The extra inclusion via xvattr.h appears to upset the linter in CI. I'm
not entirely sure what its complaint is, but removing sys/string.h
entirely is not quite possible yet, and include guards are rarely a bad
idea, so this will do.

The zfs_tunable_* functions are a public interface which are
part of the internal libspl convenience library. They should
be hidden to prevent an unnecessary ABI change in installed
libraries which link against libspl (e.g. libzfs_core, libuutil).
We do already leak long standing libspl symbols. This commit is
solely intended to prevent leaking these new ones until this is
properly sorted out.

This is useful as debugging support, as it lets namespace lock
operations be traced directly. It will also be useful for future work to
reduce the use of spa_namespace_lock, traditionally a source of

Closes#17906
We have infinite loop and on certain condition, we exit this loop
and thread with pthread_exit(). But also after this loop,
we have a code to perform pthread_cleanup_pop() and return from the
thread.
The problem is that modern compilers are able to recognize that we
actually never get to the statements after loop and therefore
it is dead code there.
I think, instead of pthread_exit(), it is better to break out of loop
and let the last statements to work as intended. This is because
we do need to keep pthread_cleanup_pop() anyhow. Of course,
it is matter of taste if we want to use return or pthread_exit as very
last statement in this function.

We need to specifically use the FX_XFLAG_* macros in zpl_ioctl_*attr()

The earlier code just assumes the FS_*_FL macros for both codepaths.

A small uplift of the cmn_err() and panic() calls in userspace:
- remove the suppression on CE_NOTE. We have very few of these calls in
a standard build, it's convenient for "print debugging".
- make prefixes clear and consistent.
- add LIBZPOOL_PANIC_STOP environment variable to send SIGSTOP to the
process group on a panic, rather than abort(), so all threads remain
alive for inspection.

In "all pools" mode, pool_iter_refresh() will call zpool_iter(), which
will call zpool_refresh_stats() before calling add_pool(). If we already
have the pool, this is a different handle, so we just release it and
return. Back in pool_iter_refresh(), we then call zpool_stats_refresh()
again for our handle on the same pool.
All together, this means we're doing two ZFS_IOC_POOL_STATS calls into
the kernel for every pool in the system. This isn't wrong, but it does
double the pressure on global locks.
Instead, we add a new function zpool_refresh_stats_from_handle() that
simply copies the pool config and state from one handle to another, and
use it to update our handle before we release it in add_pool(), so we
only have one call per pool per interval.
