Extend CPPFLAGS, don't replace it

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

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

ll __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: ...

split FFS mount code out of mount(8). the correct way to name fast file
systems is now 'ffs', though 'ufs' is tolerated in fstab for backward
compatibility.

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

Move UCB-licensed code from 4-clause to 3-clause licence.

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

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

Sort sections.

Drop arguments of .Os.

Move reference to article on soft-updates from tunefs.8 to mount_ffs.8
OK'd by Ignatios.

Clean up SYNOPSIS formatting.

fix .Nx usage (use 1.0 instead of 0.9a, etc), and other minor cleanups

.Nm " " -> .Nm mount_ufs, the old name should be specifically mentioned
here.

* update for WARNS=1

Change the default for ACLs to be posix1e instead of nfsv4 to match FreeBSD.
Requested by chuq.

Add ACL support for FFS. From FreeBSD.

Implement experimental support to pass notifications that a file
was deleted from the filesystem to the disk driver, commonly
known as "discard" or "trim".
fs/driver support is in ffs and ata wd for now.
This is what was posted here:
http://mail-index.netbsd.org/tech-kern/2012/02/28/msg012813.html
with minor cleanup, and the global switch replaced by a mount option.

Use __dead

Add mount -o extattr option to enable extended attributs (corrently only
for UFS1).
Remove kernel option for EA backing store autocreation and do it by
default. Add a sysctl so that autocreated attriutr size can be modified.

Merge the simonb-wapbl branch. From the original branch commit:

Add Wasabi System's WAPBL (Write Ahead Physical Block Logging)
journaling code. Originally written by Darrin B. Jewell while
at Wasabi and updated to -current by Antti Kantee, Andy Doran,
Greg Oster and Simon Burge.

OK'd by core@, releng@.

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).

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.

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

Enable -o softdep.

Add support for a new flag: "nodevmtime". This sets the MNT_NODEVMTIME mount
flag.
