Summary:
IO uring usage is causing crash test failures due to bad cqe data being returned in the uring. Revert the change to enable IO uring in db_stress, and also re-enable async_io in CircleCI so that code path can be tested. Added the -use_io_uring flag to db_stress that, when false, will wrap the default env in db_stress to emulate async IO.

Summary:
in DBIter::SeekToLast(), key() can be called when iter is invalid and fails the following assertion:
```
./db/db_iter.h:153: virtual rocksdb::Slice rocksdb::DBIter::key() const: Assertion `valid_' failed.
```
This happens when `iterate_upper_bound` and timestamp_lb_ are set. SeekForPrev(*iterate_upper_bound_) positions the iterator on the same user key as *iterate_upper_bound_. A subsequent PrevInternal() call makes the iterator invalid just be the call to key().
This PR fixes this issue by setting updating the seek key to have max sequence number AND max timestamp when the seek key has the same user key as *iterate_upper_bound_.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11223
Test Plan: - Added a unit test that would fail the above assertion before this fix.

Summary:
The problem
-------------
ComparatorOptions is AutoCloseable.
AbstractComparator does not hold a reference to its ComparatorOptions, but the native C++ ComparatorJniCallback holds a reference to the ComparatorOptions’ native C++ options structure. This gets deleted when the ComparatorOptions is closed, either explicitly, or as part of try-with-resources.
Later, the deleted C++ options structure gets used by the callback and the comparator options are effectively random.
The original bug report https://github.com/facebook/rocksdb/issues/8715 was caused by a GC-initiated finalization closing the still-in-use ComparatorOptions. As of 7.0, finalization of RocksDB objects no longer closes them, which worked round the reported bug, but still left ComparatorOptions with a potentially broken lifetime.
In any case, we encourage API clients to use the try-with-resources model, and so we need it to work. And if they don't use it, they leak resources.
The solution
-------------
The solution implemented here is to make a copy of the native C++ options object into the ComparatorJniCallback, rather than a reference. Then the deletion of the native object held by ComparatorOptions is *correctly* deleted when its scope is closed in try/finally.
Testing
-------
We added a regression unit test based on the original test for the reported ticket.
This checkin closes https://github.com/facebook/rocksdb/issues/8715
We expect that there are more instances of "lifecycle" bugs in the Java API. They are a major source of support time/cost, and we note that they could be addressed as a whole using the model proposed/prototyped in https://github.com/facebook/rocksdb/pull/10736

Summary:
The primary purpose of the FactoryFunc was to support LITE mode where the ObjectRegistry was not available. With the removal of LITE mode, the function was no longer required.
Note that the MergeOperator had some private classes defined in header files. To gain access to their constructors (and name methods), the class definitions were moved into header files.

Summary:
From HISTORY.md: Added a subcode of `Status::Corruption`, `Status::SubCode::kMergeOperatorFailed`, for users to identify corruption failures originating in the merge operator, as opposed to RocksDB's internally identified data corruptions.
This is a followup to https://github.com/facebook/rocksdb/issues/11092, where we gave users the ability to keep running a DB despite merge operator failing. Now that the DB keeps running despite such failures, they want to be able to distinguish such failures from real corruptions.

Summary:
The new `MultiGetEntity` API can be used to get a consistent view of
a batch of keys, with the results presented as wide-column entities.
Similarly to `GetEntity` and the iterator's `columns` API, if the entry
corresponding to the key is a wide-column entity to start with, it is
returned as-is, and if it is a plain key-value, it is wrapped into an entity
with a single default column.
Implementation-wise, the new API shares the logic of the batched `MultiGet`
API (via the `MultiGetCommon` methods). Both single-CF and multi-CF
`MultiGetEntity` APIs are provided, and blobs are also supported.

