Make sure the used part of an index block fits into the allocated buffer.
Note : a negative size may cause overflow on 32-bit cpus.

Checked that attributes are [non-]resident when they have to be, and
grouped consistency checks on each of them in a dedicated function.
Consequenly request the checks where needed and remove existing index
checks.
In rare situations, removing an entry from an index root while
rebalancing the index tree, its space was not recovered from the index
root, causing chkdsk to complain. Truncate the index root when this
happens.
Some constraints put on reparse points of unknown type (e.g. they cannot
be deleted) are not acceptable to archivers. This patch removes some
constraints.
Under some rare condition there is no space in an MFT entry to make
an index non-resident, and the index root has to be moved to an extent.
This fix cares for the situation when the attribute list was inserted
beforehand.
When the cluster size is bigger than the index block size, the index
block size unit is 512 (not the sector size) instead of the cluster size.
The partitions formatted by mkntfs and used by ntfs-3g were not
interoperable with Windows when the cluster size is bigger than 4K
and the sector size is not 512.
In rare situations there is not enough space in the base inode entry
to make an index non resident. The index has to be moved to an extent
first. This happens when not using permissions and inserting a file
whose name has 60 chars into a directory whose name has 184 chars.
