Summary:
Fix memory corruption error in scans if async_io is enabled. Memory corruption happened if data is overlapping between two buffers. If there is IOError while reading the data, it leads to empty buffer and other buffer already in progress of async read goes again for reading causing the error.
Fix: Added check to abort IO in second buffer if curr_ got empty.
This PR also fixes db_stress failures which happened when buffers are not aligned.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/10890
Test Plan:
- Ran make crash_test -j32 with async_io enabled.
- Ran benchmarks to make sure there is no regression.

Summary:
This PR implements the originally disabled `Merge()` APIs when user-defined timestamp is enabled.
Simplest usage:
```cpp
// assume string append merge op is used with '.' as delimiter.
// ts1 < ts2
db->Put(WriteOptions(), "key", ts1, "v0");
db->Merge(WriteOptions(), "key", ts2, "1");
ReadOptions ro;
ro.timestamp = &ts2;
db->Get(ro, "key", &value);
ASSERT_EQ("v0.1", value);
```
Some code comments are added for clarity.
Note: support for timestamp in `DB::GetMergeOperands()` will be done in a follow-up PR.

Summary:
The motivation and benefit of current behavior of passing `LockInfo&&` as argument to AcquireLocked() and AcquireWithTimeout() is not clear to me. Furthermore, in AcquireWithTimeout(), we access members of `LockInfo&&` after it is passed to AcquireLocked() as rvalue ref. In addition, we may call `AcquireLocked()` with `std::move(lock_info)` multiple times.
This leads to linter warning of use-after-move. If future implementation of AcquireLocked() does something like moving-construct a new `LockedInfo` using the passed-in `LockInfo&&`, then the caller cannot use it because `LockInfo` has a member of type `autovector`.

Summary:
The PR fixes the handling of `Merge`s in `GetEntity`. Note that `Merge` is not yet
supported for wide-column entities written using `PutEntity`; this change is
about returning correct (i.e. consistent with `Get`) results in cases like when the
base value is a plain old key-value written using `Put` or when there is no real base
value because we hit either a tombstone or the beginning of history.
Implementation-wise, the patch introduces a new wrapper around the existing
`MergeHelper::TimedFullMerge` that can store the merge result in either a string
(for the purposes of `Get`) or a `PinnableWideColumns` instance (for `GetEntity`).

Summary:
Right now in MergingIterator, for each range tombstone start and end key, we pop one end from heap and push the other end into the heap. This involves extra downheap and upheap cost. In the likely cases when a range tombstone iterator emits relatively adjacent keys, these keys should have similar order within all keys in the heap. This can happen when there is a burst of consecutive range tombstones, and most of the keys covered by them are dropped already. This PR uses `replace_top()` when inserting new range tombstone keys, which is more efficient in these common cases.

Summary:
Resolves see https://github.com/facebook/rocksdb/issues/9006
Fixes 2 related issues with JNI local references in the RocksJava API.
1. Some instances of RocksJava API JNI code appear to have misunderstood the reason for `JNIEnv->EnsureLocalCapacity()` and are carrying out bogus checks which happen to fail with some larger parameter values (many column families in a single call, very long key names or values). Remove these checks and add some regression tests for the previous failures.
2. The helper for Transaction multiGet operations (`multiGet()`, `multiGetForUpdate()`,...) is limited in the number of keys it can `get()` for because it requires a corresponding number of live local references. Refactor the helper slightly, copying out the key contents within a loop so that the references don't have to exist at the same time.

Summary:
Currently, the name of `block_cache_trace_analyzer_tool` in `CMakeLists.txt` is somewhat confusing.
## Makefile
The same thing in Makefile is called `block_cache_trace_analyzer`.
```c++
block_cache_trace_analyzer: $(OBJ_DIR)/tools/block_cache_analyzer/block_cache_trace_analyzer_tool.o $(ANALYZE_OBJECTS) $(TOOLS_LIBRARY) $(LIBRARY)
$(AM_LINK)
```
## RocksDB Wiki
Also, in the [Block-cache-analysis-and-simulation-tools](https://github.com/facebook/rocksdb/wiki/Block-cache-analysis-and-simulation-tools#quick-start) of RocksDB Wiki, it is called `block_cache_trace_analyzer` too.

