Summary:
Previously when building with fbcode and having a system install of liburing, it would link liburing from fbcode statically as well as the system library dynamically. That led to the following error:
```
./db_stress: error while loading shared libraries: liburing.so.1: cannot open shared object file: No such file or directory
```
The fix is to skip the feature test for system liburing when `FBCODE_BUILD=true`.

* Simplify some handling of "CIRCLECI" environment and add "GITHUB_ACTIONS" in the same places
* For jobs that we want to go in pr-jobs or nightly there are disabled "candidate" workflows with draft versions of those jobs.
* ARM jobs are disabled waiting on full GHA support.
* build-linux-java-static needed some special attention to work, due to GLIBC compatibility issues (see comments).

Summary:
**Background** - runtime detection of certain x86 CPU features was added for optimizing CRC32c checksums, where performance is dramatically affected by the availability of certain CPU instructions and code using intrinsics for those instructions. And Java builds with native library try to be broadly compatible but performant.
What has changed is that CRC32c is no longer the most efficient cheecksum on contemporary x86_64 hardware, nor the default checksum. XXH3 is generally faster and not as dramatically impacted by the availability of certain CPU instructions. For example, on my Skylake system using db_bench (similar on an older Skylake system without AVX512):
PORTABLE=1 empty USE_SSE : xxh3->8 GB/s crc32c->0.8 GB/s (no SSE4.2 nor AVX2 instructions)
PORTABLE=1 USE_SSE=1 : xxh3->19 GB/s crc32c->16 GB/s (with SSE4.2 and AVX2)
PORTABLE=0 USE_SSE ignored: xxh3->28 GB/s crc32c->16 GB/s (also some AVX512)
Testing a ~10 year old system, with SSE4.2 but without AVX2, crc32c is a similar speed to the new systems but xxh3 is only about half that speed, also 8GB/s like the non-AVX2 compile above. Given that xxh3 has specific optimization for AVX2, I think we can infer that that crc32c is only fastest for that ~2008-2013 period when SSE4.2 was included but not AVX2. And given that xxh3 is only about 2x slower on these systems (not like >10x slower for unoptimized crc32c), I don't think we need to invest too much in optimally adapting to these old cases.
x86 hardware that doesn't support fast CRC32c is now extremely rare, so requiring a custom build to support such hardware is fine IMHO.
**This change** does two related things:
* Remove runtime CPU detection for optimizing CRC32c on x86. Maintaining this code is non-zero work, and compiling special code that doesn't work on the configured target instruction set for code generation is always dubious. (On the one hand we have to ensure the CRC32c code uses SSE4.2 but on the other hand we have to ensure nothing else does.)
* Detect CPU features in source code, not in build scripts. Although there are some hypothetical advantages to detectiong in build scripts (compiler generality), RocksDB supports at least three build systems: make, cmake, and buck. It's not practical to support feature detection on all three, and we have suffered from missed optimization opportunities by relying on missing or incomplete detection in cmake and buck. We also depend on some components like xxhash that do source code detection anyway.
**In more detail:**
* `HAVE_SSE42`, `HAVE_AVX2`, and `HAVE_PCLMUL` replaced by standard macros `__SSE4_2__`, `__AVX2__`, and `__PCLMUL__`.
* MSVC does not provide high fidelity defines for SSE, PCLMUL, or POPCNT, but we can infer those from `__AVX__` or `__AVX2__` in a compatibility header. In rare cases of false negative or false positive feature detection, a build engineer should be able to set defines to work around the issue.
* `__POPCNT__` is another standard define, but we happen to only need it on MSVC, where it is set by that compatibility header, or can be set by the build engineer.
* `PORTABLE` can be set to a CPU type, e.g. "haswell", to compile for that CPU type.
* `USE_SSE` is deprecated, now equivalent to PORTABLE=haswell, which roughly approximates its old behavior.
Notably, this change should enable more builds to use the AVX2-optimized Bloom filter implementation.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/11419
Test Plan:
existing tests, CI
Manual performance tests after the change match the before above (none expected with make build).
We also see AVX2 optimized Bloom filter code enabled when expected, by injecting a compiler error. (Performance difference is not big on my current CPU.)

Instead of existing calls to ps from gnu_parallel, call a new wrapper that does ps, looks for unit test like processes, and uses pstack or gdb to print thread stack traces. Also, using `ps -wwf` instead of `ps -wf` ensures output is not cut off.
For security, CircleCI runs with security restrictions on ptrace (/proc/sys/kernel/yama/ptrace_scope = 1), and this change adds a work-around to `InstallStackTraceHandler()` (only used by testing tools) to allow any process from the same user to debug it. (I've also touched >100 files to ensure all the unit tests call this function.)

Summary:
The current integration with folly requires cherry-picking folly source files to include in RocksDB for external CI builds. Its not scaleable as we depend on more features in folly, such as coroutines. This PR adds a dependency from RocksDB to the folly library when ```USE_FOLLY``` or ```USE_COROUTINES``` are set. We build folly using the build scripts in ```third-party/folly```, relying on it to download and build its dependencies. A new ```Makefile``` target, ```build_folly```, is provided to make building folly easier.
A new option, ```USE_FOLLY_LITE``` is added to retain the old model of compiling selected folly sources with RocksDB. This might be useful for short-term development.

Summary:
Recently merged CI benchmark scripts were failing.
There has clearly been a major revision of the fields of benchmark output. The upload script expects and sanity-checks the existence of some fields (changes date to conform to OpenSearch format)..., so the script needs to change.
Also add a bit more exception checking to make it more obvious when this happens again.
We have deleted the existing report.tsv from the benchmark machine. An existing report.tsv is appended to by default, so that if the fields change, later rows no longer match the header. This makes for an upload that dies half way through the report file, when the format no longer matches the header.
Re-instate the config.yml for running the benchmarks, so we can once again test it in situ.

