Update ffsinfo(8) to use new UFS2 support in the growfs(8) debugging
functions. Largely consists of renaming fields and types to be aware
of the UFS1/UFS2 distinction, relying on libufs(3) to open and sanity
check the device/file/label accessed.
Since libufs(3) now handles label/UFS interactions, remove -L argument.
Note: when submitted, this patch had substantial style changes. I've
attempted to remove the restyling from the patch to separate the
functional and style changes.

Add support for UFS2 to the UFS debugging routines in growfs; required
to update ffsinfo(8) for UFS2. A variety of types and fs variables are
renamed to reflect UFS1/2 structures. Also, the print routines for
inodes are now split into separate UFS1 and UFS2 versions. We now
define dbg_dump_csum_total(), but lose the printing of rotational
information since that's not present in UFS2. In the future, we may
want to re-add this functionality to print it solely for UFS1.

and make it work more reliably in a number of cases that have
traditionally been troublesome. The new behaviour is:
1) If the filesystem can be determined by the fsid or device,
or uniquely identified by the mountpoint, then just go ahead
and call unmount(2) using the file system ID.
2) Otherwise use fstatfs(2) to resolve the path into a file system
ID (checking with stat(2) that it is a filesystem root directory).
Case 2 can potentially block if an NFS server is down, but it can
always be avoided by using an unambiguous specification. It handles
all the hard cases such as symlinks and mismatches between the mount
list and reality. For example, if a filesystem was mounted as /mnt
inside a chroot, it will show up in the mount list as /mnt, but now
you can unmount it from outside the chroot with "umount /chroot_path/mnt".
ID for each file system in addition to the normal information.
In umount(8), accept filesystem IDs as well as the usual device and
path names. This makes it possible to unambiguously specify which
file system is to be unmounted even when two or more file systems
share the same device and mountpoint names (e.g. NFS mounts from
the same export into different chroots).
Suggested by: Dan Nelson <dnelson@allantgroup.com>
of by mount point, umount had to take care not to unmount the wrong
file system if another file system was covering the requested one.
Now that the file system to unmount is specified to the kernel using
the filesystem ID, this confusion cannot occur, so remove the code
that checked for it.
Allow set 31 to be used for rules other than 65535.
Set 31 is still special because rules belonging to it are not deleted

This implement a flexible form of "persistent rules" which you might

* make the code compile with WARNS=5 (at least on i386), mostly
by adding 'const' specifier and replacing "void *" with "char *"

This also spotted a few places where invalid tests (e.g. uint < 0)
were used.
* support ranges in "list" and "show" commands. Now you can say
ipfw show 100-1000 4000-8000
which is very convenient when you have large rulesets.
* implement comments in ipfw commands. These are implemented in the
kernel as O_NOP commands (which always match) whose body contains
the comment string. In userland, a comment is a C++-style comment:
ipfw add allow ip from me to any // i can talk to everybody
The choice of '//' versus '#' is somewhat arbitrary, but because
the preprocessor/readfile part of ipfw used to strip away '#',
I did not want to change this behaviour.
If a rule only contains a comment
ipfw add 1000 // this rule is just a comment
then it is stored as a 'count' rule (this is also to remind
the user that scanning through a rule is expensive).
* improve handling of flags (still to be completed).
ipfw_main() was written thinking of 'one rule per ipfw invocation',
and so flags are set and never cleared. With readfile/preprocessor
support, this changes and certain flags should be reset on each
line. For the time being, only fix handling of '-a' which
differentiates the "list" and "show" commands.
* rework the preprocessor support -- ipfw_main() already had most
of the parsing code, so i have moved in there the only missing
bit (stripping away '#' and comments) and removed the parsing
from ipfw_readfile().
Also, add some more options (such as -c, -N, -S) to the readfile

system by specifying the file system ID instead of a path. Use this
by default in umount(8). This avoids the need to perform any vnode
operations to look up the mount point, so it makes it possible to
unmount a file system whose root vnode cannot be looked up (e.g.
due to a dead NFS server, or a file system that has become detached
from the hierarchy because an underlying file system was unmounted).
It also provides an unambiguous way to specify which file system is
to be unmunted.
Since the ability to unmount using a path name is retained only for
compatibility, that case now just uses a simple string comparison
of the supplied path against f_mntonname of each mounted file system.

with a new implementation that has a mostly reentrant "addchar"
routine, supports multiple message buffers in the kernel, and hides
the implementation details from callers.
The new code uses a kind of sequence number to represend the current
read and write positions in the buffer. This approach (suggested
mainly by bde) permits the read and write pointers to be maintained
separately, which reduces the number of atomic operations that are
required. The "mostly reentrant" above refers to the way that while
it is now always safe to have any number of concurrent writers,
readers could see the message buffer after a writer has advanced
the pointers but before it has witten the new character.

assumption. However, in recent years we have begun seeing
devices with 2048-byte sectors. These devices return errors
when dump tries to read starting in the middle of a sector
or when it tries to read only the first half of a sector.
Rather than change the native block size used by dump (and
thus create an incompatible dump format), this fix checks
for transfer requests that start and/or end on a non-sector
boundary. When such a read is detected, the new code reads
the entire sector and copies out just the part that dump
