing, not just stats dumping.

Summary:
This exposes to the listener interface whether a compaction was
full or not. Also cleaned up API comment for CompactionJobInfo::stats,
which is not of a nullable type. And since CompactionJob is always
created with non-null CompactionJobStats, removed conditionals on it
being nullptr and instead assert non-null.

Summary:
`DBTest.FileCreationRandomFailure` frequently times out during our
continuous test runs. (It's a case of "stress test posing as unit test.")
The patch reduces the number of iterations to avoid this. Note that
the lower numbers are still sufficient to trigger both flushes and
compactions, so test coverage is still the same.

Summary:
Introduce an new option options.check_flush_compaction_key_order, by default set to true, which checks key order of flush and compaction, and fail the operation if the order is violated.
Also did minor refactor hash checking code, which consolidates the hashing logic to a vlidation class, where the key ordering logic is added.

Test Plan: Add unit tests to validate the check can catch reordering in flush and compaction, and can be properly disabled.

Summary:
This PR addresses some build and functional issues on MSVC targets, as a step towards an eventual goal of having RocksDB build successfully for Windows on ARM64.
Addressed issues include:
- BitsSetToOne and CountTrailingZeroBits do not compile on non-x64 MSVC targets. A fallback implementation of BitsSetToOne when Intel intrinsics are not available is added, based on the C++20 `<bit>` popcount implementation in Microsoft's STL.
- The implementation of FloorLog2 for MSVC targets (including x64) gives incorrect results. The unit test easily detects this, but CircleCI is currently configured to only run a specific set of tests for Windows CMake builds, so this seems to have been unnoticed.
- AsmVolatilePause does not use YieldProcessor on Windows ARM64 targets, even though it is available.
- When CondVar::TimedWait calls Microsoft STL's condition_variable::wait_for, it can potentially trigger a bug (just recently fixed in the upcoming VS 16.8's STL) that deadlocks various tests that wait for a timer to execute, since `Timer::Run` doesn't get a chance to execute before being blocked by the test function acquiring the mutex.
- In c_test, `GetTempDir` assumes a POSIX-style temp path.
- `NormalizePath` did not eliminate consecutive POSIX-style path separators on Windows, resulting in test failures in e.g., wal_manager_test.
- Various other test failures.
In a followup PR I hope to modify CircleCI's config.yml to invoke all RocksDB unit tests in Windows CMake builds with CTest, instead of the current use of `run_ci_db_test.ps1` which requires individual tests to be specified and is missing many of the existing tests.
Notes from peterd: FloorLog2 is not yet used in production code (it's for something in progress). I also added a few more inexpensive platform-dependent tests to Windows CircleCI runs. And included facebook/folly#1461 as requested

Summary:
We would like to build a shared library with all fbcode dependencies statically linked within.
This resulting .so should not drop any symbols definitions in the building process.
To ensure that, we use `link_whole=True` according to
https://buck.build/rule/cxx_library.html#link_whole.
Since `link_whole` is `False` by default, adding a `link_whole=False` to existing libraries won't
change any behavior.

deactivating the filesystem.
