If the string buffers would have been overrun, set errno to EINVAL
before returning. Then, have the callers report the errors to
stderr or syslog as appropriate.

If we ended up getting a bogus string that would have overflowed, then
make key_search set errno to EINVAL before returning. The callers can
then test to see if the returned error is what was expected or something
else and handle it appropriately.

Prefer snprintf() over sprintf() in cifskey.c
Projects that fork the code (pam_cifscreds) can't rely on
the max-size parameters.

Split out some of the cifscreds key handling routines into a separate
file, and then link that in to both cifscreds and the new PAM module.
Fix up autoconf to handle building this automatically.
