Fixed the detection of the end of attribute list
...
The recent detection of a truncated attribute list entry overlooked the
normal detection of the end of list. Moreover the check for name
overflow is to be done later and not needed at this stage.

to be caught by an arithmetic overflow.

Reset the resident attribute offset when appending from none

When there is no resident attribute value, its offset is unsafe, so better
to recompute it when appending data.

Avoided endless recursions when allocating the main bitmap
...
Allocating clusters to the main bitmap may imply updating the bitmap
itself within a cluster not yet allocated. This can turn into endless
recursions and has to be rejected. Currently the bitmap is assumed
to be fully allocated.

Skipped errors for bad free clusters before they are computed
...
The count of free clusters may be updated while mounting before it
has been initialized, which may lead to irrelevant error messages.
Moreover the count is not computed at all in some ntfsprogs utilities.
So set up a flags to avoid outputting irrelevant errors.

Fixed the computation of the end of index entry
...
The end of an index entry is related to its full length, not to the
length of the key. Added an error message in an overflow case.

Checked that indexes do not exceed the index block size
...
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.

Restricted the attribute definition table size to 24 bits
...
The standard size is 2560 bytes. It can be extended for specific purposes,
but its former limit to 32 bits was unreasonable. Anyway ntfs-3g is
not committed to support non-standard situations.

grouped consistency checks on each of them in a dedicated function.
Consequenly request the checks where needed and remove existing index
checks.

Aborted mounting when cannot access standard information of MFT
...
The standard information of the MFT must be its first attribute in the
base record. If it is not accessible initially, we end up searching it
in an extent before the MFT struct is ready for that.

the correct direction.

Checked attributes layout against length actually used
...
The end of the attributes must be checked against the space in use
rather than the allocated space. This contributes to the safety of
subsequent attribute resizing.

Checked the MFTMirr lcn to be consistent with the boot sector

The lcn of the initial run of the MFTMirr data must be the same as
described in the boot sector. As a consequence this cannot be a hole.

Made sure an error code is issued for failed mounts
...
In case of failure to mount a file system, an error code is expected to
indicate the failure reason. In an unclear case the error code was not
set, so force an EIO when this happens.

Added a consistency check of attribute size in readall()
...
Make sure the attribute designated to readall() has a reasonable size.
Apart from a bitmap, in a valid call, the attribute size is limited to
65536, and bitmaps are limited by the number of cluster.

Cleaned the tail of compressed buffer before writing a full cluster
...
When appending to an existing compressed file, the last block must first
be decompressed. When doing so, clear the tail of buffer in order to not
leak unrelated data.

Rejected updates of uninitialized MFTMirr
...
Reject updating uninitialized MFTMirr because it leads to endless
recursions as updating the MFTMirr entry of MFT implies further updating
MFTMirr.
This is probably specific to ntfsfix, as mounts are normally rejected
when MFTMirr does not match MFT.
