Summary:
This PR adds timestamp support to a read only DB instance opened as `DBImplReadOnly`. A follow up PR will add the same support to `CompactedDBImpl`.
With this, read only database has these timestamp related APIs:
`ReadOptions.timestamp` : read should return the latest data visible to this specified timestamp
`Iterator::timestamp()` : returns the timestamp associated with the key, value
`DB:Get(..., std::string* timestamp)` : returns the timestamp associated with the key, value in `timestamp`
Test plan (on devserver):
```
$COMPILE_WITH_ASAN=1 make -j24 all
$./db_with_timestamp_basic_test --gtest_filter=DBBasicTestWithTimestamp.ReadOnlyDB*

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
No regression in synchronous MultiGet between this branch and main -

Summary:
Essentially refactored the RangeMayExist implementation in
FullFilterBlockReader to FilterBlockReaderCommon so that it applies to
partitioned filters as well. (The function is not called for the
block-based filter case.) RangeMayExist is essentially a series of checks
around a possible PrefixMayExist, and I'm confident those checks should
be the same for partitioned as for full filters. (I think it's likely
that bugs remain in those checks, but this change is overall a simplifying
one.)

Summary:
Start tracking SST unique id in MANIFEST, which is used to verify with
SST properties to make sure the SST file is not overwritten or
misplaced. A DB option `try_verify_sst_unique_id` is introduced to
enable/disable the verification, if enabled, it opens all SST files
during DB-open to read the unique_id from table properties (default is
false), so it's recommended to use it with `max_open_files = -1` to
pre-open the files.

Summary:
### Context:
Background compactions and flush generate large reads and writes, and can be long running, especially for universal compaction. In some cases, this can impact foreground reads and writes by users.
### Solution
User, Flush, and Compaction reads share some code path. For this task, we update the rate_limiter_priority in ReadOptions for code paths (e.g. FindTable (mainly in BlockBasedTable::Open()) and various iterators), and eventually update the rate_limiter_priority in IOOptions for FSRandomAccessFile.
**This PR is for the Read path.** The **Read:** dynamic priority for different state are listed as follows:
| State | Normal | Delayed | Stalled |
| ----- | ------ | ------- | ------- |
| Flush (verification read in BuildTable()) | IO_USER | IO_USER | IO_USER |
| Compaction | IO_LOW | IO_USER | IO_USER |
| User | User provided | User provided | User provided |
We will respect the read_options that the user provided and will not set it.
The only sst read for Flush is the verification read in BuildTable(). It claims to be "regard as user read".
**Details**
1. Set read_options.rate_limiter_priority dynamically:
- User: Do not update the read_options. Use the read_options that the user provided.
- Compaction: Update read_options in CompactionJob::ProcessKeyValueCompaction().
- Flush: Update read_options in BuildTable().
2. Pass the rate limiter priority to FSRandomAccessFile functions:
- After calling the FindTable(), read_options is passed through GetTableReader(table_cache.cc), BlockBasedTableFactory::NewTableReader(block_based_table_factory.cc), and BlockBasedTable::Open(). The Open() needs some updates for the ReadOptions variable and the updates are also needed for the called functions, including PrefetchTail(), PrepareIOOptions(), ReadFooterFromFile(), ReadMetaIndexblock(), ReadPropertiesBlock(), PrefetchIndexAndFilterBlocks(), and ReadRangeDelBlock().
- In RandomAccessFileReader, the functions to be updated include Read(), MultiRead(), ReadAsync(), and Prefetch().
- Update the downstream functions of NewIndexIterator(), NewDataBlockIterator(), and BlockBasedTableIterator().

Summary:
This is similar to https://github.com/facebook/rocksdb/issues/9862, including the following fixes/refactoring:
1. If OPTIONS file is specified via `-options_file`, majority of options will be loaded from the file. We should not
overwrite options that have been loaded from the file. Instead, we configure only fields of options which are
shared objects and not set by the OPTIONS file. We also configure a few fields, e.g. `create_if_missing` necessary
for stress test to run.
2. Refactor options initialization into three functions, `InitializeOptionsFromFile()`, `InitializeOptionsFromFlags()`
and `InitializeOptionsGeneral()` similar to db_bench. I hope they can be shared in the future. The high-level logic is
as follows:
```cpp
if (!InitializeOptionsFromFile(...)) {
InitializeOptionsFromFlags(...);
}
InitializeOptionsGeneral(...);
```
3. Currently, the setting for `block_cache_compressed` does not seem correct because it by default specifies a
size of `numeric_limits<size_t>::max()` ((size_t)-1). According to code comments, `-1` indicates default value,
which should be referring to `num_shard_bits` argument.
