Merge branch 'merge_next' (which merges next)
This has been in the making far too long.
We finally merge the next branch into master, in preparation of
releasing GNU Radio 3.8.
There will be breakage.
There will be awesomeness.
There will be progress in the greatest SDR framework to ever grace the
surface of the earth.
Hold tight for now.
