I make out some draft pseudo-code of fifo bufferring (see attachment if you
like. I do not expect to bother mentors to read it since it is just rough
scratch). It is not completed and has not been inspected, so may have
defects, and I still need time to learn the code style of RTEMS.

And, we still need to hook some of IMFS handlers to transit to FIFO routines
for FIFO nodes.