4. Clarify `fail_if_options_file_error`.

Summary:
### Context:
Background compactions and flush generate large reads and writes, and can be long running, especially for universal compaction. In some cases, this can impact foreground reads and writes by users.
From the RocksDB perspective, there can be two kinds of rate limiters, the internal (native) one and the external one.
- The internal (native) rate limiter is introduced in [the wiki](https://github.com/facebook/rocksdb/wiki/Rate-Limiter). Currently, only IO_LOW and IO_HIGH are used and they are set statically.
- For the external rate limiter, in FSWritableFile functions, IOOptions is open for end users to set and get rate_limiter_priority for their own rate limiter. Currently, RocksDB doesn’t pass the rate_limiter_priority through IOOptions to the file system.
### Solution
During the User Read, Flush write, Compaction read/write, the WriteController is used to determine whether DB writes are stalled or slowed down. The rate limiter priority (Env::IOPriority) can be determined accordingly. We decided to always pass the priority in IOOptions. What the file system does with it should be a contract between the user and the file system. We would like to set the rate limiter priority at file level, since the Flush/Compaction job level may be too coarse with multiple files and block IO level is too granular.
**This PR is for the Write path.** The **Write:** dynamic priority for different state are listed as follows:
| State | Normal | Delayed | Stalled |
| ----- | ------ | ------- | ------- |
| Flush | IO_HIGH | IO_USER | IO_USER |
| Compaction | IO_LOW | IO_USER | IO_USER |
Flush and Compaction writes share the same call path through BlockBaseTableWriter, WritableFileWriter, and FSWritableFile. When a new FSWritableFile object is created, its io_priority_ can be set dynamically based on the state of the WriteController. In WritableFileWriter, before the call sites of FSWritableFile functions, WritableFileWriter::DecideRateLimiterPriority() determines the rate_limiter_priority. The options (IOOptions) argument of FSWritableFile functions will be updated with the rate_limiter_priority.

Summary:
**Context:**
Previous PR https://github.com/facebook/rocksdb/pull/9748, https://github.com/facebook/rocksdb/pull/9073, https://github.com/facebook/rocksdb/pull/8428 added separate flag for each charged memory area. Such API design is not scalable as we charge more and more memory areas. Also, we foresee an opportunity to consolidate this feature with other cache usage related features such as `cache_index_and_filter_blocks` using `CacheEntryRole`.
Therefore we decided to consolidate all these flags with `CacheUsageOptions cache_usage_options` and this PR serves as the first step by consolidating memory-charging related flags.
**Summary:**
- Replaced old API reference with new ones, including making `kCompressionDictionaryBuildingBuffer` opt-out and added a unit test for that
- Added missing db bench/stress test for some memory charging features
- Renamed related test suite to indicate they are under the same theme of memory charging
- Refactored a commonly used mocked cache component in memory charging related tests to reduce code duplication
- Replaced the phrases "memory tracking" / "cache reservation" (other than CacheReservationManager-related ones) with "memory charging" for standard description of this feature.

Summary:
PR https://github.com/facebook/rocksdb/issues/9888 started to enforce the contract of single delete described in https://github.com/facebook/rocksdb/wiki/Single-Delete.
For some of existing use cases, it is desirable to have a transition during which compaction will not fail
if the contract is violated. Therefore, we add a temporary option `enforce_single_del_contracts` to allow
application to opt out from this new strict behavior. Once transition completes, the flag can be set to `true` again.
In a future release, the option will be removed.

Summary:
**Context:**
`BackupEngineRateLimitingTestWithParam.RateLimiting` and `BackupEngineRateLimitingTestWithParam.RateLimitingVerifyBackup` involve creating backup and restoring of a big database with rate-limiting. Using the normal env with a normal clock requires real elapse of time (13702 - 19848 ms/per test). As suggested in https://github.com/facebook/rocksdb/pull/8722#discussion_r703698603, this PR is to speed it up with SpecialEnv (`time_elapse_only_sleep=true`) where its clock accepts fake elapse of time during rate-limiting (100 - 600 ms/per test)
**Summary:**
- Added TEST_ function to set clock of the default rate limiters in backup engine
- Shrunk testdb by 10 times while keeping it big enough for testing
- Renamed some test variables and reorganized some if-else branch for clarity without changing the test

Summary:
These methods allow for more thorough testing of the ObjectRegistry and Customizable infrastructure in a simpler manner. With this change, the Customizable tests can now check what factories are registered and attempt to create each of them in a systematic fashion.
With this change, I think all of the factories registered with the ObjectRegistry/CreateFromString are now tested via the customizable_test classes.
