infra: rewrite brick_say to work with threads
...
It was cumbersome to write to files in / after in_interrupt() & co.
A master write thread will also reduce the peak IO parallelism
on log data in /mars .
Further work has to be done to utilize non-default write channels.

all: IO scheduling improvements, tuning
...
Dastically boost random write performance on RAID controllers with BBUs.
Writeback is only performed when there is no IO contention / starvation.
The old IO contention controller was suited to workstations.
Now server loads are well-controlled even when BBUs are present.
