Problem:
=======
The ALWAYS option of the mariadb-binlog --base64-output flag
formats its output incorrectly. This option is deprecated, and
MySQL 8.0 has removed it entirely.
Solution:
========
Adhere to MySQL and remove this option from MariaDB.
Behavioral Changes:
==================
Use Case: ./mariadb-binlog --base64-output
Previous Behavior: Sets base64-output mode to always
New Behavior: Error message indicating incomplete argument
Use Case: ./mariadb-binlog --base64-output=always
Previous Behavior: Sets base64-output mode to always
New Behavior: Error message indicating invalid argument value
