clean up some gross static mut state stuff
...
still have to resolve the static mut issue of getting the USB
controller state into the interrupt controller.
I'm not sure there *is* a good way to do it - this might actually
be "the" use case for static mut's - but the point of this
exercise was to just diff out the driver in machine mode versus
OS mode to try and figure out if there's a hardware problem
causing instability or if it's a driver issue
the conclusion so far is that the USB stack requires extremely
tight interrupt handling timing, and so, for better stability
we may have to mirgate away from the heavily user-space dependent
implementation currently in use.

add usb mass storage command handlers
...
disk enumerates now, and initiates r/w transactions but
the reference driver does not match the implementation in that
the USB stack can't access all of RAM, so we have to add
an intermediate stage that splits the command requests into
smaller chunks
