Replace <term><command><arg> with <term><property><parameter> to describe

options in the config file because:
 * <arg> can only be used within <cmdsynopsis>.
 * <cmdsynopsis> does not allow text outside <command> and <arg>.
 * <arg> does not allow decorating elements like <literal> or <emphasis>.
This fixes #2803057.

Add shortcut entities for commonly used parameters (yes/no, size).
Remove Debian patch which is obsoleted by above changes.
