ntfs: add Kconfig and Makefile

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).

+         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

+       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.

+         POSIX Access Control Lists (ACLs) support additional access rights
+         for users and groups beyond the standard owner/group/world scheme.
+
+         This option enables ACL support for ntfs, providing functional parity
+         with ntfs3 drivier.
+
+         NOTE: this is linux only feature. Windows will ignore these ACLs.
+
+         If you don't know what Access Control Lists are, say N.
