Completed moving Upstream to interrupt-based SPI.
...
Although I am not entirely convinced this is necessary, as the SPI data
stall issue only appeared with optimisation off (-O0). Perhaps re-visit
this if Upstream needs more free CPU time later...

Added priority elevation to Downstream USB host processing code that
...
interacts with SPI.
It elevates to USB_OTG priority to avoid preemption by SPI, DMA, or USB
interrupts thus avoiding synchronisation issues between USB host stack
and SPI interface.
Also minor improvements to Downstream error handling.

Refactor a bunch of stuff in Upstream project to avoid endless confusion
...
with Downstream project.
Also fixed a couple of things in upstream_spi.c and
upstream_interface_msc.c but due to file rename the diff is not
obvious...
