Backport upstream r684 (OPENPAM_DEBUG enables debugging macros but does
not turn debugging on by default) and add OPENPAM_DEBUG to CFLAGS.

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.

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.

Bump the version of all non-symbol-versioned shared libraries in

Update for OpenPAM Figwort.

Approved by: re (kensmith)

Add -DDEBUG to DEBUG_FLAGS if PAM_DEBUG is defined.

Deal better with the crypto version of the PAM library that goes
on the release media -- only put what is different in the crypto
version compared to the base version. This reduces PAM entries
in /usr/lib in the "crypto" distribution to:

libpam.a
libpam.so@
libpam.so.2
pam_krb5.so@
pam_krb5.so.2
pam_ksu.so@
pam_ksu.so.2
pam_ssh.so@
pam_ssh.so.2

The libpam.so* is still redundant (it is identical to the "base"
version), but we can't set DISTRIBUTION differently for libpam.a
and libpam.so.

(The removal of libpam.so* from the crypto distribution could be
addressed by the release/scripts/crypto-make.sh script, but then
we'd also need to remove redundant PAM headers, and I'm not sure
this is worth a hassle.)

DISTRIBUTION is normally single-valued.

Trasmute moer "krb5" distibutions into "crypto".

Remove commented-out WARNS thingy.

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.

Comment out the WARNS= so as to not trample all over the GCC3 work.

Turn on fascist warning mode.

Making this major bump was a BAD idea. The API change is internal (to PAM)
and it caused problems without solving any.

Bump the major number. The libraries API has changed incompatibly.

This commit was generated by cvs2svn to compensate for changes in r41227,

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.
