Create the concept of a "failed authentication" as semantically

separate from a successful or failed login.

1) Rename user_login_failed event to user_authenticate_failed

2) Rename failed_logins table to failed_auth (bump Gallery module to
   v27 to rename the table)

3) auth::too_many_failed_logins -> auth::too_many_failures

4) auth::record_failed_auth_attempts -> auth::record_failed_attempts
   auth::clear_failed_auth_attempts  -> auth::clear_failed_attempts
