Commit summary:

A BSD fix from Dag-Erling Smørgrav and Anton Berezin. What was there
before did not correctly deal with BSD dynamic linking.

If you are looking for an object that you can blindly dlopen() and
use to bind to pam w/ modules, this commit is for you. Its not fully
integrated into the build tree, but I'd like some feedback before
wiring it in as a regular feature.
Commit summary:
---------------
pam_unix is too generic a module to override the PAM_USER_PROMPT item.
(More modifications to xsh to help me test this change.)
Commit summary:
---------------
Added libpammodutil and link it with every module as its built.
The issue here is that there is a lot of code that the various modules
use in common, and this staic library can be used to help make this code
more maintainable. I do not intend to make this library dynamic. Especially
right now, as I want to be free to chop and change the API and don't want
to deal with revision control and third party modules.
This checkin makes the pam_rhost_auth module make some use of this new
library. I don't intend to add support for any other module prior to
releasing 0.76.
Commit summary:
---------------
The malloc debugging stuff appears to have had a few residual issues
that I've fixed (trying to resolve another checkin!).

Relevant BUGIDs: 468724
Purpose of commit: bugfix
Commit summary:
---------------
Legacy behavior for pam_close_session and pam_setcred was not sufficient.
Basically, it appears to be common practice for some applications to call
these functions without first calling pam_authenticate and pam_open_session
which would have frozen the auth and session module stacks.
The new behavior is to treat the returns of these secondary functions as
authoritative when navigating the stack in the absence of a chain-freezing
first set of calls.
pam_chauthtok should not benefit from this behavior, and there does not
appear to be a justification for using an event like this to freeze the
stack outright - legacy behavior did not do that.

The last fix to the conversation function was less than marginal: it

Also added some more D() stuff to pam_misc to help locate the problem
and finally cleaned up the Makefile in the examples/ directory. I used
xsh to do the testing.

I'm adding a new module (pam_debug) that helped me to verify that

pam_dispatch that I'll address with respect to Bug 468724.]

Purpose of commit: minor security bugfix
Commit summary:
---------------
Fixes for the password helper binaries.
Before, there was no check that the password entered was actually that
of the intended user being authenticated. Instead, the password was
checked for the requesting user. While this disstinction sounds like a
security hole, its actually not been a problem in practice. The helper
binaries have only been used in the case that the application is not
setuid-0 and as such even if an improper authentication succeeded, the
application could not change its uid from that of the requesting user.
Commit summary:
---------------
This bugfix leads to backwardly incompatable behavior with earlier
releases of Linux-PAM.
Note, this cleans up the setcred/session and chauthtok stacks in
such a way that it is no longer preferred that the setcred module
always return the same error code as the auth components of said
modules did.
This means behavior should be a great deal more sane. It also gives
meaning to the unique return codes that are available to pam_sm_setcred.
[I'm sure that when we add support for credential relevant events,
this change will be critical.]
