db: VersionEdit can understand the format introduced in PR 3488.
RocksDB's PR 3488 introduced a new format of `VersionEdit`
encoding which is not understandable for older versions.
Thus, the change broke forward compatibility and has been
reverted in PR 3762. Later, PR 3765 reiterated the concept
but in a way that does not provide compatibility with the very
short-living format of PR 3488.
This change tries to address the issue of accessing DBs
in format of 3488 by ignoring the special entries.

Allow range deletions in `*TransactionDB` only when safe (#7929)
Summary:
Explicitly reject all range deletions on `TransactionDB` or `OptimisticTransactionDB`, except when the user provides sufficient promises that allow us to proceed safely. The necessary promises are described in the API doc for `TransactionDB::DeleteRange()`. There is currently no way to provide enough promises to make it safe in `OptimisticTransactionDB`.

workaround race conditions during `PeriodicWorkScheduler` registration (#7888)
Summary:
This provides a workaround for two race conditions that will be fixed in
a more sophisticated way later. This PR:
(1) Makes the client serialize calls to `Timer::Start()` and `Timer::Shutdown()` (see https://github.com/facebook/rocksdb/issues/7711). The long-term fix will be to make those functions thread-safe.
(2) Makes `PeriodicWorkScheduler` atomically add/cancel work together with starting/shutting down its `Timer`. The long-term fix will be for `Timer` API to offer more specialized APIs so the client will not need to synchronize.

Attempt to fix build errors around missing compression library includes (#7803)
Summary:
This fixes an issue introduced in https://github.com/facebook/rocksdb/pull/7769 that caused many errors about missing compression libraries to be displayed during compilation, although compilation actually succeeded. This PR fixes the compilation so the compression libraries are only introduced where strictly needed.
It likely needs to be merged into the same branches as https://github.com/facebook/rocksdb/pull/7769 which I think are:
1. master
2. 6.15.fb
3. 6.16.fb
