logic to prevent reuse of the same code or an earlier code within the
window, and make some minor type adjustments.

Use it to control policy and module file checks. The default settings
correspond to the current behavior: disallow path separators in policy
names, but allow them in module names; verify ownership and permissions
for both policy files and modules.

string, reallocating the string if necessary.
Add an openpam_readword() function that reads a single word from a
file according to the usual shell quoting rules.
Add an openpam_readlinev() function that uses openpam_readword() to
read an entire line and return a list of the words it contained.
Rewrite openpam_parse_chain() using openpam_readlinev(), which greatly
simplifies the code and ensures correct parsing of module option.
Thanks to Maëlle Lesage for pointing out the issue and writing an
early version of what became the main loop in openpam_readword().

is currently equivalent to PAM_LOG_DEBUG, and is used only by the
library call tracing macros (ENTER*() and RETURN*()). It should
eventually replace PAM_LOG_DEBUG throughout the library, except
perhaps for a few particularly interesting messages; PAM_LOG_DEBUG
will be reserved for modules.

codes in a string with the values of selected PAM items. Use it for
prompts.
Furthermore, modify pam_get_user(3) and pam_get_authtok(3) to look for
module options named {user,authtok,oldauthtok}_prompt, as appropriate.
If found, these options take precedence over both the caller's prompt
and the PAM_{USER,AUTHTOK,OLDAUTHTOK}_PROMPT items. The usefulness of
these options is somewhat limited by the fact that the policy file
parser does not support quoted strings; that's next on the todo list.

OPENPAM_NONNULL, which may cause gcc to optimize away the NULL check.

final argument as void ** rather than const void **, but having seen
the strict aliasing warnings gcc generates at higher -O levels, it
makes a lot more sense. Change the prototype and definition back to
what the XSSO specifies, and make the necessary changes to avoid
warnings in code that calls pam_get_data().

evil global variables.
