乌龟服debuff数量上限及判断方法

WoW1.12香草版本的debuff上限是16个，乌龟服服务器端进行了魔改，先改到24个，又改到了64个，但目前各类插件均只能显示16个debuff。

The debuff limit was increased from 24 to 64. You will not see them all under your enemy frame, but they're there server-side.
debuff上限从24增加到了64，部分debuff你看不到，但服务器端认。
Debuffs 1-16 show as "debuffs" you can get them with UnitDebuff
Debuffs 17-48 show as "buffs" so you can get them with UnitBuff
49 to 64 are invisible and unable to see by the player
