I think we can simplify the use of getaddrinfo(3) so that only one
call is needed to gather both IPv4 and IPv6 addresses. The call
should fail, and an error should be reported, only when there are
_no_ addresses bound to a hostname.

As nfsd establishes UDP and TCP ports, it should establish RDMA too.

This implementation allows specifying NFS4 minor version numbers up
to the number of bits available in int data type (typically 32 on
Linux)
This is based on an idea mentioned by
J. Bruce Fields <bfields@fieldses.org> mentioned on the linux-nfs mailing list.
I changed the data type back from an array to two bit fields, one for
storing whether the minor version was specified on the command line
and the second one for storing whether it was set or unset. This
change was done to prevent blowing up the allocated stack space in an
unnecessary fashion.

From: "J. Bruce Fields" <bfields@redhat.com>
By unconditionally adding ?4.2 to the version string written to the
kernel we make nfs-utils incompatible with pre-4.2-supporting kernels.
Ditto for 4.1. This problem was introduced by
12a590f8d556c00a9502eeebaa763d906222d521 "rpc.nfsd: Allow v4.2 server
support with the -V option", which also change nfsd to unconditionally
pass ?4.2.
Instead, just don't mention 4.1 or 4.2 unless the commandline has
specifically requested that one or the other be turned on or off.

License texts contain multiple address for FSF, some wrong.
So update them and replace COPYING file with
http://www.gnu.org/licenses/gpl-2.0.txt
which has a few changes to preamble and commentary.
Also remove extra COPYING file from utils/statd/

There's a bit of a chicken and egg problem when nfsd is run the first
time. On Fedora/RHEL at least, /proc/fs/nfsd is mounted up whenever nfsd
is plugged in via a modprobe.conf "install" directive.
If someone runs rpc.nfsd without plugging in nfsd.ko first,
/proc/fs/nfsd won't be mounted and rpc.nfsd will end up using the legacy
nfsctl interface. After that, nfsd will be plugged in and subsequent
rpc.nfsd invocations will use that instead.
This is a problem as some nfsd command-line options are ignored when the
legacy interface is used. It'll also be a problem for people who want
IPv6 enabled servers. The upshot is that we really don't want to use the
legacy interface unless there is no other option.
To avoid this situation, have rpc.nfsd check to see if the "threads"
file is already present. If it's not, then make an attempt to mount
/proc/fs/nfsd. This is a "best-effort" sort of thing, however so we
just ignore the return code from the mount attempt and fall back to
using nfsctl() if it fails.

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.

They are a little hard to follow currently. Clean them up and add new
macros that can set these bits in addition to the ones that unset them.
Also add a new macro that reports when any valid protocol bit is set.
