A bunch of fixes to limit invalid joiner combinations earlier, during
mode enumeration and compute config. Patch 1 is v2 of [1], the rest are
new.

I decided to drop Fixes: and Cc: stable for now, just to thread
carefully. There are no bug reports about this that I know of, and we
can trivially ask for backports as needed.

BR,
Jani.
