NTFS 2.1.17 release

Hi Andrew, Hi Linus, please do a

	bk pull bk://linux-ntfs.bkbits.net/ntfs-2.6

This is quite a big update and all of it has been in -mm kernels for a 
while.  I have been holding off until 2.6.8 had been released before 
submitting so any problems would have time to get to me.  I haven't had 
any problem reports so here it is.  The most important points are that 
NTFS now provides most of the facilities provided by other Linux fs, e.g.:
	- fsync/fdatasync/msync
	- access {a/m/c}time updates
	- readv/writev
	- aio_read/aio_write
Also several bugs in the mount code error paths were fixed and a global 
variable got eliminated as a result.  See below for details ChangeSet 
comemnts.

Please apply.  Thanks!

For the benefit of non-BK users and to make code review easier, I am
sending each ChangeSet in a separate email as a diff -u style patch.

Best regards,

	Anton
