In automated ZTS runs, I'd occasionally hit

because there weren't any write errors.
The reason is that we're not syncing the zpool before `zinject -c`.
If the writes by `dd` aren't synced out at the time `zinject -c` runs,
they will not hit an error and we'll hit the log_fail above.

There are a couple changes included here. The first is to introduce
a cap on the size the ZED will grow the zevent list to. One million
entries is more than enough for most use cases, and if you are
overflowing that value, the problem needs to be addressed another
way. The value is also tunable, for those who want the limit to be
higher or lower.
The other change is to add a kernel module parameter that allows
snapshot creation/deletion to be exempted from the history logging;
for most workloads, having these things logged is valuable, but for
some workloads it produces large quantities of log spam and isn't
especially helpful.

buffers with potentially incorrect parity data are then just freed,
while new recalculated ones are used for repair.

Issuing several scrub reads for a block we may use the parent ZIO
buffer for one of child ZIOs. If that read complete successfully,
then we won't need to copy the data explicitly. If block has only
one copy (typical for root vdev, which is also a mirror inside),
then we never need to copy -- succeed or fail as-is. Previous
code also copied data from buffer of every successfully completed
child ZIO, but that just does not make any sense.
On healthy N-wide mirror this saves all N+1 (or even more in case
of ditto blocks) memory copies for each scrubbed block, allowing
CPU to focus mostly on check-summing. For other vdev types it
should save one memory copy per block copy at root vdev.