Therefore, I think maybe it's better to rename `block_cache_trace_analyzer_tool` to `block_cache_trace_analyzer` in `CMakeLists.txt`.

Summary:
FragmentedRangeTombstoneList has a member variable `seq_set_` that contains the sequence numbers of all range tombstones in a set. The set is constructed in `FragmentTombstones()` and is used only in `FragmentedRangeTombstoneList::ContainsRange()` which only happens during compaction. This PR moves the initialization of `seq_set_` to `FragmentedRangeTombstoneList::ContainsRange()`. This should speed up `FragmentTombstones()` when the range tombstone list is used for read/scan requests. Microbench shows the speed improvement to be ~45%.

Test Plan:
- Existing tests and stress test: `python3 tools/db_crashtest.py whitebox --simple --verify_iterator_with_expected_state_one_in=5`.

- For this path, we simply reuse the fix in `FindIntraL0Compaction` https://github.com/facebook/rocksdb/pull/5958/files#diff-c261f77d6dd2134333c4a955c311cf4a196a08d3c2bb6ce24fd6801407877c89R56
- This path was not stress-tested at all. Therefore we covered `fifo.allow_compaction` in stress test to surface the overlapping seqno issue we are fixing here.
- [FIFOCompactionPicker::PickCompactionToWarm](https://github.com/facebook/rocksdb/blob/7.6.fb/db/compaction/compaction_picker_fifo.cc#L313) when `compaction_options_fifo.age_for_warm > 0`
- For this path, we simply replicate the idea in https://github.com/facebook/rocksdb/pull/5958#issue-511150930 and skip files of largest seqno greater than `earliest_mem_seqno`
- This path was not stress-tested at all. However covering `age_for_warm` option worths a separate PR to deal with db stress compatibility. Therefore we manually tested this path for this PR
- [FIFOCompactionPicker::CompactRange](https://github.com/facebook/rocksdb/blob/7.6.fb/db/compaction/compaction_picker_fifo.cc#L365) that ends up picking one of the above two compactions
- [CompactionPicker::CompactFiles](https://github.com/facebook/rocksdb/blob/7.6.fb/db/compaction/compaction_picker.cc#L378)
- Since `SanitizeCompactionInputFiles()` will be called [before](https://github.com/facebook/rocksdb/blob/7.6.fb/db/compaction/compaction_picker.h#L111-L113) `CompactionPicker::CompactFiles` , we simply replicate the idea in https://github.com/facebook/rocksdb/pull/5958#issue-511150930 in `SanitizeCompactionInputFiles()`. To simplify implementation, we return `Stats::Abort()` on encountering seqno-overlapped file when doing compaction to L0 instead of skipping the file and proceed with the compaction.
Some additional clean-up included in this PR:
- Renamed `earliest_memtable_seqno` to `earliest_mem_seqno` for consistent naming
- Added comment about `earliest_memtable_seqno` in related APIs
- Made parameter `earliest_memtable_seqno` constant and required
Pull Request resolved: https://github.com/facebook/rocksdb/pull/10777
Test Plan:
- make check
- New unit test `TEST_P(DBCompactionTestFIFOCheckConsistencyWithParam, FlushAfterIntraL0CompactionWithIngestedFile)`corresponding to the above 4 cases, which will fail accordingly without the fix
- Regular CI stress run on this PR + stress test with aggressive value https://github.com/facebook/rocksdb/pull/10761 and on FIFO compaction only

Summary:
`#include "db/range_tombstone_fragmenter.h"` seems to break some internal test for 7.8 release. I'm removing it from sst_file_reader.h for now to unblock release. This should be fine as it is only used in a unit test for DeleteRange with timestamp. In addition, it does not seem to be useful to support delete range for sst file writer, since the range tombstone won't cover any key (its sequence number is 0). So maybe we can remove it in the future.

Summary:
Right now UserComparatorWrapper is a Customizable object, although it is not, which introduces some intialization overhead for the object. In some benchmarks, it shows up in CPU profiling. Make it not configurable by defining most functions needed by UserComparatorWrapper to an interface and implement the interface.