Note that there were a few other minor changes. There was a "posix://*" register with the ObjectRegistry which was missed during the PatternEntry conversion -- these changes found that. The nickname and default names for the FileSystem classes was also inverted.

Summary:
This PR
- since we are testing with disable_wal = true and best_efforts_recovery, we should set column family count to 1, due to the requirement of `ExpectedState` tracking and replaying logic.
- during backup and checkpoint restore, disable best-efforts-recovery. This does not matter now because db_crashtest.py always disables wal when testing best-efforts-recovery. In the future, if we enable wal, then not setting `restore_opitions.best_efforts_recovery` will cause backup db not to recover the WALs, and differ from db (that enables WAL).
- during verification of backup and checkpoint restore, print the key where inconsistency exists between expected state and db.

The pmem-rocksdb-plugin repo contains RocksDB’s plugins for LSM-tree based KV store to fit it on the PMEM by effectively utilize its characteristics. The first two basic plugins are:
1) Providing a filesystem API wrapper to write RocksDB's WAL (Write Ahead Log) files on PMEM to optimize write performance. 2) Using PMEM as secondary cache to optimize read performance.

Summary:
In case of non-TransactionDB and avoid_flush_during_recovery = true, RocksDB won't
flush the data from WAL to L0 for all column families if possible. As a
result, not all column families can increase their log_numbers, and
min_log_number_to_keep won't change.
For transaction DB (.allow_2pc), even with the flush, there may be old WAL files that it must not delete because they can contain data of uncommitted transactions and min_log_number_to_keep won't change.
If we persist a new MANIFEST with
advanced log_numbers for some column families, then during a second
crash after persisting the MANIFEST, RocksDB will see some column
families' log_numbers larger than the corrupted WAL, and the "column family inconsistency" error will be hit, causing recovery to fail.
This PR update unit tests to emulate the errors and tests are failing without a fix.

Summary:
Having all of TMPD, TMPDIR and TEST_TMPDIR as configuration
parameters is confusing. This change simplifies a number of things by
standardizing on TEST_TMPDIR, while still recognizing the old names
also. In detail:
* crash_test.mk also needs to use TEST_TMPDIR for crash test, so put in
shared common.mk (an upgrade of python.mk)
* Always exporting TEST_TMPDIR eliminates the need to propagate TMPD or
export TEST_TMPDIR in selective places.
* Use --tmpdir option to gnu_parallel so that it doesn't need TMPDIR
environment variable
* Remove obsolete parloop and parallel_check Makefile targets
* Remove undefined, unused function ResetTmpDirForDirectIO()

Summary:
ToString() is created as some platform doesn't support std::to_string(). However, we've already used std::to_string() by mistake for 16 months (in db/db_info_dumper.cc). This commit just remove ToString().

Summary:
Previously all fault injection was ignored in release mode. This PR adds it back except for read fault injection (`--read_fault_one_in > 0`) since its dependency (`IGNORE_STATUS_IF_ERROR`) is unavailable in release mode.
Other notable changes include:
- Moved `EnableWriteErrorInjection()` for `--write_fault_one_in > 0` so it's after `DB::Open()` without depending on `SyncPoint`
- Made `--read_fault_one_in > 0` return an error in release mode
- Updated `db_crashtest.py` to always set `--read_fault_one_in=0` in release mode

Test Plan:
```
$ DEBUG_LEVEL=0 make -j24 db_stress
$ DEBUG_LEVEL=0 TEST_TMPDIR=/dev/shm python3 tools/db_crashtest.py blackbox

Summary:
`db_stress` already tracks expected state history to verify prefix-recoverability when `sync_fault_injection` is enabled. This PR enables `sync_fault_injection` in `db_crashtest.py`.
Previously enabling `sync_fault_injection` would cause whole unsynced files to be dropped. This PR adds a more interesting case of losing only the tail of unsynced data by implementing `TestFSWritableFile::RangeSync()` and enabling `{wal_,}bytes_per_sync`.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9947
Test Plan:
- regular blackbox, blackbox --simple
- various commands to stress this new case, such as `TEST_TMPDIR=/dev/shm python3 tools/db_crashtest.py blackbox --max_key=100000 --write_buffer_size=2097152 --avoid_flush_during_recovery=1 --disable_wal=0 --interval=10 --db_write_buffer_size=0 --sync_fault_injection=1 --wal_compression=none --delpercent=0 --delrangepercent=0 --prefixpercent=0 --iterpercent=0 --writepercent=100 --readpercent=0 --wal_bytes_per_sync=131072 --duration=36000 --sync=0 --open_write_fault_one_in=16`