Summary:
CircleCI runner based benchmarking. A runner is a dedicate machine configured for CircleCI to perform work on. Our work is a repeatable benchmark, the `benchmark-linux` job in `config.yml`
A runner, in CircleCI terminology, is a machine that is managed by the client (us) rather than running on CircleCI resources in the cloud. This means that we define and configure the iron, and that therefore the performance is repeatable and predictable. Which is what we need for performance regression benchmarking.
On a time schedule (or on commit, during branch development) benchmarks are set off on the runner, and then a script is run `benchmark_log_tool.py` which parses the benchmark output and pushes it into a pre-configured OpenSearch document connected to an OpenSearch dashboard. Members of the team can examine benchmark performance changes on the dashboard.
As time progresses we can add different benchmarks to the suite which gets run.

Summary:
This PR implements a coroutine version of batched MultiGet in order to concurrently read from multiple SST files in a level using async IO, thus reducing the latency of the MultiGet. The API from the user perspective is still synchronous and single threaded, with the RocksDB part of the processing happening in the context of the caller's thread. In Version::MultiGet, the decision is made whether to call synchronous or coroutine code.
A good way to review this PR is to review the first 4 commits in order - de773b3, 70c2f70, 10b50e1, and 377a597 - before reviewing the rest.
TODO:
1. Figure out how to build it in CircleCI (requires some dependencies to be installed)
2. Do some stress testing with coroutines enabled

Summary:
Especially after updating to C++17, I don't see a compelling case for
*requiring* any folly components in RocksDB. I was able to purge the existing
hard dependencies, and it can be quite difficult to strip out non-trivial components
from folly for use in RocksDB. (The prospect of doing that on F14 has changed
my mind on the best approach here.)
But this change creates an optional integration where we can plug in
components from folly at compile time, starting here with F14FastMap to replace
std::unordered_map when possible (probably no public APIs for example). I have
replaced the biggest CPU users of std::unordered_map with compile-time
pluggable UnorderedMap which will use F14FastMap when USE_FOLLY is set.
USE_FOLLY is always set in the Meta-internal buck build, and a simulation of
that is in the Makefile for public CI testing. A full folly build is not needed, but
checking out the full folly repo is much simpler for getting the dependency,
and anything else we might want to optionally integrate in the future.
Some picky details:
* I don't think the distributed mutex stuff is actually used, so it was easy to remove.
* I implemented an alternative to `folly::constexpr_log2` (which is much easier
in C++17 than C++11) so that I could pull out the hard dependencies on
`ConstexprMath.h`
* I had to add noexcept move constructors/operators to some types to make
F14's complainUnlessNothrowMoveAndDestroy check happy, and I added a
macro to make that easier in some common cases.
* Updated Meta-internal buck build to use folly F14Map (always)
No updates to HISTORY.md nor INSTALL.md as this is not (yet?) considered a
production integration for open source users.

Test Plan:
CircleCI tests updated so that a couple of them use folly.
Most internal unit & stress/crash tests updated to use Meta-internal latest folly.
(Note: they should probably use buck but they currently use Makefile.)
Example performance improvement: when filter partitions are pinned in cache,
they are tracked by PartitionedFilterBlockReader::filter_map_ and we can build
a test that exercises that heavily. Build DB with
```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench -benchmarks=fillrandom -num=10000000 -disable_wal=1 -write_buffer_size=30000000 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -partition_index_and_filters
```
and test with (simultaneous runs with & without folly, ~20 times each to see
convergence)
```
TEST_TMPDIR=/dev/shm/rocksdb ./db_bench_folly -readonly -use_existing_db -benchmarks=readrandom -num=10000000 -bloom_bits=16 -compaction_style=2 -fifo_compaction_max_table_files_size_mb=10000 -fifo_compaction_allow_compaction=0 -partition_index_and_filters -duration=40 -pin_l0_filter_and_index_blocks_in_cache
```

Summary:
Various renaming and fixes to get rid of remaining uses of
"backupable" which is terminology leftover from the original, flawed
design of BackupableDB. Now any DB can be backed up, using BackupEngine.

Summary:
Right now, parallelism information passed to "build_tools/rocksdb-lego-determinator no_compression" isn't effective when the test actually runs, as the information is dropped in the middle. Fix it.

Summary:
build_tools/rocksdb-lego-determinator is to generate commands for continuous tests. Recently it changed to by default run tests in parallel with parallelism to be number of CPU processors. This sometimes causes out of space when running so many tests in parallel. Reduce the parallelism by half to temporarily work it around.

Summary:
Fix g++ -march=native detection and reenable s390x in travis
This PR fixes s390x assembler messages:
```
Error: invalid switch -march=z14
Error: unrecognized option -march=z14
```
The s390x travis build was failing with gcc-7 because the assembler on
ubuntu 16.04 is too old to recognize the z14 model so it doesn't work
with -march=native on a z14 machine. It fixes the check for the
-march=native flag so that the assembler will get called and correctly
fail on ubuntu 16.04 which will cause the build to fall back to
-march=z196 which works.
The other changes are needed so builds work more consistently on
s390x:
1. Set make parallelism to 1 for s390x: The default was 4 previously
but I saw frequent internal compiler errors on travis probably due to
low resources. The `platform_dependent` job works more consistently
but is roughly 10 minutes slower although it varies.
2. Remove status_checked jobs, as we are relying on CircleCI for
these now and do not really need platform coverage on them.
