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/

Commit 409b8 introduced a regression when the --disable-tirpc
configuration flag is set. The authsys_create() interface, which
was introduced, does not exist in the legacy glibc library.
Since the authsys_create() interface is a redefined of the
authunix_create() interface, which is defined in glibc, using
authunix_create() resolves the regression,

The current mount, umount and showmount code uses
authunix_create_default to get an auth handle. The one provided by glibc
returned a truncated list of groups when there were more than 16 groups.
libtirpc however currently does an abort() in this case, which causes
the program to crash and dump core.
nfs-utils just uses these auth handles for the MNT protocol, so the
group list doesn't make a lot of difference here. Add a new function
that creates an auth handle with a supplemental gids list that consists
only of the primary gid. Have nfs-utils use that function anywhere that
it currently uses authunix_create_default. Also, have the caller
properly check for a NULL return from that function.

Introduce generic helpers for managing socket addresses. These are
general enough that they are useful for pretty much any component of
nfs-utils.
We also include the definition of nfs_sockaddr here, so it can be
shared. See:

Introduce address family-agnostic functions that get and set IP port
numbers in socket addresses. We can already replace a few similar
functions in the mount command, and a few more will come up with
statd and sm-notify.

Some RPC errors set fields in rpc_createerr.cf_error in addition
to cf_stat. Be sure to clear _all_ error fields in rpc_createerr
each time through the rpcbind API.

Instead of setting the total timeout and the retransmit timeout to the
same value for datagram transports, use a 1 second retransmit timeout,
so we actually get a retransmit or two before failing.

RPC_UNKNOWNHOST means a hostname isn't known -- basically it's
EAI_NONAME from getaddrinfo(3). Since the functions in rpc_socket.c
don't take a hostname argument, RPC_UNKNOWNHOST is not an appropriate
return code from these functions.

commit 383a026d99624c88c0e802103ef4c4865db8eb71, which fixed an
earlier commit, is still not quite correct.

There's no need to use IPV6_SUPPORTED here.

Use the correct #ifdef variable to enable IPv6 support for privileged
RPC clients. Without this fix, unmounting an IPv6 NFSv2/v3 server
fails.

We needed to guarantee that some RPC programs, such as PMAP, got an
unprivileged port, to prevent exhausting the local privileged port
space sending RPC requests that don't need such privileges.
nfs_get_rpcclient() provides that feature.
However, some RPC programs, such as MNT and UMNT, require a privileged
port. So, let's provide an additional API for this that also supports
IPv6 and setting a destination port.

Data type incompatibilities between the legacy RPC headers and the
TI-RPC headers mean we can't use libtirpc with code that was compiled
against the legacy RPC headers. The definition of rpcprog_t for
example is "unsigned long" in the legacy library, but it's "uint32_t"
for TI-RPC. On 32-bit systems, these types happen to have the same
width, but on 64-bit systems they don't, making more complex data
structures that use these types in fields ABI incompatible.
Adopt a new strategy to deal with this issue. When --enable-tirpc is
set, append "-I/usr/include/tirpc" to the compilation steps. This
should cause the compiler to grab the tirpc/ headers instead of the
legacy headers. Now, for TI-RPC builds, the TI-RPC legacy functions
and the TI-RPC headers will be used. On legacy systems, the legacy
headers and legacy glibc RPC implementation will be used.
A new ./configure option is introduced to allow system integrators to
use TI-RPC headers in some other location than /usr/include/tirpc.
/usr/include/tirpc remains the default setting for this new option.
The gssd implementation presents a few challenges, but it turns out
the gssglue library is similar to the auth_gss pieces of TI-RPC. To
avoid similar header incompatibility issues, gssd now uses libtirpc
instead of libgssglue if --enable-tirpc is specified. There may be
other issues to tackle with gssd, but for now, we just make sure it
builds with --enable-tirpc.
Note also: svc_getcaller() is a macro in both cases that points to
a sockaddr field in the svc_req structure. The legacy version points
to a sockaddr_in type field, but the TI-RPC version points to a
sockaddr_in6 type field.
rpc.mountd unconditionally casts the result of svc_getcaller() to a
sockaddr_in *. This should be OK for TI-RPC as well, since rpc.mountd
still uses legacy RPC calls (provided by glibc, or emulated by TI-RPC)
to set up its listeners, and therefore rpc.mountd callers will always
be from AF_INET addresses for now.

Instead of switching in TI-RPC-specific logic with a function-specific
switch like HAVE_CLNT_VG_CREATE, let's use the more generic
HAVE_LIBTIRPC macro everywhere.
This simplifies ./configure (always a good thing), and makes it more
clear in the source code exactly what the extra conditionally compiled
code is for.

Provide a simple interface that any component of nfs-utils can use to acquire
an RPC CLIENT *. This is an AF_INET6-enabled API, and can also handle
PF_LOCAL sockets if libtirpc is present on the system.
When libtirpc is not available, legacy RPC services will be used instead,
and an attempt to connect to an AF_INET6 address will fail.
