Summary:
This diff is a first step towards an iterator based interface for the
SearchRadial method which replaces a vector of GeoObjects with an
iterator for GeoObjects. This diff works by just wrapping the iterator
for the encapsulated vector of GeoObjects. A future diff could extend
this approach by defining an interator in terms of the underlying
iteration in SearchRadial which would then remove the need to have
an in-memory representation for all the matching GeoObjects.
Fixes T8421387
Test Plan:
The existing tests have been modified to work with the new
interface.

Summary:
MyRocks reported some perfomance issues when inserting many keys into a transaction due to the cost of inserting new keys into WriteBatchWithIndex. Frequently, they don't even need the keys to be indexed as they don't need to read them back. DisableIndexing() can be used to avoid the cost of indexing.
I also plan on eventually investigating if we can improve WriteBatchWithIndex performance. But even if we improved the perf here, it is still beneficial to be able to disable the indexing all together for large transactions.

Summary:
WriteBatchWithIndex::GetFromBatchAndDB only works correctly for overwrite_key=false. Transactions use overwrite_key=true (since WriteBatchWithIndex::GetIteratorWithBase only works when overwrite_key=true). So currently, Transactions could return incorrectly merged results when calling Get/GetForUpdate().
Until a permanent fix can be put in place, Transaction::Get[ForUpdate] and WriteBatchWithIndex::GetFromBatch[AndDB] will now return MergeInProgress if the most recent write to a key in the batch is a Merge.

Summary:
This patch fixes#7460559. It introduces SingleDelete as a new database
operation. This operation can be used to delete keys that were never
overwritten (no put following another put of the same key). If an overwritten
key is single deleted the behavior is undefined. Single deletion of a
non-existent key has no effect but multiple consecutive single deletions are
not allowed (see limitations).
In contrast to the conventional Delete() operation, the deletion entry is
removed along with the value when the two are lined up in a compaction. Note:
The semantics are similar to @igor's prototype that allowed to have this
behavior on the granularity of a column family (
https://reviews.facebook.net/D42093 ). This new patch, however, is more
aggressive when it comes to removing tombstones: It removes the SingleDelete
together with the value whenever there is no snapshot between them while the
older patch only did this when the sequence number of the deletion was older
than the earliest snapshot.
Most of the complex additions are in the Compaction Iterator, all other changes
should be relatively straightforward. The patch also includes basic support for
single deletions in db_stress and db_bench.
Limitations:
- Not compatible with cuckoo hash tables
- Single deletions cannot be used in combination with merges and normal
deletions on the same key (other keys are not affected by this)
- Consecutive single deletions are currently not allowed (and older version of
this patch supported this so it could be resurrected if needed)

Summary:
ROCKSDB_WARNING is only defined if either ROCKSDB_PLATFORM_POSIX or OS_WIN is defined. This works well for building rocksdb with its own build scripts. But this won't work when an outside project(like mongodb) doesn't define ROCKSDB_PLATFORM_POSIX.
This fix defines ROCKSDB_WARNING for all platforms. No idea if its defined correctly on non-posix,non-windows platforms but this is no worse that the current situation where this macro is missing on unexpected platforms.
This fix should hopefully fix anyone whose build broke now that we've switched from using #warning to Pragma (to support windows). Unfortunately, while mongo-rocks compiles, it ignores the Pragma and doesn't print a warning. I have not been able to figure out a way to implement this portably on all platforms.
Of course, an alternate solution would be to just get rid of ROCKSDB_WARNING and live with include file redirects indefinitely. Thoughts?

Couple of changes here:
* NewBackupEngine() and NewReadOnlyBackupEngine() are now removed. They were deprecated since RocksDB 3.8. Changing these to new functions should be pretty straight-forward. As a followup, I'll fix all fbcode callsights
* Instead of initializing backup engine in the constructor, we initialize it in a separate function now. That way, we can catch all errors and return appropriate status code.
* We catch all errors during initializations and return them to the client properly.
* Added new tests to backupable_db_test, to make sure that we can't open BackupEngine when there are Env errors.
* Transitioned backupable_db_test to use BackupEngine rather than BackupableDB. From the two available APIs, judging by the current use-cases, it looks like BackupEngine API won. It's much more flexible since it doesn't require StackableDB.
