 [its test][scene3][camera1]scene3/test_3a_consistency FAIL

该题原因是AE init清空m_u4Hbinwidth、m_u4Hbinheight再赋值的过程中，上层下了setAEMeteringArea()，m_u4Hbinwidth、m_u4Hbinheight为0导致Area计算错误，最终AE收敛发生变化的问题。

Its LOG一般可以看到三次的曝光设定差异太大导致的fail：

AE LOG中可以看到输入全屏的框被换算成一个点。

解决方案

在setAEMeteringArea（）中过滤m_u4Hbinwidth和m_u4Hbinheight为0的情况：

ae_mgr.cpp文件MRESULT AeMgr::setAEMeteringArea()函数中：

-              if ((sAEMeteringArea->rAreas[i].i4Right > sAEMeteringArea->rAreas[i].i4Left) && (sAEMeteringArea->rAreas[i].i4Bottom > sAEMeteringArea->rAreas[i].i4Top)){

+             if ((sAEMeteringArea->rAreas[i].i4Right > sAEMeteringArea->rAreas[i].i4Left) && (sAEMeteringArea->rAreas[i].i4Bottom > sAEMeteringArea->rAreas[i].i4Top) && ((m_u4Hbinwidth != 0) && (m_u4Hbinheight != 0))){

// Mapping AE region from Hbin size to [-1000,1000]
