I'm soliticing feedback on those patches that I've sent recently - I've
elided patches if they have some unresolved issue.

I'm not aware of any loose ends other than what's updated here:

- cirrus: code coverage

I changed this to also run an "initial" coverage report before running
tests.  It's not clear to me what effect that has, though...

Andres seems to think it's a problem that this shows coverage only for
files that were actually changed.  But that's what's intended; it's
sufficient to see if new code is being hit by tests.  It would be slow
and take a lot of extra space to upload a coverage report for every
patch, every day.  It might be nice for cfbot to show how test coverage
changed in the affected files: -15% / +25%.

- cirrus: upload changed html docs as artifacts

Fixed an "only_if" line so cfbot will run the "warnings" task.

Maybe this path is waiting on Andres' patch to "move CompilerWarnings to
meson" ?

It's adjustable by un/setting the environment variable.

I'm surprised to hear that anyone using cirrusci (with or without cfbot)
wouldn't prefer the behavior this patch implements.  It's annoying to
search find the logs for the (typically exactly one) failing test in
cirrus' directory of 200some test artifacts.  We're also uploading a lot
of logs for every failure.  (But I suppose this might break cfbot's new
client side parsing of things like build logs...)
