Applied.

Thanks Krzysztof.

FYI, I built neard natively with these patches applied on an amd64
(ubuntu 20.04) and an ARM Cortext A8 (debian 10).  Both build cleanly
and I could read & write tags.

My plans include:
- python3-ize the python test scripts
- debug an issue I think I saw
- look for races that I recall running into in the past
- recruit another arm SoC for testing
- get my trf7970 working again

When things settle down and we're happy with what we have, we should
cut a new version (0.17 or 1.0 even).
