The existing StandardPolicy that exposed as RBD_LOCK_MODE_EXCLUSIVE
argument to rbd_lock_acquire() disables automatic exclusive lock
transitions with "permanent" semantics: any request to release the lock
causes the peer to error out immediately. Such a lock owner can
perform maintenance operations that are proxied from other peers, but
any write-like I/O issued by other peers will fail with EROFS.
This isn't suitable for use cases where one of the peers wants to
manage exclusive lock manually (i.e. rbd_lock_acquire() is used) but
the lock is acquired only for very short periods of time. The rest of
the time the lock is expected to be held by other peers that stay in
the default "auto" mode (AutomaticPolicy) and run as usual, completely
unconcerned with each other or the manual-mode peer. However, these
peers get acutely aware of the manual-mode peer because when it grabs
the lock with RBD_LOCK_MODE_EXCLUSIVE their I/O gets disrupted: higher
layers translate EROFS into generic EIO, filesystems shut down, etc.
Add a new TransientPolicy exposed as RBD_LOCK_MODE_EXCLUSIVE_TRANSIENT
to allow disabling automatic exclusive lock transitions with semantics
that would cause the other peers to block waiting for the lock to be
released by the manual-mode peer. This is intended to be a low-level
interface -- no attempt to safeguard against potential misuse causing
e.g. indefinite blocking is made.
It's possible to switch between RBD_LOCK_MODE_EXCLUSIVE and
RBD_LOCK_MODE_EXCLUSIVE_TRANSIENT modes of operation both while the
lock is held and after it's released.

In preparation for adding a new TransientPolicy, get rid of the check
implemented in terms of exclusive_lock::Policy::may_auto_request_lock()

In order to effect another change a new image handle would have been
needed which is pretty suboptimal.

doc: Remove sphinxcontrib-seqdiag Python package from RTD builds
This is a proactive PR to avoid breaking docs builds when Setuptools 81
starts to be used in the RTD builds process.
The sphnixcontrib-seqdiag Python package is not compatible with
Setuptools 81 or later due to use of pkg_resources:
https://setuptools.pypa.io/en/latest/pkg_resources.html
Setuptools 81 release should be imminent, with the Python deprecation
warning stating pkg_resources "removal as early as 2025-11-30".
Seqdiag seems to be unmaintained with the latest update at Pypi in
the year 2021 and also no updates to the seqdiag git repo.
There are no seqdiag directives left in the docs after last seqdiags
were removed in PR #52308.
Two other options would exist for fixing the situation (see PR for
discussion) but this seems to be the suitable one.

qa/workunits/rgw: drop netstat usage
The `netstat` is deprecated now in modern Linux and usually
requires an extra package dependency to be installed.
Usually it is `net-tools`, however, for example, opensuse,
`netstat` does not present in it. Thus, let us use `ss` as
an alternative.
When using `netstat -nltp` we get lines like:
'tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 25156/valgrind.bin \ntcp6 0 0 :::443 :::* LISTEN 25156/valgrind.bin \n'

'LISTEN 0 4096 0.0.0.0:443 0.0.0.0:* users:(("memcheck-amd64-",pid=66045,fd=72))'
so we need to filter processes by `memcheck`. However further
parsing code works equivalently as for netstat.

osd/ECUtil: Fix erase_after_ro_offset length calculation and add tests
System test logs showed EC recovery failures with assertion errors when
recovering small objects (smaller than stripe width) in EC pools.
The recovery would fail with "shard_size >= tobj_size" assertions
because shards that should be empty incorrectly contained data.
The primary change in this commit fixes a bug in
shard_extent_map_t::erase_after_ro_offset() where the length
calculation was incorrect:
When ro_offset < ro_start, the incorrect calculation caused data that
should be erased to remain on shards, leading to recovery failures.
Additionally, this commit adds 13 comprehensive unit tests to TestECUtil
that thoroughly exercise erase_after_ro_offset across various edge cases,
including the critical scenario of objects smaller than stripe width where
some shards should remain empty. These tests successfully catch the bug
when it is re-introduced.
Note: The unit tests in this commit were generated with assistance from
an LLM (Large Language Model) and subsequently validated and refined.

osd: Fix issue where it is possible for stats to be recovered incorrectly during merge operations.
To hit the problem, after you take a snapshot, you:
* Perform a write
* Perform a partial write that only involves the primary
* Perform a partial write that only involves a non-primary
* Primary goes down
* Primary comes up
* Primary goes through peering and chooses a non-primary shard as its peering partner
The result of these operations is the stats reporting a size difference equal to the partial write that only involves the primary, as the non-primary is not aware of the clone operation by design and so that is missing update is copied to the osd. This commit prevents it by invalidating the stats in the case where this happens. There will be a future commit to further narrow the set of cases where stats invalidations can happen.
