	(trivfs_append_args): Report --no-cache if set.
	(check_open_hook): Pass inhibit_cache flag to dev_open.
	* dev.h (struct dev): New member `inhibit_cache'.
	(dev_open): Update decl.
	* dev.c (dev_open): Take new arg inhibit_cache, store in new dev.
	If set, don't initialize buf_offs, io_lock, pager, pager_lock.
	(dev_read, dev_write): If DEV->inhibit_cache is set, allow only
	whole-block i/o: EINVAL for non-whole-block attempts.

	make our own pager; if store_map returns EOPNOTSUPP, so do we.
