usr.sbin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

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.

Allow bootstrapping pwd_mkdb on Linux/macOS

We need to provide a struct passwd that is compatible with the target
system and this is not the case when cross-building from macOS/Linux.
It should also be a problem when bootstrapping for an i386 target from a
FreeBSD amd64 host since time_t does not match across those systems.
However, pwd_mkdb always truncates integer values to 32-bit so this
difference does not result in different databases.

pkgbase: Put a lot of binaries and lib in FreeBSD-runtime

All of them are needed to be able to boot to single user and be able
to repair a existing FreeBSD installation so put them directly into
FreeBSD-runtime.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

The last big commit: let usr.sbin/ use WARNS=6 by default.

- Import the HEAD csup code which is the basis for the cvsmode work.

style.Makefile(5)

WARNS=4 cleanup, de-__P()

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

- Backout botched attempt to introduce MANSECT feature.
- MAN[1-9] -> MAN.

Set the default manual section for usr.sbin/ to 8.

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.

Unifdef -DPASSWD_IGNORE_COMMENTS. This wasn't really optional and
we have enough pseudo-options already.

Allow comments in password database. The comments are copied from
the password file into /etc/master.passwd and optional (-p) into
/etc/passwd. Enable this feature with the compile
option -DPASSWD_IGNORE_COMMENTS.

The character `#' introduces a comment. Leading spaces and tabs are
ignored: '^[ \t]*#.*\n$'

Count an empty line - only spaces, tabs or newline - also as a comment.
An empty line at the bottom of /etc/master.passwd is a common
novice error and increased my mail load: '^[ \t]*\n$'

Get rid of update. Make man page installation work with our scheme
(and rename a few in the process).
