Following a recent patch to the fuse kernel, the Posix ACL checks can
be done within the kernel instead of having to be done in the file
system, provided lowntfs-3g is used.
This mode is still not used by default until the fuse patch is
released by distributions.
Switch to the standard autoconf AC_HEADER_MAJOR macro which takes care
of the ugly details like when to use mkdev.h and when to use sysmacros.h.
(requires <sys/types.h> to be included)
Also include these in all files that use major/minor/makedev funcs.

On Solaris/OpenIndiana, the major and minor fields in st_rdev have to
be represented on 14 bits and 18 bits respectively. They must have
the same representation on 32-bit and 64-bit builds as the kernel
and the library do not know the word size of each other.
On OpenIndiana 64-bits, st_rdev has major and minor as 32-bits wide each,
but the fuse protocol (common to 32-bit and 64-bit) has an st_rdev field
limited to 32-bit. For now, pack major and minor the same way as in the
32-bit variant (14 and 18 bits).
The support for ioctls has been added to fuse when using protocol 7.18,
and an equivalent upgrade has been done in fuse lite with commit [ae9aee].
For old kernels, a fall back to protocol 7.8 was implemented, but this
appears not to be supported in not-so-old kernels (e.g. 2.6.35).
With this patch, the fall back protocol is set to 7.12 or to the highest
level supported by the kernel.
This is backporting code from the full FUSE library in order to support
ioctls. The fuse protocol level negociated is now 7.18 instead of 7.8.
A fallback protocol to 7.8 is provided for compatibility with older kernels.
32-bit ioctls are not supported by a 64-bit library
The libfuse used by OpenIndiana has the same features as libfuse-lite
though requiring some code variants. Merging them simplifies supporting
both.
Variants for OpenIndiana are selected when defining __SOLARIS__
