Fixed computing the replacement bytes in ntfswipe
The computing of replacement bytes for overwriting undeletable files
uses random values and standard ones instead of the values provided in
option --bytes. Fix the mixup between both logics, mention the difference
in the documentation and reject defining both options --bytes and --undel.

Removed the loader from boot image
The license for using the boot loader which used to be inserted by mkntfs
is unclear, so remove it, and only keep the boot sector restricted to
what is needed for having it recognized as such. The space for a loader
is still reserved so that an operating system being installed can insert
its own loader.

Fixed expanding $STANDARD_INFORMATION with almost-full MFT record
When setting a security descriptor on an NTFS v1.2 format file in an
NTFS v3.0+ volume, NTFS-3G would migrate $STANDARD_INFORMATION to the
new format, which requires extending its size from 48 to 72 bytes. If
this happened while the file's MFT record was almost full, and none of
the file's attributes could be made non-resident, and the file did not
have an attribute list attribute, then the operation would unexpectedly
fail with ENOENT. Fix this by adding an attribute list to the file in
this situation.

Allowed names with trailing dot or space on conditions
Windows places filenames with a trailing dot or space in the Win32
namespace and allows setting DOS names on such files. This is true even
though on Windows such filenames can only be created and accessed using
WinNT-style paths and will confuse most Windows software. Regardless,
because libntfs-3g did not allow setting DOS names on such files, in
some cases it was impossible to correctly restore, using libntfs-3g, a
directory structure that was created under Windows.
Update ntfs_set_ntfs_dos_name() to permit operating on a file that has a
long name with a trailing dot or space. But continue to forbid creating
such names on a filesystem FUSE-mounted with the windows_name option.
Additionally, continue to forbid a trailing a dot or space in DOS names;
this matches the Windows behavior.
