Fix inflated quiesce time caused by lwb_tx during zil_commit()
In current zil_commit() process, transaction lwb_tx is assigned in
zil_lwb_write_issue(), and is committed in zil_lwb_flush_vdevs_done().
Thus, during lwb write out process, the txg is held in open or quiesing
state, until zil_lwb_flush_vdevs_done() is called. If the zil's zio
latency is high, it will cause txg_sync_thread() to starve.
The goal here is to defer waiting for zil_lwb_flush_vdevs_done to the

In this patch, it achieves the goal without holding transaction.
A new function zil_lwb_flush_wait_all() is introduced. It waits for

More speculative prefetcher improvements
- 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.

zed: Take no action on scrub/resilver checksum errors
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.
