2a383f21f4 Add Bloom/Ribbon hybrid API support (#8679)
Summary:
This is essentially resurrection and fixing of the part of
https://github.com/facebook/rocksdb/issues/8198 that was reverted in https://github.com/facebook/rocksdb/issues/8212, using data added in https://github.com/facebook/rocksdb/issues/8246. Basically,
when configuring Ribbon filter, you can specify an LSM level before which
Bloom will be used instead of Ribbon. But Bloom is only considered for
Leveled and Universal compaction styles and file going into a known LSM
level. This way, SST file writer, FIFO compaction, etc. use Ribbon filter as
you would expect with NewRibbonFilterPolicy.

So that this can be controlled with a single int value and so that flushes
can be distinguished from intra-L0, we consider flush to go to level -1 for
the purposes of this option. (Explained in API comment.)

I also expect the most common and recommended Ribbon configuration to
use Bloom during flush, to minimize slowing down writes and because according
to my estimates, Ribbon only pays off if the structure lives in memory for
more than an hour. Thus, I have changed the default for NewRibbonFilterPolicy
to be this mild hybrid configuration. I don't really want to add something like
NewHybridFilterPolicy because at least the mild hybrid configuration (Bloom for
flush, Ribbon otherwise) should be considered a natural choice.

C APIs also updated, but because they don't support overloading,
rocksdb_filterpolicy_create_ribbon is kept pure ribbon for clarity and
rocksdb_filterpolicy_create_ribbon_hybrid must be called for a hybrid
configuration. While touching C API, I changed bits per key options from
int to double.

BuiltinFilterPolicy is needed so that LevelThresholdFilterPolicy doesn't inherit
unused fields from BloomFilterPolicy.

3e745053b7 Fix MSVC-related build issues (#7439)
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

230bcae7b6 Add a limited support for iteration bounds into BaseDeltaIterator (#5403)
Summary:
For MDEV-19670: MyRocks: key lookups into deleted data are very slow

BaseDeltaIterator remembers iterate_upper_bound and will not let delta_iterator_
walk above the iterate_upper_bound if base_iterator_ is not valid
anymore.

== Rationale ==
The most straightforward way would be to make the delta_iterator
(which is a rocksdb::WBWIIterator) to support iterator bounds. But
checking for bounds has an extra CPU overhead.

So we put the check into BaseDeltaIterator, and only make it when
base_iterator_ is not valid.

(note: We could take it even further, and move the check a few lines
down, and only check iterator bounds ourselves if base_iterator_ is
not valid AND delta_iterator_ hit a tombstone).

3a18bb3e15 BaseDeltaIterator: always check valid() before accessing key() (#4702)
Summary:
Current implementation of `current_over_upper_bound_` fails to take into consideration that keys might be invalid in either base iterator or delta iterator. Calling key() in such scenario will lead to assertion failure and runtime errors.
This PR addresses the bug by adding check for valid keys before calling `IsOverUpperBound()`, also added test coverage for iterate_upper_bound usage in BaseDeltaIterator
Also recommit https://github.com/facebook/rocksdb/pull/4656 (It was reverted earlier due to bugs)

b76398a82b apply ReadOptions.iterate_upper_bound to transaction iterator (#4656)
Summary:
Currently transaction iterator does not apply `ReadOptions.iterate_upper_bound` when iterating. This PR attempts to fix the problem by having `BaseDeltaIterator` enforcing the upper bound check when iterator state is changed.

0bd2ede10e Memory usage stats in C API (#4340)
Summary:
Please consider this small PR providing access to the `MemoryUsage::GetApproximateMemoryUsageByType` function in plain C API. Actually I'm working on Go application and now trying to investigate the reasons of high memory consumption (#4313). Go [wrappers](https://github.com/tecbot/gorocksdb) are built on the top of Rocksdb C API. According to the #706, `MemoryUsage::GetApproximateMemoryUsageByType` is considered as the best option to get database internal memory usage stats, but it wasn't supported in C API yet.
