Recently #include directives for autoconf's config.h file were added in
utils/mount/error.c and utils/mount/mount.c, but appropriate HAVE_CONFIG_H
checks were not added at the same time.
In addition, several other .c files under utils/mount reference
autoconf-generated HAVE_ macros, but don't appear to include config.h
Also, Heinz-Ado Arnolds <arnolds@MPA-Garching.MPG.DE> reports that this
patch is needed to ensure START_STATD is properly defined in
utils/mount/network.c. Otherwise start_statd() is always a no-op, even if
the configure script defines an appropriate statd start-up script.

The mount(5) man page states that the noquota, quota, usrquota and
grpquota options are ignored. (They are, however, used by the quota
tools, so having them in fstab can be useful.) Make mount.nfs ignore
them properly, matching the man page. There are a few aliases (like
usrjquota) that are parsed by quota, but as these are not documented
nor seem to be widely used, they are not included.

In mountd, if get_exportlist() (utils/mountd/mountd.c) returns NULL it
should not be considered a failure. It just means that there are no
exports on the system.
The practical problem with the current code is that a showmount -e
results in a syslog message from mountd that looks like:
rpc.mountd: export request from 10.250.100.2 failed.

Address an inconsistency: the mount.nfs command uses the glibc routines
to manipulate /etc/mtab (setmntent) but, everything else in nfs-utils
uses a local private version (nfs_setmntent). The local version does
some extra mangling of the mtab entries.
We should check what util-linux does these days to be sure, but for now,
let's make the mount.nfs command use the nfs_ variants of setmntent().

When mountd gets a request to export a mountpoint which is not
explicitly exported, but is below an export point that is flagged as
"crossmnt", it passes the wrong path name to the kernel for the
"filehandle -> directory"
mapping.
This can badly confuse the NFS client, and is certainly wrong.
So use the correct path names.

When following a list of mount versions to probe -
e.g. probe_mnt1_first or probe_mnt3_first - probe_both will first
probe the appropriate NFS version and then, if that succeeds, probe
the actual mount version. However instead of probing the target mount
version, it probes the "most appropriate" mount version for the given NFS version.
This results in it probing:
NFSv2, MOUNTv1
twice rather than
NFSv2, MOUNTv1
NFSv2, MOUNTv2
as would be more correct.
This patch removes the "choose most correct" step and just use the
current mouint version for the probe_vers array.

This means that if mountd is run with "--no-nfs-version 3",
It will first probe for NFS version 3, which will succeed (assuming the
kernel supported NFSv3), then it will check the matching mountd version (3)
and probe_port on discovering that isn't supported will try other versions,
find "1" is supported will succeed.
This leaves up using mount version 1 for an NFSv3 mount, which doesn't work
and leads to a SIGSEGV
There is no case where trying other versions is needed the request one is
not supported, so simply remove that code.

It would be cleaner to use a single enum for po_rightmost()'s return value.
We take the next logical step and create specific types for the return

Fix version fallback for unmount.
Previously, if the mtab record didn't mention a version, unmount
would assume a v3 umount and send an UNMOUNT request accordingly.
This is wrong.
So remove the 'v3' assumption, and allow probe_port to continue when
it gets a version number mis-match.
Also there was some overloading of the meaning of pm_vers==0 relating
to v4 mounts. As do_nfs_umount is never called for v4, rename it to
do_nfs_umount23, and remove v4 handling from there and from
nfs_call_umount.
