Summary:
To stop spamming our warning logs with normal behavior.
Also fix comment on `DisableFileDeletions()`.
In response to https://github.com/facebook/rocksdb/issues/12001 I've indicated my objection to granting legitimacy to force=true, but I'm not addressing that here and now. In short, the user shouldn't be asked to think about whether they want to use the *wrong* behavior. ;)

Summary:
Provide support for FSBuffer for point lookups
It also add support for compaction and scan reads that goes through BlockFetcher when readahead/prefetching is not enabled.
Some of the compaction/Scan reads goes through FilePrefetchBuffer and some through BlockFetcher. This PR add support to use underlying file system scratch buffer for reads that go through BlockFetcher as for FilePrefetch reads, design is complicated to support this feature.
Design - In order to use underlying FileSystem provided scratch for Reads, it uses MultiRead with 1 request instead of Read API which required API change.

Test Plan: Stress test using underlying file system scratch buffer internally.

Summary:
For the user defined timestamps in memtable only feature, some special handling for range deletion blocks are needed since both the key (start_key) and the value (end_key) of a range tombstone can contain user-defined timestamps. Handling for the key is taken care of in the same way as the other data blocks in the block based table. This PR adds the special handling needed for the value (end_key) part. This includes:
1) On the write path, when L0 SST files are first created from flush, user-defined timestamps are removed from an end key of a range tombstone. There are places where it's logically removed (replaced with a min timestamp) because there is still logic with the running comparator that expects a user key that contains timestamp. And in the block based builder, it is eventually physically removed before persisted in a block.
2) On the read path, when range deletion block is being read, we artificially pad a min timestamp to the end key of a range tombstone in `BlockBasedTableReader`.
3) For file boundary `FileMetaData.largest`, we artificially pad a max timestamp to it if it contains a range deletion sentinel. Anytime when range deletion end_key is used to update file boundaries, it's using max timestamp instead of the range tombstone's actual timestamp to mark it as an exclusive end. d69628e6ce/db/dbformat.h (L923-L935)
This max timestamp is removed when in memory `FileMetaData.largest` is persisted into Manifest, we pad it back when it's read from Manifest while handling related `VersionEdit` in `VersionEditHandler`.

Summary:
While working on Meta's internal test triaging process, I found that `db_crashtest.py` was printing out `stdout` and `stderr` altogether. Adding an option to print `stderr` separately so that it's easy to extract only `stderr` from the test run.
`print_stderr_separately` is introduced as an optional parameter with default value `False` to keep the existing behavior as is (except a few minor changes).
Minor changes to the existing behavior
- We no longer print `stderr has error message:` and `***` prefix to each line. We simply print `stderr:` before printing `stderr` if stderr is printed in stdout and print `stderr` as is.
- We no longer print `times error occurred in output is ...` which doesn't appear to have any values

Summary:
In C++, `extern` is redundant in a number of cases:
* "Global" function declarations and definitions
* "Global" variable definitions when already declared `extern`
For consistency and simplicity, I've removed these in code that *we own*. In a couple of cases, I removed obsolete declarations, and for MagicNumber constants, I have consolidated the declarations into a header file (format.h)
as standard best practice would prescribe.

Summary:
After https://github.com/facebook/rocksdb/issues/12253 this function has crashed in the crash test, in its call to `std::copy`. I haven't reproduced the crash directly, but `std::copy` probably has undefined behavior if the starting iterator is after the ending iterator, which was possible. I've fixed the logic to deal with that case and to add an assertion to check that precondition of `std::copy` (which appears can be unchecked by `std::copy` itself even with UBSAN+ASAN).
Also added some unit tests etc. that were unfinished for https://github.com/facebook/rocksdb/issues/12253, and slightly tweak SeqnoToTimeMapping::EnforceMaxTimeSpan handling of zero time span case.
This is intended for patching 8.11.

Received signal 11 (Segmentation fault: 11)
https://github.com/facebook/rocksdb/issues/1 rocksdb::MockSystemClock::InstallTimedWaitFixCallback()::$_0::operator()(void*) const (in seqno_time_test) (mock_time_env.cc:29)
https://github.com/facebook/rocksdb/issues/2 decltype(std::declval<rocksdb::MockSystemClock::InstallTimedWaitFixCallback()::$_0&>()(std::declval<void*>())) std::__1::__invoke[abi:v15006]<rocksdb::MockSystemClock::InstallTimedWaitFixCallback()::$_0&, void*>(rocksdb::MockSystemClock::InstallTimedWait ixCallback()::$_0&, void*&&) (in seqno_time_test) (invoke.h:394)
...
```
This is presumably because the std::function from the lambda only saves a copy of the SeqnoTimeTest* this pointer, which doesn't prevent it from being reclaimed on parallel shutdown. If we instead save a copy of the `std::shared_ptr<MockSystemClock>` in the std::function, this should prevent the crash. (Note that in `SyncPoint::Data::Process()` copies the std::function before releasing the mutex for calling the callback.)

Summary:
This PR adds estimated pending compaction bytes in two places:
- The "Level summary", which is printed to the info LOG after every flush or compaction
- The "rocksdb.cfstats" property, which is printed to the info LOG periodically according to `stats_dump_period_sec`
Pull Request resolved: https://github.com/facebook/rocksdb/pull/12267
Test Plan:
Ran `./db_bench -benchmarks=filluniquerandom -stats_dump_period_sec=1 -statistics=true -write_buffer_size=524288` and looked at the LOG.
