0d0ddf2e58 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.

c6e8d5c901 runtime: allow setting UART log level explicitly.
This is way more convenient than commenting out parts
of session.rs when debugging.

0531dc45c3 DMA: erase trace before re-recording it.
Or we could needlessly OOM replacing a large trace.

9dfe9c1248 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.

3a1fc729cf compiler: refactor type annotations recognizing in kernels.
The new implementation is much more generic, more robust,
and shares code with the same for syscalls as well as RPCs.
