he | Make the scaling of the "bytes written" sticky, so that if we go
to K, we don't return to unscaled, and similar for higher scales
(though it takes some effort, due to the wide field...)
Fixes PR#54334.

Use I/O timestamps to compute disk statistics for better precision.
Disk statistics are collected in a fixed size array, that got corrupted
when a disk was detached. Adapt by skipping entries of detached disks
and detect reused disknames at the array end.

mlelstv | branches: 1.4.4;
Enhance disk metrics by calculating a weighted sum that is incremented
by the number of concurrent I/O requests. Also introduce a new disk_wait()
function to measure requests waiting in a bufq.
iostat -y now reports data about waiting and active requests.
So far only drivers using dksubr and dk, ccd, wd and xbd collect data about
waiting requests.

Update statistics reporting to use new kernel framework, rename dkstats*
to a more generic name since it no longer just deals with disk.
