SIM卡设置里面关闭一张卡时如何自动将默认数据，通话，短信切换到另一张卡

[DESCRIPTION]
双卡项目中很多客户希望在关闭一张卡时，自动将默认的数据，通话，短信切换到另一张卡上。
[SOLUTION]
在SIMSettings里关闭一张卡的时候，会调用到DefaultSIMmanagementExt.java文件的
setToClosedSimSlot函数，默认代码这里是空，因此不会做切换，如果客户想要客制化此功能的话，请作如下
修改：
在默认的空函数中添加代码，客户可根据自身项目需要里面三个函数中的任意一个或多个。但是默认通话功能切换对
应的函数有三个，还请注意。
public void setToClosedSimSlot(int simSlot) {
Xlog.d(TAG, "setToClosedSimSlot = " + simSlot);
setToChangeDefaultData(simSlot);
setToChangeDefaultVoice(simSlot);
setToChangeDefaultSMS(simSlot);
}
setToClosedSimSlot
改变默认数据
