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)

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

CFLAGS->CPPFLAGS

Back out the .PATH.c changes. The .depend problem (and others)
will be fixed using the new .NOPATH make feature instead.

Use .PATH.c: ...

.Nm does not need a dummy argument ("") before punctuation or
for correct formatting of the SYNOPSIS any longer.

Sort sections, use standard section headers.

Whitespace nits

Drop arguments of .Os.

Clean up SYNOPSIS formatting.

macroize BSD, NetBSD, FreeBSD and misc cleanup

* update for WARNS=1
* getopt returns -1 not EOF
* fix .Nm usage

fdescfs now provides . and .. entries, so remove the comment about
them not being there.

slightly clean rcs ids, etc.

after things settle down, i've decided that these should be broken
out into their component programs again; combining them was a mistake...

Use __dead

initialize canon_dev

convert to parseargs form

Shortcircuit -o getargs in userspace. We know the kernel driver
will not return any data and mount(2) fails with EINVAL if data_len
is 0. This caused lame-o output in mount -vv:
mount_fdesc: fdesc on /failsystem: Invalid argument

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

branches: 1.21.12; 1.21.16;
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).

use MOPT_NULL

c99 initializer

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

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

use <> rather than "" for #include mntopts.h

MNT_GETARGS support

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

Regularize error reporting of mount_* commands for failure of mount(2)
to the form:

mount_xxx: dev on dir: reason for failure
