Fabian Homborg 3255999794 Bravely set job control to full at startup
We have no idea why this was even a thing. For now simply set it to
"all"/"full" (why these two names? no idea) at startup and allow
changing it later.

Settting it *immediately* when defining the variable sets it too soon
because we don't have the interactive signal handlers
enabled (including the one for SIGTTOU), so let's first settle for
this little piece of awkwardness.

This needs widespread testing, so we merge it early, immediately after
the release.

Fixes #5036
Fixes #5832
Fixes #7721

(and probably numerous others)
