- move ntfs consistency check to libntfs (for ntfsck, ntfsclone, etc)

There are a few very rarely met restrictions at present: filesystems having
unknown bad sectors, relocation
of the first MFT extent and resizing in the middle of some metadata
in some cases aren't supported yet. These cases are detected and
resizing is refused, restricted to a safe size or the closest safe
of the first MFT extent and resizing into the middle of a $MFTMirr extent
aren't supported yet. These cases are detected and
resizing is restricted to a safe size or the closest safe
size is displayed.
