libpam-base-files: Start to add default config files for libpam

* This will start to get Linux-PAM into a usable state. Default config files derived from Debian with tweaks. Some are not needed and will be dropped later and some should really be packaged elsewhere.
* Also update libpam_1.0.2 to depend on this package and the meta package with auth systems as it is not a lot of use without them (it works but can't do anything).
* Add 1.1.0 and tweaks to 1.0.2.
*  Update all the pam.d base config files to support the suggested upstream layout not patches legacy layouts used but some Linux distros.
* Use the proper include layouts
* Still package some 'suggested' files for common services that do not pack there own pam.d files (TODO: move these to the package recipies not this one).

+# /etc/pam.d/common-password - password-related modules common to all services
+#
+# This file is included from other service-specific PAM config files,
+# and should contain a list of modules that define the services to be
+# used to change user passwords.  The default is pam_unix.
+
+# Explanation of pam_unix options:
+#
+# The "sha512" option enables salted SHA512 passwords.  Without this option,
+# the default is Unix crypt.  Prior releases used the option "md5".
+#
+# The "obscure" option replaces the old `OBSCURE_CHECKS_ENAB' option in
+# login.defs.
+#
+# See the pam_unix manpage for other options.
+
+# here are the per-package modules (the "Primary" block)
+password	[success=1 default=ignore]	pam_unix.so obscure sha512
+# here's the fallback if no module succeeds
+password	requisite			pam_deny.so
+# prime the stack with a positive return value if there isn't one already;
+# this avoids us returning an error just because nothing sets a success code
+# since the modules above will each just jump around
+password	required			pam_permit.so
+# and here are more per-package modules (the "Additional" block)
+password	optional	pam_gnome_keyring.so
