fs: buffer Fugue writes through RAM
...
Writing from ROM causes occasional crashes, which are fairly hard to
produce when the buffers are small.

fs: use a static variable in calls to BFile_Create()

There is no evidence that BFile_Create() keeps the address and writes
to it later on, but I'd rather be overly careful than have to debug a
stack corruption problem in half a year :)

dma: do not use ICS in foreign unbinds
...
I'm pretty sure it makes no difference because the OS does not rely on
interrupts for most (if not all) of its DMA operations, but it's better
to keep it clean anyway.

dma: remove IE flag at end of transfer

This should have no effect since the channel is disabled, but it's much

fs: track offset of Fugue files manually
...
This helped locate some bugs:
* read() could read past EOF due to BFile_Read() allowing you to read up
until the end of the last sector, beyond the file size
* pread() did not restore the file offset because the negative seek at
the end is not relative (that was the CASIOWIN fs API), so pread()
could not actually be written without knowing the current position
* lseek() would clamp you to EOF but still return its out-of-bounds
arguments, as a direct result of BFile_Seek() doing that
Benefits:
* Made pread() a generic function

I saw a crash with the 12 kB stack. Added an error message to diagnose
further similar issues, and bumbed the stack to 14 kB. That's a lot of
space just for BFile but stability is queen... :x
