Refactor remaining mount_* commands to use the common pathadj()
function for resolving paths.

Make pathadj() no longer warn about symlinks. Symlinks in /dev are
regularly used in several places like LVM . The warning was also
only visible when calling a mount_* command directly as mount(8)
itself would resolve the path witout warning before passing it to
a mount_* command.

Move WARNS=3 to the Makefile.inc, and add a little const to the remaining
programs that did not compile before.

Kill __P(), use ANSI function declarations; WARNS=3.

move getmntopts(3) to libutil, build and install also it's manpage
bump libutil minor
adjust individual mount_*/Makefile to use libutil getmntopts(3)

MNT_GETARGS support

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path

make the code includable into other programs:
* make static all symbols which do not need to be exported
* rename main() to mount_FOO()
* new main() now just calls mount_FOO(), main() is only compiled in if
MOUNT_NOMAIN is not defined
* a_gid(), a_uid() and a_mask() were put into ../mount/fattr.[ch], local
versions removed

Add man page for mount_filecore.

Initial commit of mount_filecore used for mounting filecorefs partitions.

Fix PR#3617 and PR#3205: call realpath to convert mount points and paths to
device nodes into absolute paths before using them.

Sort options; bump date.

.Nm does not need a dummy argument ("") before punctuation or

Fix tyops pointed out by Igor Sobrado in PR misc/19623:

mount_filecore(8) - frquently (frequently), upto (up to)
mount_nfs(8) - NFSV3 (NFSv3), automaticly (automatically)
mount_ntfs(8) - particularily (particularly), fisk (disk)

New sentence, new line. By Robert Elz with minimal fixes.

Punctuation nit.

Drop arguments of .Os.

Use __dead

Refactor mount utilities to provide a mount_fs_parseargs() routine.
Use this routine both in mount_fs and rump_fs to provide equivalent
command line parameters and therefore usage interchangeability.
While doing this, combine some common mountgoop to mountprog.h

Remove the \n and tabs from the __COPYRIGHT() strings.
(Tweak some to use a consistent format.)

Make all mount(2) return value error checks against -1. Some file
systems just checked != 0, breaking MNT_GETARGS. Others worked with < 0,
but make them check against -1 too for consistency. And sprinkle some
stylish line wrapping where appropriate.

Add additional 'sizeof args' parameter to mount(2).

- removes unused ctype.h header
- correct comment in mount_nfs/getnfsargs.c: s/Nead/Need/

From: Slava Semushin <php-coder@altlinux.ru>

use MOPT_NULL

Always check the results of getmntopts() and free them.

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
file sys/nfs/nfs_export.c. The former was becoming large and its code
is always compiled, regardless of the build options. Using the latter,
the code is only compiled in when NFSSERVER is enabled. While doing this,
also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
path and a set of export entries. At the moment it can only clear the
exports list or append entries, one by one, but it is done in a way that
allows setting the whole set of entries atomically in the future (see the
comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
that it becomes file system agnostic. In fact, all this whole thing was
done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
exports initialization; done internally by the kernel when initializing
the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
subsystems can run arbitrary code upon receipt of specific VFS events.
At the moment, this only provides support for unmount and is used to
destroy NFS exports lists from the file systems being unmounted, though it
has room for extension.
