mount_nfs.c: Add an NFS mount option to set a port# for Mount

Normally mount_nfs acquires the port# for the NFS server's
Mount protocol (mountd(8)) via rpcbind/portmapper for
NFSv3 mounts.

This patch adds a new mount option, so that the mount
command can specify the port# and avoid using rpcbind
for NFSv3 mounts.

The new option is called "mountport" since that is what Linux
calls their mount option for the same semantics.

We've ifdef'd out the copyright strings for some time now. Go ahead and

are largely from CSRG's attempt at adding their copyright to every
binary file (which modern interpretations of the license doesn't
require).

mount_nfs: Warn that intr, soft are not safe for NFSv4

If the "intr" and/or "soft" mount options are used for
NFSv4 mounts, the protocol can be broken when the
operation returns without waiting for the RPC reply.
The likelyhood of failure increases for NFSv4.1/4.2
mounts, since the session slot will be broken when
an RPC reply is not processed.

This is mentioned in the BUGS section of "man mount_nfs",
but more needs to be done. This patch adds code that
generates a warning message when the mount is done.

mount_nfs: Only create a mounttab file entry is nmount(2) succeeds

mount_nfs creates entries in the mounttab file and umount removes
them. Entries in the mounttab file ae used by rpc.umntall to
notify the NFS server that NFSv3 entries need to be removed when
they have not been removed by umount.

Without this patch, an enty will be created in the mounttab file,
even if the nmount(2) syscall fails for the mount. This patch
modifies the code so that the mounttab entry is only created
after nmount(2) succeeds.

This change only affects NFSv3 and only affects how showmount
displays NFSv3 mounts.

When a machine boots the NFS mounting script is executed after
interfaces are configured, but for many interfaces (e.g. all Intel)
ifconfig causes link renegotiation, so the first attempt to mount
NFS always fails. After that mount_nfs sleeps for 30 seconds, while
only a couple seconds are actually required for interface to get up.

Instead of sleeping, do select(2) on routing socket and check if
some interface became UP and in this case retry immediately.

Fix mount_nfs to recognize the NFSv4 specific errors returned by nmount(2).

When mount_nfs calls nmount(2), certain NFSv4 specific errors such as
NFSERR_MINORVERMISMATCH can be returned.
Without this patch, 10021 is reported as an unknown error.
This is not particulcarily serious, but make it difficult for sysadmins
to figure out why the mount attempt is failing.
This patch uses nfsv4_errstr.h to convert 10021 and similar to error strings
that can be printed out.
A positive side effect of this patch is the removal of a reference to
sys/nfsclient/nfs.h, which should no longer be used, since it is
part of the old NFS client.

This patch should only affect reporting of failed mount attempts and not the
semantics of NFS mount attempts.

General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
