Bigendian 奇数内存地址取整形crash

在大端机器（solaris-sparc，hpux-hppa）上从奇数内存地址取一个整形（2 or 4 bytes）会崩溃。如：

unsigned short Res = *(unsigned short *) tmpArray;

应该：

char tmpArray[sizeof(unsigned short)] = {0};
for(int i = 0; i < sizeof(unsigned short); ++i)
{
tmpArray[i] = *(pcNewHdr + i);
}

unsigned short Res =*(unsigned short *) tmpArray;
