devel: rename 'all' to 'all-warnings' (BC)
We have started to isolate extra usecases for developer-only output
that is not a warning. As the section has the fairly generic name
'devel' it makes sense to tuck them there. As a result, 'all' becomes
a bit misleading so we rename it to 'all-warnings'. This will break
some developer setups but the tests are still fine and developers will
likely spot this change.
