mdoc: drop redundant .Pp and .LP calls

They have no effect when coming in pairs, or before .Bl/.Bd

Make chflags(1) more chmod(1)-like (and more feature complete):

- Add -v to print file names as they are processed; -vv prints the flags
change as well.
- Add -f to ignore failures with the same semantics as chflags(1), neither
printing an error nor affecting the return code.
- Don't try to set the flags if they won't change.

I made minor cosmetic tweaks to the code in the patch.

Fix probably copy&paste from chmod(1) - we change file flags here, not mode.

Use .Cm for all key words, not just the ones I added. More in line with
mdoc(7) according to ru.

Requested by: ru

Slightly better markup.

Discussed with: ru

Instead of just hinting at available octets, list some.
Mention that the setting of securelevel may affect one's ability to alter flags.
Xref security.7.
Bump doc date.

Sort sections.

Approved by: re (blanket)

Add an interface to the lchflags(2) syscall. The new -h option is
analogous to chmod(1)'s -h. It allows setting flags on symbolic links,
which *do* exist in 5.x+ despite a claim to the contrary in the
chflags(1) man page.

Suggested by: Chris Dillon

Fix a few markup nits in previous commit.

Noticed by: ru, who else? :)

Add information on utilities which may or may not be aware of file flags.

Add the new standard EXIT STATUS section where appropriate.
Sort standard sections in the (documented) preferred order.

mdoc(7) police: Fix document date.

Document how to clear flags with negative-logic, currently only
the nodump flag.

chflags(1) repo copied, usr.bin->bin.
We've been installing chflags(1) into /bin since 2000-11-10, so this
shouldn't cause any problems.

mdoc(7) police: utilize the new .Ex macro.

Make it clear that -P is the default.

PR: docs/27629

Prepare for mdoc(7)NG.

mdoc(7) police: use the new features of the Nm macro.

Document that the flags can be specified as an octal number.

Correct use of .Nm. Add DIAGNOSTICS section. Add rcsid

Yet another previously forgotten merge from Lite2. (Describe
`opaque', fix reversed description of `nodump', and don't use
`nodump' as an example of adding a `no' prefix since the double
negative would be confusing (it's still confusing -- the implicitly
documented `nonodump' flag doesn't exist).)

$Id$ -> $FreeBSD$

Document the use of `ls -lo' to see flags.

These changes add the ability to specify that a UFS file/directory
cannot be unlinked. This is basically a scaled back version
of the IMMUTABLE flag. The reason is to allow an administrator
to create a directory hierarchy that a group of users
can arbitrarily add/delete files from, but that the hierarchy
itself is safe from removal by them.
If the NOUNLINK definition is set to 0
then this results in no change to what happens normally.
(and results in identical binary (in the kernel)).
It can be proven that if this bit is never set by the admin,
no new behaviour is introduced..
Several "good idea" comments from reviewers plus one grumble
about creeping featurism.

This code is in production in 2.2 based systems

Use the .Bx macro in the HISTORY section.

Add history section. Follows chflags(2).

Document the arch flag. It has always worked in 2.0.

Document aliases for the flags.

The formatting of the section describing the flags is poor.
