Use the same trick as we do for ASSERT() to make DNODE_VERIFY() use
its parameter at compile time without actually using it at run time

- Make prefetch distance adaptive: up to 4MB prefetch doubles for
every, hit same as before, but after that it grows by 1/8 every time
the prefetch read does not complete in time to satisfy the demand.
My tests show that 4MB is sufficient for wide NVMe pool to saturate
single reader thread at 2.5GB/s, while new 64MB maximum allows the
same thread to reach 1.5GB/s on wide HDD pool. Further distance
increase may increase speed even more, but less dramatic and with
higher latency.
- Allow early reuse of inactive prefetch streams: streams that never
saw hits can be reused immediately if there is a demand, while others
can be reused after 1s of inactivity, starting with the oldest. After
2s of inactivity streams are deleted to free resources same as before.
This allows by several times increase strided read performance on HDD
pool in presence of simultaneous random reads, previously filling the
zfetch_max_streams limit for seconds and so blocking most of prefetch.
- Always issue intermediate indirect block reads with SYNC priority.
Each of those reads if delayed for longer may delay up to 1024 other
block prefetches, that may be not good for wide pools.

This issue was discovered by zloop runs. When a mirror or other
redundant top-level vdev has a disk failure, and the disk is replaced,
the rebuild process occurs. A removal can happen while this is in
progress. If the removal completes before the rebuild does, the
removal process will try to free the vdev that is still in use.

When scrubbing/resilvering a pool it can be counter productive to
cancel the scan and kick of a replace operation to a hot spare
when encountering checksum errors. In this case, the best course
of action is to allow the scrub/resilver to complete as quickly
as possible and to keep the vdevs fully online if possible.
Realistically, this is less of an issue for a RAIDZ since a
traditional resilver must be used and checksums will be verified.
However, this is not the case for a mirror or dRAID pool which is
sequentially resilvered and checksum verification is deferred
until after the replace operation completes.
Regardless, we apply this policy to all pool types since it's
a good idea for all vdevs. Degrading additional vdevs has the
potential to make a bad situation worse. Note the checksum
errors will still be reported as both an event and by
`zpool status`. This change only prevents the ZED from
proactively taking any action.

We want `zpool import` to be highly robust and never panic, even
when encountering corrupt metadata. This is already handled in the
arc_read() code path, which covers most cases, but spa_load_verify_cb()
relies on zio_read() and is responsible for verifying the block pointer.
During import it is also possible to encounter blocks pointers which
contain ZIO_COMPRESS_INHERIT and ZIO_CHECKSUM_INHERIT values. Relax
the verification function slightly to allow this.
Futhermore, extend dsl_scan_recurse() to verify the block pointer
contents of level zero blocks which are not of type DMU_OT_DNODE or
DMU_OT_OBJSET. This is handled by arc_read() in the other cases.