Summary:
The files in `port/`, such as `port_posix.h`, are layering over the system libraries, so shouldn't include the DB-specific files like `options.h`. This PR remove this dependency.
# How
The reason that `port_posix.h` (or `port_win.h`) include `options.h` is to use `CpuPriority`, as there is a method `SetCpuPriority()` in `port_posix.h` that uses `CpuPriority.`
- I think `SetCpuPriority()` make sense to exist in `port_posix.h` as it provides has platform-dependent implementation
- `CpuPriority` enum is defined in `env.h`, but used in `rocksdb/include` and `port/`.
Hence, let us define `CpuPriority` enum in a common file, say `port_defs.h`, such that both directories `rocksdb/include` and `port/` can include.
When we remove this dependency, some other files have compile errors because they can't find definitions, so add header files to resolve

Summary:
The definition of the Cache class should not be needed by the vast majority of RocksDB users, so I think it is just distracting to include it in cache.h, which is primarily needed for configuring and creating caches. This change moves the class to a new header advanced_cache.h. It is just cut-and-paste except for modifying the class API comment.
In general, operations on shared_ptr<Cache> should continue to work when only a forward declaration of Cache is available, as long as all the Cache instances provided are already shared_ptr. See https://stackoverflow.com/a/17650101/454544
Also, the most common way to customize a Cache is by wrapping an existing implementation, so it makes sense to provide CacheWrapper in the public API. This was a cut-and-paste job except removing the implementation of Name() so that derived classes must provide it.
Intended follow-up: consolidate Release() into one function to reduce customization bugs / confusion

Summary:
The patch adds compaction filter support for wide-column entities by introducing
a new `CompactionFilter` API called `FilterV3`. This API is called for regular
key-values, merge operands, and wide-column entities as well. It is passed the
existing value/operand or wide-column structure and it can update the value or
columns or keep/delete/etc. the key-value as usual. For compatibility, the default
implementation of `FilterV3` keeps all wide-column entities and falls back to calling
`FilterV2` for plain old key-values and merge operands.

Summary:
There are a set of jobs using libbenchmark that have linker failures with new default LIB_MODE=shared. This change adds build-linux-run-microbench to the set using LIB_MODE=static to work around the linker failures. I haven't dug into how to fix them.
There is another set of jobs using folly that have linker failures with new default LIB_MODE=shared. I tried fixing these by adding --shared-libs to the folly build, but that doesn't work. It kinda looks like the folly shared libs build is simply broken with the boost dependency:
```
/usr/bin/ld: /tmp/fbcode_builder_getdeps-ZrootZprojectZthird-partyZfollyZbuildZfbcode_builder-root/installed/boost-Z1Z72zV-c0-0f3HkylpzONnr1dsHYDaR2GyTLzYdkck/lib/libboost_filesystem.a(exception.o): relocation R_X86_64_PC32 against symbol `_ZTVN5boost10filesystem16filesystem_errorE' can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: final link failed: bad value
collect2: error: ld returned 1 exit status
```
I tried updating folly to the latest commit and that didn't help. Otherwise, I didn't dig deeper into fixing that so have added build-linux-clang-13-asan-ubsan-with-folly to the set using LIB_MODE=static
Also since I saw a flaky failure (not the first time), increased the timeout on build-linux-unity-and-headers job.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/11168

More efficient build of all unit tests and tools:
```
$ git clean -fdx
$ du -sh .

...
14270.63user 1043.33system 11:19.85elapsed 2252%CPU (0avgtext+0avgdata 1929944maxresident)k

$ /usr/bin/time make -j32 LIB_MODE=shared
...

...
$ du -sh .
5.4G .
$
```
So 1/3 less build time and >90% less space usage.
Individual unit test edit-compile-run is not too different. Modifying an average unit test source file:
```
$ touch db/version_builder_test.cc
$ /usr/bin/time make -j32 LIB_MODE=static version_builder_test
...
34.74user 3.37system 0:38.29elapsed 99%CPU (0avgtext+0avgdata 945520maxresident)k

...
116.26user 43.91system 0:28.65elapsed 559%CPU (0avgtext+0avgdata 675160maxresident)k
```
A little faster with shared.
However, modifying an average DB implementation file has an extra linking step with shared lib:
```
$ touch db/db_impl/db_impl_files.cc
$ /usr/bin/time make -j32 LIB_MODE=static version_builder_test
...
33.17user 5.13system 0:39.70elapsed 96%CPU (0avgtext+0avgdata 945544maxresident)k

