Fixing multi-session disc mount by passing the correct "ssector" option
to the kernel.

Submitted by: Enache Adrian <enache at rdslink dot ro>

It turns out that set_charset() invokes build_iovec() which modifies
iov address internally through realloc(3). However, since the function
parameter wasn't designed to allow the modified iov being passed back to
the caller, we end up feeding iov with several corrupted entries(depends on
how many arguments were pushed into iovec before set_charset()) to nmount(2).

This commit fixes this regression introduced in rev1.31 such that
mount_cd9660(8) with code page conversion option(-C) enabled works again.

Convert mount_cd9660 to use nmount().

Use MOPT_END in favor of MOPT_NULL, which better describes the purporse
of the macro.

Add a handy macro to represent null mount option, MOPT_NULL, and make
use of the macro in sbin/mount*'s, by replacing:

mopts[] = {
MOPT_STDOPTS,
{ NULL }
}

With:
mopts[] = {
MOPT_STDOPTS,
MOPT_NULL
}

This change will help to reduce the situation that we don't explicitly
initialize "struct mntopt"'s. It should not contribute to any
functional/logical changes as far as I can tell.

This should have been committed too, I have no idea
why p4 didn't gave me this diff too.

Now that the kernel is able to load modules itself,
remove all the code which was trying to do so.
This code was nasty in several ways, it was hiding
the kernel bug where the kernel was unable to properly
load a module, and it was quitting if it wasn't able
to load the module. The consequence is that an ABI
breakage of the vfsconf API would have broken *every*
mount utility.

o Move NTOHL() and associated macros into <sys/param.h>. These are

o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

Userland part of ISO9660 multi-session support. mount_cd9660(8) will
now by default mount the last data track (thus last session), as
opposed to the very first session it has been mounting previously.
This is consistent with the ISO9660 multi-session idea, and the way
other operating systems are working.

There's support to mount arbitrary sessions using the -s option. This
way, you can simulate multi-session CDs on something like vn devices
that don't support CDIO* ioctl commands. You can also force the
historic behaviour with

mount -t cd9660 -o -s=0 /dev/cd0a /cdrom

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Get rid of the last vestiges of the old MOUNT_* constants in the
mount_* programs. While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].

Also, convert the mount programs to use sysexits.h.

Include the special device in the error output so that it makes sense.

Add support for filesystem-specific `-o' options, and re-implement the
most common cd9660 and nfs options like God intended them. (It is now
possible to say

mount -o ro,soft,bg,intr there:/foo/bar /foo/bar

again.) This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3). Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.

(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)

Automatically load NFS and a bevy of other filesystems.

Get rid of the need for the readonly mandatory option - set readonly
flags regardless of whether the user specified it.

Don't call getmntopts with a null pointer as an option string; it'll
dereference it. Pass optarg from getopts as it should have been done.
This bug caused mount_cd9660 to segfault whenever -o was used.
