This introduce Kconfig and Makefile for remade ntfs.
And this patch make ntfs and ntfs3 mutually exclusive so only one can be
built-in(y), while both can still be built as modules(m).

+config NTFS_FS

+ help
+ NTFS is the file system of Microsoft Windows NT, 2000, XP and 2003.
+ This allows you to mount devices formatted with the ntfs file system.
+
+ To compile this as a module, choose M here: the module will be called
+ ntfs.
+
+config NTFS_DEBUG
+ bool "NTFS debugging support"
+ depends on NTFS_FS
+ help
+ If you are experiencing any problems with the NTFS file system, say
+ Y here. This will result in additional consistency checks to be
+ performed by the driver as well as additional debugging messages to
+ be written to the system log. Note that debugging messages are
+ disabled by default. To enable them, supply the option debug_msgs=1
+ at the kernel command line when booting the kernel or as an option
+ to insmod when loading the ntfs module. Once the driver is active,
+ you can enable debugging messages by doing (as root):
+ echo 1 > /proc/sys/fs/ntfs-debug
+ Replacing the "1" with "0" would disable debug messages.
+
+ If you leave debugging messages disabled, this results in little
+ overhead, but enabling debug messages results in very significant
+ slowdown of the system.
+
+ When reporting bugs, please try to have available a full dump of
+ debugging messages while the misbehaviour was occurring.
+
+config NTFS_FS_POSIX_ACL
+ bool "NTFS POSIX Access Control Lists"
+ depends on NTFS_FS
+ select FS_POSIX_ACL
+ help
+ POSIX Access Control Lists (ACLs) support additional access rights
+ for users and groups beyond the standard owner/group/world scheme,
+ and this option selects support for ACLs specifically for ntfs
+ filesystems.
+ NOTE: this is linux only feature. Windows will ignore these ACLs.
+
+ If you don't know what Access Control Lists are, say N.

Maybe add the explicit dependency also there for clarity? Thanks, Amir.
