Pull all of the internal debug infrastructure up in to the zfs
code to clean up the layering. Remove all the dodgy usage of
SET_ERROR and DTRACE_PROBE from the spl. Luckily it was
lightly used in the spl layer so we're not losing much.

These are kind-of compiler attribute placeholders, so go here with the
others for now.

sys/debug.h is not really the right place for them, but we already have
some there for libspl, so it is at least convenient.

Closes#17861
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.

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

Closes#17861
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.
