- When loading a versioned module, store its logical name in the

Replace the "dispatching" flag with a pam_chain_t pointer. It is set
to point at the currently executing module right before calling the
module, and cleared right after the module returns. Note that this
isn't intended to prevent reentrancy in multi-threaded applications,
but simply to prevent modules from using the application interface.
When recursion is detected, return PAM_ABORT rather than
