call by nfsd to set up the file descriptors that are
sent to the kernel. The flag causes the getaddrinfo()
to fail, with EAI_NONAME, when there is not a non-loopback
network interface configured.

(mountd and statd in particular). That could be a problem in the future
if someone were to boot a kernel that supports IPv6 serving with an
older nfs-utils. For now, hardcode the IPv6 switch into the off position
until the other daemons are functional.

IPv6 sockets for knfsd can't be allowed to accept IPv4 packets. Set the
correct option to prevent that from occurring on IPv6 sockets.

Convert nfssvc_setfds to use getaddrinfo. Change the args that it takes
and fix up nfssvc function to pass in the proper args. The things that
nfssvc has to do to call the new nfssvc_setfds is a little cumbersome
for now, but that will eventually be cleaned up in a later patch.
nfs-utils: break up the nfssvc interface
Currently, the only public interface to the routines in nfssvc.c is
nfssvc(). This means that we do an awful lot of work after closing
stderr that could be done while it's still available.
Add prototypes to the header so that more functions in nfssvc.c can be
called individually, and change the nfsd program to call those routines
individually.

nfssvc_setfds checks to see if knfsd is already running. Move this
check to a helper function. Eventually the nfsd code will call this
directly.

Several of the routines in nfssvc.c declare a buffer for strings. Use a
shared static buffer instead to keep it off of the stack. Also, the
buffer allocated in some places is *really* large. BUFSIZ is generally
8k. These routines don't need nearly that much.

...and add --debug and --syslog options.
With the switch to xlog(), it becomes trivial to add debug messages, so
add an option to turn them on when requested.
Also, rpc.nfsd isn't a proper daemon per-se, so it makes more sense to
log errors to stderr where possible. Usually init scripts take care of
redirecting stderr output to syslog anyway.
For those that don't, add a --syslog option that forces all output to go
to syslog instead. Note that even with this option, errors encountered
during option processing will still go to stderr.

rpc.nfsd is the only user of nfssvc.c, so we might as well move it
out of libnfs.a.
Also, don't link in libexport.a and libmisc.a, they aren't needed.
