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
PAM_SYSTEM_ERR, since this is a programmatical error rather than
a runtime one.

detect and prevent indirect recursion.
Fail immediately if the requested chain is empty.
If a module couldn't be loaded, or doesn't provide the requested
service, treat it as a normal failure instead of terminating the
chain. (Solaris actually ignores this condition!)
