The generic_file_splice_read function was removed in Linux 6.5 in favor
of filemap_splice_read. Add an autoconf test for filemap_splice_read and
use it if it is found as the handler for .splice_read in the
file_operations struct. Additionally, ITER_PIPE was removed in 6.5. This
change removes the ITER_* macros that OpenZFS doesn't use from being
tested in config/kernel-vfs-iov_iter.m4. The removal of ITER_PIPE was
causing the test to fail, which also affected the code responsible for
setting the .splice_read handler, above. That behavior caused run-time
panics on Linux 6.5.

When compiling a kernel with bcachefs and zfs,
the two macros will collide, making it impossible
to have both filesystems.
It is sufficient to just undefine the macro before calling it.
On why this should be in ZFS rather than bcachefs, currently,
bcachefs is not a in-tree filesystem, but,
it has a reasonably high chance of getting included soon.
This avoids the breakage in ZFS early,
this patch may be distributed downstream in NixOS

- Split dmu_prefetch_dnode() from dmu_prefetch() into a separate
function. It is quite inconvenient to read the code where len = 0
means dnode prefetch instead indirect/data prefetch. One function
doing both has no benefits, since the code paths are independent.
- Improve dmu_prefetch() handling of long block ranges. Instead
of limiting L0 data length to prefetch for to dmu_prefetch_max,
make dmu_prefetch_max limit the actual amount of prefetch at the
specified level, and, if there is more, prefetch all the rest at
higher indirection level. It should improve random access times
within the prefetched range of any length, reducing importance of
specific dmu_prefetch_max value.

When the vdev properties features was merged an extra check
was added in `spa_vdev_remove_top_check()` which checked
whether the vdev that we want to remove is already being
removed and if so return an EALREADY error.
```
static int
spa_vdev_remove_top_check(vdev_t *vd)
{
... <snip> ...
/*
* This device is already being removed
*/
if (vd->vdev_removing)
return (SET_ERROR(EALREADY));
```
Before that change we'd still fail with an error but it
was a more generic one - here is the check that failed
later in the same function:
```
/*
* There can not be a removal in progress.
*/
if (spa->spa_removing_phys.sr_state == DSS_SCANNING)
return (SET_ERROR(EBUSY));
```
Changing the error code returned from that function changed
the behavior of the removal's library interface exposed to
the userland - `spa_vdev_remove()` now returns `EZFS_UNKNOWN`
instead of `EZFS_EBUSY` that was returning before.
This patch adds logic to make `spa_vdev_remove()` mindful
of the new EALREADY code and propagating `EZFS_EBUSY`
reverting to the previously established semantics of that
function.

Before Linux 5.3, the filesystem's copy_file_range handler had to signal
back to the kernel that we can't fulfill the request and it should
fallback to a content copy. This is done by returning -EOPNOTSUPP.
This commit converts the EXDEV return from zfs_clone_range to
EOPNOTSUPP, to force the kernel to fallback for all the valid reasons it
might be unable to clone. Without it the copy_file_range() syscall will
return EXDEV to userspace, breaking its semantics.
Add test for copy_file_range fallbacks. copy_file_range should always
fallback to a content copy whenever ZFS can't service the request with

Fastwrite was introduced many years ago to improve ZIL writes spread
between multiple top-level vdevs by tracking number of allocated but
not written blocks and choosing vdev with smaller count. It suposed
to reduce ZIL knowledge about allocation, but actually made ZIL to
even more actively report allocation code about the allocations,
complicating both ZIL and metaslabs code.
On top of that, it seems ZIO_FLAG_FASTWRITE setting in dmu_sync()
was lost many years ago, that was one of the declared benefits. Plus
introduction of embedded log metaslab class solved another problem
with allocation rotor accounting both normal and log allocations,
since in most cases those are now in different metaslab classes.
After all that, I'd prefer to simplify already too complicated ZIL,
ZIO and metaslab code if the benefit of complexity is not obvious.

Block cloning introduced a new state transition from DB_NOFILL to
DB_READ. This occurs when a block is cloned and then read on the
current txg.
In this case, the clone will move the dbuf to DB_NOFILL, and then the
read will be issued for the overidden block pointer. If that read is
still outstanding when it comes time to write, the dbuf will be in
DB_READ, which is not handled by the checks in dbuf_sync_leaf, thus
tripping the assertions.
This updates those checks to allow DB_READ as a valid state iff the
dirty record is for a BRT write and there is a override block pointer.
This is a safe situation because the block already exists, so there's
nothing that could change from underneath the read.
