IOTA
- implement iota panic ("dead") codes
- fix uih interrupt window condition leading to iota machine stack
overflow and/or phantom interrupt detection
- fix iota static machine stack init value
- refactor UIH for both IOTA and PK to pull the priority table from a
common source
- the entire INTERCME0 IRQ handler in PK is executed with EE=0, for IOTA
this can only be emulated by masking all higher priorities in the UIH
for that particular task/interrupt priority group
