libpam and / or liboath. Doing so disables building the corresponding
library and its documentation, but still builts the corresponding tools
and modules and runs the unit tests.

- move libpam into lib/libpam
- move the OATH code into lib/liboath
- move oath.h into include/security
- update all pointers

Add asprintf() and vasprintf() for systems that don't have it.

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().

OPENPAM_MODULES_DIR macro was defined in config.h in addition to
CFLAGS. Place OPENPAM_MODULES_DIR unconditionally in config.h and
remove it from CFLAGS.

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.
