Robert Jördens 2f1029c292 Revert "sawg: advance dds 1/2 by one sample group" 
This reverts commit 8e0a1cbdc8.

c.f. #772

The underlying issue is still the same. You will always find something that does not match when trying to compare the DDS with the parallelized DUC. They are just different. I could correct it for phase but then it will fail for amplitude. Or you'll compare the offset channel to phase1 or amplitude1. Let's state that equal things are well synchronized but unequal things may have a deterministic latency difference of strictly less than one coarse RTIO cycle.

Robert Jördens 55b5b87490 fir: simplify latency compensation 
Don't try to tweak out the last bit of latency by feeding the HBF input
early. Instead feed it late so the interpolated samples are early and
the latency is an even multiple of the super-sample cycle.

whitequark f17a6616b2 runtime: ensure management interface buffer can hold log buffer. 
Otherwise we get weird edge cases where the network stack could try
to append to log buffer while management interface is holding
the log buffer and trying to push it out, and it's just no good.

The serialized log buffer at its maximum length is slightly longer
than 32 KiB, so we just allocate the largest possible TCP buffer
to the management interface to keep it simple.

Robert Jördens 9a8a7b9102 sawg: handle clipping interpolator 
* give 1 bit headroom to interpolator to handle overshoot
* fix Config limiter widths (NFC)
* move clipper to behind the HBF to correctly shield DUC

This leaves a factor of two headroom for the sum of the following
effects:

  * HBF overshoot (~15 % of the step)
  * A1/A2 DDS sum

While this is technically not sufficient and can still lead to
overflows, it is unlikely that one would trigger those. It would require
doing large amplitude A1, large amplitude A2 and additionally doing
amplitude/phase jumps that would overshoot the HBF. No sane person would
try that, right?
