* Lots of tinkering and tuning as part of improving interrupt latency
and improving the per-task interrupt level control and FP mask handling.
With these modifications interrupt latency was measured at a worst-case
of 100us, average below 60 us on a 12 Mhz R3000 class CPU with 50
RTEMS tasks in the application.
* mongoosev/README: Updated.
* mongoosev/include/mongoose-v.h: Masks modified.
* mongoosev/vectorisrs/vectorisrs.c: Significant overhaul to address
software prioritization of interrupts. If a higher priority interrupt
occurs while we are looking for new interrupts, we will reinitiate the
scan of all interrupts.
* shared/interrupts/vectorexceptions.c: Removed warning and deleted
blank lines.
