compiler: in codegen for delay(), round fp instead of truncating.
...
Consider delay(8*us). It results in the following computation...
>>> 8*1e-06/1e-09
7999.999999999999
with the result promptly getting truncated to 7999.
Fixes #706 .

conda: limit git hashes in build numbers to 8 chars exactly.
...
Before this commit, a nasty edge case was possible where repositories
on different builders have had different sets of objects fetched
into them, and so git-describe selected different lengths for
abbreviating hashes.

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 .
