Fix i386 build of chpass after r363992

My change to allow bootstrapping pwd_mkdb (r363992) resulted in i386 build
failures because the bootstrap header was being included in non-bootstrap chpass.
Dropping the no longer required pwd_mkdb include path from chpass fixes
the build, but to be certain that the failure doesn't get re-introduced,
I've also moved the bootstrap pwd.h into a subdirectory so that adding
-I${SRCTOP}/usr.sbin/pwd_mkdb doesn't pull it in.

platform to test CPU affinity and NUMA-aware features in FreeBSD.

Let the afterinstall target ignore failures from running chflags. This
allows it to work over NFS, and puts it back into conformance with other
'schg' utlitilties in the system.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

Make the chpass Makefile honour NO_FSCHG.

The chpass Makefile tried to set the fschg flag on the binaries, even if
NO_FSCHG was passed to the installworld. This meant that if I installed
FreeBSD into a Jail, I couldn't installworld from within the Jail
anymore.

Now that it listens to NO_FSCHG, we can just make it bail out when it
fails, just like PRECIOUSPROG does.

Use CFLAGS, not COPTS, in the Makefile. bsd.prog.mk conveniently adds
COPTS towards the end of final CFLAGS so that it can be used to

Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

Revert the libcrypt/libmd stuff back to how it was. This should not have
happened as it was working around problems elsewhere (ie: binutils/ld
not doing the right thing according to the ELF design). libcrypt has
been adjusted to not need the runtime -lmd. It's still not quite right
(ld is supposed to work damnit) but at least it doesn't impact all the
users of libcrypt in Marcel's cross-build model.

Add libmd (or move it after libcrypt). We don't want the linker to be
smart because it will definitely get it wrong. This popped up during
cross-linking.

If an administrator somehow manages to break the hardlinks

of the proper links.

Fixed by removing the schg flag on all of the links before installing.

Add new option to chpass: -e "expire" ; change the account expire time
from a script as if it was done in the interactive editor.

When reassembling the gecos string, trim any excess trailing commas, they
look ugly in the passwd file. :-)

Have a simple Makefile tweak to prevent mortal users from changing their
fullname. As ISP's we have seem some real bizzare stuff here..

When decoding the change/expire string, allow the month number as a
synonym for the name of the month.. (ie: 1 as well as Jan or January)
Note that using numbers means there's a chance that you can get bitten
if you're not used to the American DD-MM-YY order.

Merge in changes to support the new rpc.yppasswdd(8) and fix a few bugs.

In passwd(1):

- Gut most of yp_passwd.c and leave only a few things that aren't common
to pw_yp.c.

- Add support for -d and -h flags to select domains and NIS server hosts
to use when updating NIS passwords. This allows passwd(1) to be used
for changing NIS passwords from machines that aren't configured as
NIS clients. (This is mostly to allow passwd(1) to work on NIS master
servers that aren't configured as clients -- an NIS server need not
necessarily be configured as a client itself.)

NOTE: Realize that having the ability to specify a domain and hostname
lets you use passwd(1) (and chpass(1) too) to submit update requests
to yppasswd daemons running on remote servers in remote domains which
you may not even be bound to. For example, my machine at home is not
an NIS client of the servers on the network that I manage, yet I can
easily change my password at work using my FreeBSD box at home by doing:
'passwd -d work.net.domain -h any.nis.server.on.my.net wpaul'. (Yes,
I do use securenets at work; temporarily modified my securenets file
to give my home system access.) Some people may not be too thrilled
with this idea. Those who don't like this feature can recompile passwd(1)
and chpass(1) with -DPARANOID to restrict the use of these flags to
the superuser.

(Oh, I should be adding proper securenets support to ypserv(8) and
rpc.yppasswdd(8) over the weekend.)

- Merge in changes to allow root on the NIS master server to bypass
authentication and change any user's NIS password. (The super-user
on the NIS master already has privileges to do this, but doing it
through passwd(1) is much easier than updating the maps by hand.)
Note that passwd(1) communicates with rpc.yppasswdd(8) via a UNIX
domain socket instead of via standard RPC/IP in this case.

- Update man page.

In chpass(1):

- Fix pw_yp.c to work properly in environments where NIS client
services aren't available.

- Use realloc() instead of malloc() in copy_yp_pass() and copy_local_pass().

- Fix silly bug in copy_yp_pass(); some of the members of the passwd
structure weren't being filled in correctly. (This went unnoticed
for a while since the old yppasswdd didn't allow changes to the
fields that were being botched.)

- chpass(1) now also allows the superuser on the NIS master server to
make unrestricted changes to any user's NIS password information.

- Use UNIX domain comm channel to rpc.yppasswdd(8) when run by the
superuser on the NIS master. This allows several new things:

o superuser can update an entire master.passwd.{byname,byuid} entry
o superuser can update records in arbitrary domains using -d flag to
select a domain (before you could only change the default domain)
o superuser can _add_ records to the NIS master.passwd maps, provided
rpc.yppasswdd(8) has been started with the -a flag (to do this,
the superuser must force NIS operation by specifying the -y flag
to chpass(1) along with -a, i.e. 'chpass -y -a 'foo:::::::::')

- Back out the 'chpass -a <new password entry> breaks with NIS' fix
from the last revision and fix it properly this time. The previous
revision fixed the immediate problem but broke NIS operation in
some cases.

- In edit.c, be a little more reasonable about deciding when to
prevent the shell field from being changed.

Submitted by Charles Owens <owensc@enc.edu>, who said:

"I made a minor (one-line) modification to chpass, with regards
to whether or not it allows the changing of shells. In the 2.0.5 code,
field changing follows the settings specified in the "list" structure
defined in table.c . For the shell, though, this is ignored. A quick
look in edit.c showed me why, but I don't understand why it was written as
such. The logic was

if shell is standard shell, allow changing

I changed it to

if shell changing is allowed (per table.c) and it is a standard shell
OR if uid=0, then allow changing."

Makes sense to me.

- Update man page.

Remove bogus ${DESTDIR}s from LINKS.

Keep DPADD up to date with LDADD.

bsd.prog.mk's install rule can't handle schg'ed links, so ugly
beforeinstall and afterinstall rules are required.

Take the ypchfn/ypchsh stuff that was removed from passwd
and graft it into chpass.

Chpass can now tell when it's being asked to operate on an NIS
user and it displayes the appropriate message in the editor
template ("Changing NIS information for foo"). After the changes
have been made, chpass will promte the user for his NIS password.
If the password is correct, the changes are committed to yppasswdd.

Hopefully, this should make NIS more transparent to the end user.

Note that even the superuser needs to know a user's password before
he can change any NIS information (such is the nature of yppasswdd).
Also, changes to the password field are not permitted -- that's what
yppasswd is for. (The superuser may specify a new password, but
again, he needs to know the user's original password before he can
change it.)

Missing ${DESTDIR} on chflags commands added.

Fix logic in previous commit.

Fix beforeinstall target:
use chflags /usr/bin/chpass ONLY if chpass present

Add a beforeinstall rule to turn off the immutable flag on chpass so you
can install a new copy of it.
