`get_same_blocks` is a helper to compare two files and return a list of
the blocks that are clones of each other. Its very necessary for block
cloning tests.
Previously it was incorrectly called `unique_blocks`, which is the
_inverse_ of what it does (an early version did list unique blocks; it
was changed but the name was not). So if nothing else, it should be
called `duplicate_blocks`.
But, keeping the details of a clone operation in your head is actually
quite difficult, without the additional overhead of wondering how the
tools work. So I've renamed it to better describe what it does, added a
usage note, and changed it to return block indexes from 0 instead of 1,
to match how L0 blocks are normally counted.

As part of some internal gang block testing within Delphix

The previous patch #14841 appeared to have significant flaw, causing
deadlocks if zl_get_data callback got blocked waiting for TXG sync. I
already handled some of such cases in the original patch, but issue
#14982 shown cases that were impossible to solve in that design.
This patch fixes the problem by postponing log blocks allocation till
the very end, just before the zios issue, leaving nothing blocking after
that point to cause deadlocks. Before that point though any sleeps are
now allowed, not causing sync thread blockage. This require slightly
more complicated lwb state machine to allocate blocks and issue zios
in proper order. But with removal of special early issue workarounds
the new code is much cleaner now, and should even be more efficient.
Since this patch uses null zios between write, I've found that null
zios do not wait for logical children ready status in zio_ready(),
that makes parent write to proceed prematurely, producing incorrect
log blocks. Added ZIO_CHILD_LOGICAL_BIT to zio_wait_for_children()
fixes it.

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.

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

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

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.
