Remove $FreeBSD$: one-line sh pattern

Remove /^\s*#[#!]?\s*\$FreeBSD\$.*$\n/

Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones

This implifies pathing in make/displayed output

Simplify building libpam and fix libpam.a not containing the modules since r284345.

The change in r284345 moved the creation of openpam_static_modules.o to
lib/libpam/static_modules but never managed to get them into libpam.a.

Move this logic to lib/libpam/static_libpam and have it create a static
library for libpam.a The main lib/libpam/libpam will only create a
shared library. No redundancy in compilation or installation exists
in this solution.

This avoids requiring a pass with -D_NO_LIBPAM_SO_YET.

Convert libraries to use LIBADD
While here reduce a bit overlinking

Spell NO_PROFILE= as MK_PROFILE=no.

Kill last remaining NO_INSTALLLIB in tree by converting it over to
MK_INSTALLIB=no.

Revert r227841 and part of r227798. We still build libpam in two passes,
but we use STATIC_CFLAGS instead of our own private .c.o rule.

Simplify the libpam build by removing the shared modules' dependency
on the shared library. The modules are loaded by the library, so we
know it'll be there when we need it.

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.

Remove redundant WARNS?=6 overrides and inherit the WARNS setting from
the toplevel directory.

This does not change any WARNS level and survives a make universe.

Approved by: ed (co-mentor)

Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

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

Fix build until I find a way to handle this case properly.

Revert last delta.

Comment out MK_PROFILE until ru@ can fix this properly

Convert NO_PROFILE and NO_LIB32 to new style.

NOINSTALLLIB -> NO_INSTALLLIB

NODOCCOMPRESS -> NO_DOCCOMPRESS
NOINFO -> NO_INFO
NOINFOCOMPRESS -> NO_INFOCOMPRESS
NOLINT -> NO_LINT
NOPIC -> NO_PIC
NOPROFILE -> NO_PROFILE

For variables that are only checked with defined(), don't provide
any fake value.

Make dynamic PAM modules depend on dynamic PAM library.

Requested by: des, markm

Major cleanup of bsd.lib.mk.

Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything. Added a NOINSTALLLIB knob for libpam/modules. To not
build any library at all, just do not set LIB.

Throw in NO_WERROR to please the peanut gallery.

Moved SHLIB_NAME definition into one place.

Disconnect pam_passwdqc for now, it has some issues that need resolving.

Fix build for OpenPAM. The directories needed tweeking.

Switch to OpenPAM. Bump library version. Modules are now versioned, so
applications linked with Linux-PAM will still work.
Remove pam_get_pass(); OpenPAM has pam_get_authtok().
Remove pam_prompt(); OpenPAM has pam_{,v}{error,info,prompt}().
Remove pam_set_item(3) man page as OpenPAM has its own.

WARNS=4 fixes. Protect with NO_WERROR for the modules that have
warnings that are hard to fix or that I've been asked to leave alone.

Big module cleanup.

Move common stuff into Makefile.inc, and tidy up all the Makefiles
as a result.

Build new modules.

Put a commented-out dependancy on libpam for the (shared) modules.
I can't bring this in just yet, as the dependancy (modules->libpam)
is reversed for the static case (libpam->modules).

Null file to bring back a file from the dead. This allows the real commit
to happen remotely. Damn CVS bugs :-(

Make it possible to use PAM in statically-linked applications.

Install PAM modules into ${SHLIBDIR}, not ${LIBDIR}.

Build structure for contribified Linux-PAM, plus some home-grown
modules for FreeBSD's standard authentication methods. Although
the Linux-PAM modules are present in the contrib tree, we don't
use any of them.

The main library "libpam" is composed of sources taken from three
places. First are the standard Linux-PAM libpam sources from the
contrib tree. Second are the Linux-PAM "libpam_misc" sources, also
from the contrib tree. In Linux these form a separate library.
But as Mike Smith pointed out to me, that seems pointless, so I
have combined them into the libpam library. Third are some additional
sources from the "src/lib/libpam" tree with some common functions
that make it easier to write modules. Those I wrote myself.
