	venusop.c -- routines that are specific to Vice file system, doing Venus operations

	VenusFlush(pathname): take a pathname and do an ``fs flush'' op.

	VenusFetch(pathname): take a pathname and pre-fetch it.

	VenusCancelStore(fid): prevent the close(fid) from storing the file.

	VenusFlushCallback(pathname): flush the callback, but not the data, for the named file.

	All routines return the result of the pioctl/ioctl and leave error codes in errno.
