Attached is a rebased version of this patch series, with the above patch as
0001.
The later patches have a lot, but not yet all, of Melanie's feedback
addressed. I mainly am sending them because cfbot wanted a rebase anyway.
I'm mainly not yet happy with how 0007 changes buf_internals.h, some more
comment work is also needed. 0009 & 0010 still are more for POC than ready to
be in-depth reviewed.
Greetings,
Andres Freund
