The hidedotfiles mount option provides the same functionality as
the NTFS-3G hide_dot_files mount option. As such, it should be
named the same for compatibility with NTGS-3G.
Rename the hidedotfiles to hide_dot_files for compatbility with
NTFS-3G.

Currently, the ntfs3 driver does return the hidedotfiles mount
option in the list of enabled mount options. This can confuse
users who may doubt they enabled the option when not seeing in
the list provided by the mount command.
Add hidedotfiles mount option to the list of enabled options
provided by the mount command when it is enabled.

Currently, the hidedotfiles mount option is behaving in the reverse
way of what would be expected: enabling it disables setting the
hidden attribute on files or directories with names starting with a
dot and disabling it enables the setting.
Reverse the behaviour of the hidedotfiles mount option so it matches
what is expected.

In ntfs_init_fs_context we allocate memory in fc->s_fs_info.
In case of failed mount we must free it in ntfs_fill_super.
We can't do it in ntfs_fs_free, because ntfs_fs_free called
with fc->s_fs_info == NULL.
fc->s_fs_info became NULL in sget_fc.

Some discussion has been spoken that this deprecated mount options
should be removed before 5.15 lands. This driver is not never seen day
light so it was decided that nls mount option has to be removed. We have
always possibility to add this if needed.
One possible need is example if current ntfs driver will be taken out of
kernel and ntfs3 needs to support mount options what it has.

Right now sb blocksize first get initiliazed in fill_super but in can be
changed in helper function. It makes more sense to that this happened
only in one place.
Because we move this to helper function it makes more sense that
s_maxbytes will also be there. I rather have every sb releted thing in
fill_super, but because there is already sb releted stuff in this
helper. This will have to do for now.

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.
