Subject: Merged NetBSD version, as they have done improvements: 	1.
 ntfs_read*attr*() functions now accept 	uio structure to eliminate one
 data copying. 	2. found and removed deadlock caused 	by 6 concurent ls -lR.
 	3. started implementation of nromal 	Unicode<->unix recodeing.

Obtained from:	NetBSD
