* 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.
