84e42e1daf For cygwin hosts, we need to use the return value from the read 
routine as the number of bytes to process.  This apparently is due to
text-mode vs binary-mode.  If the mounts are done text-mode, then the
size returnedby fstat() may be different than the number of bytes
"read" in text mode.

121d6745bc * Monster bug fixes & improvements from the last two days' demo-testing work. 
* sky-pke.h (pke_fifo*): Exported these formerly private functions.
	(pke_device): Added FIFO cache fields.

	* sky-pke.c (pke_fifo_reset): New function for GPUIF client -
 	clear FIFO contents.

 	calculations to handle out-of-range VU memory addresses.
	(*): Replaced many previous uses of MEM[] and state->uMEM[] with
	calls to above macros.

	* sky-vu.h (struct VectorUnitState): Added qw/dw size fields for
	MEM/uMEM buffers, for overflow prevention.  Renamed MEM/uMEM fields
	to catch all their prior users.

	* sky-vu0.c (vu0_attach): Manually align MEM0/MEM1 buffers to force
	16-byte alignment.  (zalloc is not enough.)

	used as a modulus for periodic refresh.
	(refresh): New function to send GPU2 refresh code periodically.
