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 f36f00a83d artiq_devtool: do not chop up the TCP stream into 1024 byte chunks. 
This makes the smoltcp behavior quite different than without
the TCP forwarding (and can mask smoltcp issues).

whitequark fdb24ef139 coredevice: truncate overlong exception messages.

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.
