fw3 fails to connect to ubus

Username: Paul Traina

I’m marking this critical because it completely breaks firewalls and NAT and is likely to cause quite a bit of grief.

Additionally, I’m submitting it as an incomplete work-in-progress because it is such a critical bug and I want to give an early heads-up.

Device is a ath79 - Archer C7v2.

Bug does not occur in OpenWrt SNAPSHOT r7360-e15565a0 (master as of July 8th or so)

Bug does occur in OpenWrt SNAPSHOT, r7558-a5c3bbaf (master as of July 25th)

There have been several updates to ubus and one to the firewall code.

It is also, possibly, a tools/compiler migration bug, as the master branch was NOT rebuilt from scratch and instead was just pulled and rebuilt.

I am re-creating my compile environment from scratch and rebuilding the tree from scratch and will report back.
