Remove tabs before spaces from comment as recommended by kernel coding
style. Checkpatch also warn about these.

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()

Capitalize comments and end with period for better reading.
Also function comments are now little more kernel-doc style. This way we
can easily convert them to kernel-doc style if we want. Note that these
are not yet complete with this style. Example function comments start
with /* and in kernel-doc style they start /**.
Use imperative mood in function descriptions.
Change words like ntfs -> NTFS, linux -> Linux.
Use "we" not "I" when commenting code.

Problem with these wrapper is that we cannot take off example GFP_NOFS
flag. It is not recomended use those in all places. Also if we change
one driver specific wrapper to kernel wrapper then it would look really
weird. People should be most familiar with kernel wrappers so let's just
use those ones.
Driver specific alloc wrapper also confuse some static analyzing tools,
good example is example kernels checkpatch tool. After we converter
these to kernel specific then warnings is showed.
Following Coccinelle script was used to automate changing.

This patch adds different types of NTFS-applicable compressions:
- lznt
- lzx
- xpress
Latter two (lzx, xpress) implement Windows Compact OS feature and
were taken from ntfs-3g system comression plugin authored by Eric Biggers
(https://github.com/ebiggers/ntfs-3g-system-compression)
which were ported to ntfs3 and adapted to Linux Kernel environment.
