Keeping the spl/zfs module split, libzpool is the zfs module for
userspace. Headers and functions specific to it belong there.

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.

We need to specifically use the FX_XFLAG_* macros in zpl_ioctl_*attr()
codepaths, and the FS_*_FL macros in the zpl_ioctl_*flags() codepaths.
The earlier code just assumes the FS_*_FL macros for both codepaths.
The 6.17 kernel add a bitmask check in copy_fsxattr_from_user() that
exposed this error via failing 'projectquota' ZTS tests.

Closes#17708
A single slow responding disk can affect the overall read
performance of a raidz group. When a raidz child disk is
determined to be a persistent slow outlier, then have it
sit out during reads for a period of time. The raidz group
can use parity to reconstruct the data that was skipped.
Each time a slow disk is placed into a sit out period, its
`vdev_stat.vs_slow_ios count` is incremented and a zevent
class `ereport.fs.zfs.delay` is posted.
The length of the sit out period can be changed using the
`raid_read_sit_out_secs` module parameter. Setting it to
zero disables slow outlier detection.

This changes zil_commit() to have an int return, and updates all callers
to check it. There are no corresponding internal changes yet; it will
always return 0.
Since zil_commit() is an indication that the caller _really_ wants the
associated data to be durability stored, I've annotated it with the
__warn_unused_result__ compiler attribute (via __must_check), to emit a
warning if it's ever ussd without doing something with the return code.
I hope this will mean we never misuse it in the future.

These are all cases where we initialise or update a variable, and then
never use it. None of them particularly matter, as the compiler should
optimise them all away during dead store elimination, but some static
analysers complain about them and they are extra work for casual readers
to follow, so worth removing.

5b9e695 added specific userspace versions of abd_os.h and abd_impl_os.h
for libzpool. However, abd.h and abd_impl.h, which include them, are
packaged with libzfs, so other programs building against libzfs can
fail to build, either because the headers aren't installed, or because
they aren't on any standard include path.
So, move abd_os.h and abd_impl_os.h to libspl, where they we will be
installed alongside abd.h and abd_impl.h in a known path.

This is the sort of code that we get right once and never look at again.
Anyone reading this code is already likely in the middle of a debugging
nightmare, and then they have a wall of manual string construction and
an unfamiliar and idiosyncratic library to deal with. So, comment the
whole thing to try to make it clear what's going on.
In pursuit of the above, I've added return checks to some of the
libunwind calls, fixed the frame loop to not skip the "top" frame
(however unseful it may be), and fix a couple of calls to
spl_bt_u64_to_hex_str() which requested 18 digits instead of 16.
