arla-0.38 on FreeBSD/amd64

[Garrett Wollman]

I ran into a few issues getting Arla to compile and (seemingly) work
on FreeBSD/amd64.  The most significant one has to do with the build
system for kernel modules on amd64.  I would suggest that, in general,
one cannot expect to use any build system for kernel modules other
than that supported by the operating system; my attempts to hack
correct module building into the existing makefile resulted in failure
(and in one case a kernel panic).  Since the infrastructure is there,
and it results in a dramatically simpler Makefile, it would probably
be better to use it.  (It's essential in my case since I need to
supply the KERNCOMPILEDIR variable to use the correct global compile
options for my custom kernel.)

There still remain a number of LP64 and other type bugs in the 0.38
release.  The enclosed patches fix the ones I noticed.  There may
still be others, as I noticed that writes did not work for anonymous
users with "system:anyuser rli" or "system:anyuser rlidwk".
(Interestingly, the *create* operation worked; it was just the write
that failed.)

The first patch may be essential, since register_t is 64 bits on LP64.
The other patches mostly fix debugging output; size_t != int on LP64.
