* Assisted in design and debug by Joel Sherrill <joel@OARcorp.com>. * 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.
