Consider the test to be a success as long as the initializing pattern
is found at least once per metaslab. This indicates that at least
part of the free space was initialized. Ideally we'd check that the
pattern was written to all free space but that's much trickier so this
check is a reasonable compromise.
Using a here-string to feed the loop in this test causes an empty
string to still trigger the loop so we miss the `spacemaps=0` case.
Pipe into the loop instead.
While here, we can use `zpool wait -t initialize $TESTPOOL` to wait for
the pool to initialize.

The space in special devices is not included in spa_dspace (or
dsl_pool_adjustedsize(), or the zfs `available` property). Therefore
there is always at least as much free space in the normal class, as
there is allocated in the special class(es). And therefore, there is
always enough free space to remove a special device.
However, the checks for free space when removing special devices did not
take this into account. This commit corrects that.

In the redaction list traversal code, there is a bug in the binary search
logic when looking for the resume point. Maxbufid can be decremented to -1,
causing us to read the last possible block of the object instead of the one we
wanted. This can cause incorrect resume behavior, or possibly even a hang in
some cases. In addition, when examining non-last blocks, we can treat the
block as being the same size as the last block, causing us to miss entries in
the redaction list when determining where to resume. Finally, we were ignoring
the case where the resume point was found in the buffer being searched, and
resuming from minbufid. All these issues have been corrected, and the code has
been significantly simplified to make future issues less likely.

Investigating influence of scrub (especially sequential) on random read
latency I've noticed that on some HDDs single 4KB read may take up to 4
seconds! Deeper investigation shown that many HDDs heavily prioritize
sequential reads even when those are submitted with queue depth of 1.
This patch addresses the latency from two sides:
- by using _min_active queue depths for non-interactive requests while
the interactive request(s) are active and few requests after;
- by throttling it further if no interactive requests has completed
while configured amount of non-interactive did.
While there, I've also modified vdev_queue_class_to_issue() to give
more chances to schedule at least _min_active requests to the lowest
priorities. It should reduce starvation if several non-interactive
processes are running same time with some interactive and I think should
make possible setting of zfs_vdev_max_active to as low as 1.
I've benchmarked this change with 4KB random reads from ZVOL with 16KB
block size on newly written non-fragmented pool. On fragmented pool I
also saw improvements, but not so dramatic. Below are log2 histograms
of the random read latency in milliseconds for different devices:

Furthermore, the SPA_LOAD_NONE check in vdev_dtl_contains() leads to an
