Better diagnostics for full FFO allocations

[ZLLentz]

When a PLC doesn't have enough PMPS fast fault allocations, the PLC output will fault without any other indication in the pmps-ui.

Goal: improve the diagnostic to let us know when this situation is happening.

We currently show the counts of allocated/in use/faulted FFOs on the ioc/plc status page. Since the counts here are summed from FFO1, FFO2, FFO3, ... they can't be considered a useful diagnostic tool for when the PLC has more in-use fast faults than allocated fast faults.

Ideas:

• Separate the allocated/in use counters per FFO
• Create a warning indicator somewhere visible on the main screen when this happens
• Create a fast-fault-looking thing and add it to the fast fault table to represent this event

This happened again today, this time in RIX. If we could have caught this ahead of time it would have helped a lot.

I think what we should actually do is extend this mostly empty arbiter outputs table:

There is plenty of room to the right to get extra info for each FFO:

• Number of FFs allocated in the screen
• Number of FFs allocated in the PLC
• Number of FFs connected
• Number of FFs tripping
• Warning light for full allocation