```
$ touch db/db_impl/db_impl_files.cc

...
40.80user 4.66system 0:45.54elapsed 99%CPU (0avgtext+0avgdata 1056340maxresident)k
```
A little slower with shared.
On the whole, should be faster and lighter weight because of the many unit test files case

Summary:
LIB_MODE=shared is much more efficient for building all the unit tests but comes with the downside of ugly stack traces, generally missing name demangling and source line info. Searching the internet suggests the reliable way to get stack traces with dynamic loading is with gdb.
This change automatically tries to use gdb to get a stack trace if built with LIB_MODE=shared, and only on Linux because that's where we have the capability to attach to the proper thread. (We could revise the exact conditions in the future.) If there's a failure invoking gdb, it falls back on the old method. Obscure details of making the output reasonable / pretty are in the source code comments.
Based on this, it was easy to make it so that running a test command with ROCKSDB_DEBUG=1 would invoke gdb whenever the stack trace handler was invoked, so I included that.
Intended follow-up: make LIB_MODE=shared the new default `make` build config
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11150
Test Plan:
manual, mostly by injecting an "assert(false)" into a unit test and trying different build modes etc.
Although gdb is slower to start showing stack trace output, it seems overall faster in many if not most cases, presumably because it doesn't reload the symbol table for each stack entry. At least with parallel test runs, having many tests dumping stacks with the old method can take so long it appears to hang the test run.

Fixes https://github.com/facebook/rocksdb/issues/11160
By counting the number of stalls placed on a write queue, we can check in UnlockWAL() whether the stall present at the start of UnlockWAL() has been cleared by the end, or wait until it's cleared.
More details in code comments and new unit test.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11172
Test Plan: unit test added. Yes, it uses sleep to amplify failure on buggy behavior if present, but using a sync point to only allow new behavior would fail with the old code only because it doesn't contain the new sync point. Basically, using a sync point in UnlockWAL() could easily mask a regression by artificially limiting key behaviors. The test would only check that UnlockWAL() invokes code that *should* do the right thing, without checking that it *does* the right thing.

Summary:
Currently, we incorrectly return a Status::Corruption to the MultiGet caller if the file system ReadAsync cannot issue a read and returns an error for some reason, such as IOStatus::NotSupported(). In this PR, we copy the ReadAsync error to the request status so it can be returned to the user.
Tests:
Update existing unit tests and add a new one for this scenario

Summary:
First, we made a small reduction in DURATION_RW as runs were exceeding 1 hour and colliding with subsequent runs.
See Mark Callaghan’s blog post at http://smalldatum.blogspot.com/2023/01/variance-in-rocksdb-benchmarks-on-cloud.html
Configuration parameters which are not consistent with the following email from Mark (see the blog post for more context) have been updated. Where Mark has defined the parameter and we haven't, we define it explicitly. We will need to further monitor for an expected reduction in variance of test times:

Summary:
The patch makes some code quality enhancements in `CompactionIterator::InvokeFilterIfNeeded`
including the renaming of `filter` (which is most likely a remnant of the days before the `FilterV2`
API when the compaction filter used to return a boolean) to `decision`, the removal of some
outdated comments, the elimination of an `error` flag which was only used in one failure case
out of many, as well as some small stylistic improvements. (Some the above will also come in
handy when adding compaction filter support for wide-column entities.)

Summary:
This PR adds logic to the `RunManualCompaction()` loop to check for cancellation before waiting on any conflicting compactions to finish. In case of cancellation, `RunManualCompaction()` no longer waits on conflicting compactions
