From 12dce46d611d6ea7c772174ebbd555fa10fead99 Mon Sep 17 00:00:00 2001
From: Haru <haru@dotalux.com>

Subject: Sanitized and improved several macros through the code

- Sanitized all potentially unsafe macros (related eA:15259)
- Improved some function-like macros to evaluate their argument only
  once and keep it in a temporary variable.  This improves performance
  in the damage calculation related code.
