Bit shifts should be done on unsigned type as a matter of good practice
to avoid any problems with bit overflowing to the sign bit.

Previously the XFS-specific code was commented out so we don't need the
headers for building fsstress, this changes how the utility behaves
compared to the one in fstests, e.g. randomness or additional open/close
operations. Add enough code from xfsprogs to make it compile and enable
the #if0-ed code.

'HAVE_BTRFSUTILS_H' is defined.

The *64 interfaces, such as fstat64, off64_t, etc, are legacy interfaces
created at a time when 64-bit file support was still new. They are
generally exposed when defining a macro named _LARGEFILE64_SOURCE, as
e.g. the glibc docs[0] say.
The modern way to utilise largefile support, is to continue to use the
regular interfaces (off_t, fstat, ..), and define _FILE_OFFSET_BITS=64.
We already use the autoconf macro AC_SYS_LARGEFILE[1] which arranges this
and sets this macro for us. Therefore, we can utilise the non-64 names
without fear of breaking on 32-bit systems.
This fixes the build against musl libc, ever since musl dropped the
*64 compat from interfaces by default[2] just for _GNU_SOURCE, unless
_LARGEFILE64_SOURCE is defined. However, there are plans for a future
removal of the whole *64 header API, and that workaround (adding another
define) might cease to exist.
So, rename all *64 API use to the regular non-suffixed names. For
consistency, rename the internal functions that were *64 named
(lstat64_path, ..) too.
This should have no regressions on any platform.

The fsstress tool is a useful file generator, pull it from fstests as
it's not packaged as a standalone tool anywhere and the LTP version is
out of date.
The file has been modified to build, some xfs-specific ioctls are not
supported.
