Summary:
When using `PRIu64` type of printf specifier, current code base does the following:
```
#ifndef __STDC_FORMAT_MACROS
#define __STDC_FORMAT_MACROS
#endif
#include <inttypes.h>
```
However, this can be simplified to
```
#include <cinttypes>
```
as long as flag `-std=c++11` is used.
This should solve issues like https://github.com/facebook/rocksdb/issues/5159

Summary:
When the --reopen option is non-zero, the DB is reopened after every ops_per_thread/(reopen+1) ops, with the check being done after every op. With MultiGet, we might do multiple ops in one iteration, which broke the logic that checked when to synchronize among the threads and reopen the DB. This PR fixes that logic.

Summary:
This PR has two fixes for crash test failures -
1. Fix a bug in TestMultiGet() in db_stress that was passing list of key to MultiGet() in the wrong order, thus ensuring that actual values don't match expected values
2. Remove an incorrect assertion in FilePickerMultiGet::GetNextFileInLevelWithKeys() that checks that files in a level are in sorted order. This is not true with MultiGet(), especially if there are duplicate keys and we may have to go back one file for the next key. Furthermore, this assertion makes more sense when a new version is created, rather than at lookup time

* in db_stress, the key vector for MultiGet is created using `emplace_back` which could potentially invalidates references to the underlying storage (vector<string>) due to auto resizing. Fix by calling reserve in advance.
* Similar issue in construction of GetContext autovector in version_set.cc

Summary:
At least one of the meta-block loading functions (`ReadRangeDelBlock`)
uses the same block reading function (`NewDataBlockIterator`) as data
block reads, which means it uses the dictionary handle. However, the
dictionary handle was uninitialized while reading meta-blocks, causing
readers to receive an error. This situation was only noticed when
`cache_index_and_filter_blocks=true`.
This PR initializes the handle to null while reading meta-blocks to
prevent the error. It also adds support to `db_stress` /
`db_crashtest.py` for `cache_index_and_filter_blocks`.
Fixes#5263.

We can remove the assersion because we do not perform verification in
AtomicFlushStressTest::TestCheckpoint for similar reasons to TestGet, TestPut,
etc.
Therefore, we override TestCheckpoint in AtomicFlushStressTest so that the
assertion `rand_column_families.size() == rand_keys.size()' is removed, and we
do not verify the DB in this function.

more to scan.
Second, an underlying error has occurred, causing `status()` to be !ok.

We already exercised backup functionality in `db_stress` according to the `-backup_one_in` flag. This PR verifies the backup can be restored/opened and sanity checks a few keys. Changes in this PR:
- Extracted existing backup-related logic to a helper function, `TestBackupRestore`
- Added restore logic, which targets a hidden directory named "./.restore\<thread number\>", similar to how backups target hidden directories named "./.backup\<thread number\>".
- After restore, check the existence/non-existence of a few keys.
- With this PR, backup is no longer compatible with clearing column families.
- Also included unrelated fixes to set `ReadOptions::total_order_seek=true` when using `-compare_full_db_state_snapshot`

Summary:
Originally, the manual flush calls in db_stress flushes only a single column
family, which is not sufficient when atomic flush is enabled.
With atomic flush, we should call `Flush(flush_opts, cfhs)` to better test this
new feature. Specifically, we manuall flush all column families so that
database verification is easier.

Summary:
TransactionOptions::skip_concurrency_control allows pessimistic transactions to skip the overhead of concurrency control. This could be as an optimization if the application knows that the transaction would not have any conflict with concurrent transactions. It is currently used during recovery assuming (i) application guarantees no conflict between prepared transactions in the WAL (ii) application guarantees that recovered transactions will be rolled back/commit before new transactions start.

This is a followup to #4311. Checking `!RangeDelAggregator::IsEmpty()` before opening a dedicated range tombstone SST did not properly prevent empty SSTs from being generated. That's because it relies on `CollapsedRangeDelMap::Size`, which had an underflow bug when the map was empty. This PR fixes that underflow bug.
Also fixed an uninitialized variable in db_stress.

Summary:
The API comment on `OnTableFileCreationStarted` (b6280d01f9/include/rocksdb/listener.h (L331-L333)) led users to believe a call to `OnTableFileCreationStarted` will always be matched with a call to `OnTableFileCreated`. However, we were skipping the `OnTableFileCreated` call in one case: no error happens but also no file is generated since there's no data.
This PR adds the call to `OnTableFileCreated` for that case. The filename will be "(nil)" and the size will be zero.

Summary:
RocksDB used to store global_seqno in external SST files written by
SstFileWriter. During file ingestion, RocksDB uses `pwrite` to update the
`global_seqno`. Since random write is not supported in some non-POSIX compliant
file systems, external SST file ingestion is not supported on these file
systems. To address this limitation, we no longer update `global_seqno` during
file ingestion. Later RocksDB uses the MANIFEST and other information in table
properties to deduce global seqno for externally-ingested SST files.

Once per `ingest_external_file_one_in` operations, uses SstFileWriter to create a file containing `ingest_external_file_width` consecutive keys. The file is named containing the thread ID to avoid clashes. The file is then added to the DB using `IngestExternalFile`.
We can't enable it by default in crash test because `nooverwritepercent` and `test_batches_snapshot` both must be zero for the DB's whole lifetime. Perhaps we should setup a separate test with that config as range deletion also requires it.
