Follow-up for c3b3eea. Addresses systemd#39826 (comment).
- pam_log_oom() passes ENOMEM rather than -ENOMEM, hence previously pam_log_oom() did not return PAM_BUF_ERR. - We may (mistakenly) pass SYNTHETIC_ERRNO(). Let's gracefully handle that. - Introduce errno_to_pam_error() helper function.
Currently, the result of pam_debug_syslog_errno() is unused, hence this does not change anything and may be slightly redundant. But let's follow our usual coding style.
- Do not use '%m' when errno is not set. - Do not use pam_syslog_errno() when errno is not set. - Use pam_debug_syslog_errno() rather than log_debug_errno(). - Use 0 rather than PAM_SUCCESS in the function that returns negative errno, though PAM_SUCCESS == 0, hence that does not change any behavior. - Append missing full stop in the log message.
