[PATCH pve-ceph] backport fix for BlueFS space leak on close

[Kefu Chai]

BlueFS reserves space for each RocksDB file. Since 20.1.0, a tentacle
RC, it does not free the reserved but unused part when the file is
closed (PR #62224). That space stays in use until compaction deletes
the file.

For the user this means an OSD uses more space than its data needs. In
bad cases a 70MB file holds only a few kB of data. Clusters without
RocksDB sharding are affected most. If DB and block are on the same
device, the free space of a pool goes up and down, while the stored
data does not change (https://tracker.ceph.com/issues/76256).

The fix is merged for main (https://github.com/ceph/ceph/pull/71479),
but its tentacle backport (https://github.com/ceph/ceph/pull/71855) is
still open, so no point release has it yet. Pick up its three commits
(most recent last):

  * 8e68cb4b9bf0941fe3a2f20678844a0721de9904
  * 21c357d88278eceb0beb9c69c837ad68517e2df4
  * efe2e8d1bf0be327118da6e9e62f6132e6335c9e

They are the fix, a small cleanup asked for in review, and a missing
file lock in BlueFS::truncate()
(https://tracker.ceph.com/issues/80188). They drop out on the next
rebase.

+Subject: [PATCH] os/bluestore: Re-introduce truncation in
+ `BlueRocksWritableFile.Close()`
+
+`rocksdb::WritableFile` assumes that whatever was allocated using `Allocate()`, and was not actually written to, is released when the file is closed (cf. `PosixWritableFile::Close()`). This used to work up to PR #62224 (released in 20.1.0, a tentacle RC), which removed the truncation from `close` and it assumed that `truncate` is called.
+
+This PR adds the truncation back to `BlueRocksWritableFile::Close()`. We cannot bring back the exact pre-62224 code, as it relies on `h->pos`. Instead we flush the file and use `fnode.size`, which contains the on-disk size, including the envelope.
+
+This should fix https://tracker.ceph.com/issues/76256.
+
+I'm not sure why this issue excessively affected clusters with no sharding. From the logs attached to the issue, in the non-sharded case there are many files with only a few kB payload in a 70MB file; in the sharded case the unreleased file tails still exist, but are much smaller.
+
+The new test case unit-tests the new `truncate_unused_allocations()` method, overall correctness of BlueFS operation is covered by other tests already. We also delete `BlueStoreWritableFile::UseDirectIO()`, as it is unused (it doesn't override superclass method).
