trans_logger: fix potential race on log_input
...
During logrotate, there may exist writeback clusters
with mixed log_inputs. Each sub_mref now gets its individual
log_input inherited from the orig_mref. Add ref counting
to ensure that cleanup can never occur on an active log_input.

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.
