- Assisted in design and debug by Joel Sherrill <joel@…>.
- mongoosev/duart/mg5uart.c, mongoosev/duart/mg5uart.h,
mongoosev/include/mongoose-v.h, mongoosev/vectorisrs/vectorisrs.c,
shared/interrupts/maxvectors.c: Now works. Significant rework
of exceptions and interrupt vectoring to clean things up.
- shared/interrupts/vectorexceptions.c: Removed.
- shared/interrupts/Makefile.am: Reflects above.
