DMA: erase trace before re-recording it.
...
Or we could needlessly OOM replacing a large trace.

DMA: improve recording performance.
...
This commit moves DMA serialization code to the kernel CPU
(to cope with the existence of rtio_output_wide) and batches
the resulting sequences. This results in less data being transferred
between kernel and comms CPUs (24 octets with one pointer before,
18 octets with no pointers now, for the common case of rtio_output),
but most importantly reduces cache flushes, which now happen
once per 64k octets.
On average, it now takes about 15us to record a single RTIO event
in a DMA trace.
Fixes #712 .
