fs/ntfs3: Change right headers to lznt.c
There is lot of headers which we do not need in this file. Delete them
and add what we really need. Here is list which identify why we need
this header.

<linux/kernel.h> // min()
<linux/slab.h> // kzalloc()
<linux/stddef.h> // offsetof()
<linux/string.h> // memcpy(), memset()
<linux/types.h> // u8, size_t, etc.

"debug.h" // PtrOffset()

fs/ntfs3: Change right headers to upcase.c
There is no headers. They will be included through ntfs_fs.c, but that
is not right thing to do. Let's include headers what this file need
straight away.

types.h is needed for __le16, u8 etc.
kernel.h is needed for le16_to_cpu()

fs/ntfs3: Add missing headers and forward declarations to ntfs_fs.h
We do not have headers at all in this file. We should have them so that
not every .c file needs to include all of the stuff which this file need
for building. This way we can remove some headers from other files and
get better picture what is needed. This can save some compilation time.
And this can help if we sometimes want to separate this one big header.

Also use forward declarations for structs and enums when it not included
straight with include and it is used in function declarations input.
This will prevent possible compiler warning:
  xxx declared inside parameter list will not be visible
  outside of this definition or declaration

Here is list which I made when parsing this. There is not necessarily
all example from this header file, but this just proofs we need it.

<linux/blkdev.h> SECTOR_SHIFT
<linux/buffer_head.h> sb_bread(), put_bh
<linux/cleancache.h> put_page()
<linux/fs.h> struct inode (Just struct ntfs_inode need it)
<linux/highmem.h> kunmap(), kmap()
<linux/kernel.h> cpu_to_leXX() ALIGN
<linux/mm.h> kvfree()
<linux/mutex.h> struct mutex, mutex_(un/try)lock()
<linux/page-flags.h> PageError()
<linux/pagemap.h> read_mapping_page()
<linux/rbtree.h> struct rb_root
<linux/rwsem.h> struct rw_semaphore
<linux/slab.h> krfree(), kzalloc()
<linux/string.h> memset()
<linux/time64.h> struct timespec64
<linux/types.h> uXX, __leXX
<linux/uidgid.h> kuid_t, kgid_t
<asm/div64.h> do_div()
<asm/page.h> PAGE_SIZE

"debug.h" ntfs_err() (Just one entry. Maybe we can drop this)

fs/ntfs3: Show uid/gid always in show_options()
Show options should show option according documentation when some value
is not default or when ever coder wants. Uid/gid are problematic because
it is hard to know which are defaults. In file system there is many
different implementation for this problem.

Some file systems show uid/gid when they are different than root, some
when user has set them and some show them always. There is also problem
that what if root uid/gid change. This code just choose to show them
always. This way we do not need to think this any more.

Nls loading is changed a to load with string. This did make code also
little cleaner.

fs/ntfs3: Remove unnecesarry remount flag handling
Remove unnecesarry remount flag handling. This does not do anything for
this driver. We have already set SB_NODIRATIME when we fill super. Also
noatime should be set from mount option. Now for some reson we try to
set it when remounting.

Lazytime part looks like it is copied from f2fs and there is own mount
parameter for it. That is why they use it. We do not set lazytime
anywhere in our code. So basically this just blocks lazytime when
remounting.

fs/ntfs3: Change how module init/info messages are displayed

Change level from notice to info, but keep CONFIG_NTFS3_64BIT_CLUSTER in
notice level. Also this need even more attention so let's put big
warning here so that nobody will not try accidentally use it.

There is also no good reason to display internal stuff like binary tree
search. This is always on option which can only disabled for debugging
purposes by developer. Also this message does not even check if
developer has disabled it or not so it is useless info.

3) If indx_new() fails then it will lead to an error pointer dereference

fs/ntfs3: Use kernel ALIGN macros over driver specific
The static checkers (Smatch) were complaining because QuadAlign() was
buggy.  If you try to align something higher than UINT_MAX it got
truncated to a u32.

Smatch warning was:
	fs/ntfs3/attrib.c:383 attr_set_size_res()
	warn: was expecting a 64 bit value instead of '~7'

So that this will not happen again we will change all these macros to
kernel made ones. This can also help some other static analyzing tools
to give us better warnings.

Patch was generated with Coccinelle script and after that some style
issue was hand fixed.

fs/ntfs3: Fix integer overflow in multiplication
The multiplication of the u32 data_size with a int is being performed
using 32 bit arithmetic however the results is being assigned to the
variable nbits that is a size_t (64 bit) value. Fix a potential
integer overflow by casting the u32 value to a size_t before the
multiply to use a size_t sized bit multiply operation.
