CRC32和CRC16校验程序C++中用DLL实现

本DLL中包含CRC32以及CRC16的校验函数，加载DLL并包含CRC.H头文件后就可在您自己的程序中自由调用CRC32或CRC16的校验函数，获取CRC校验码。资源附有CRC函数实现的源代码供参考

***  作用  ：第一，求ts流中pat，pmt表的crc32；
             第二，验证crc32是否正确，验证时，把len加4，把4个字节的crc写到
			       crc32_table的后面，得到crc为0，则crc为正确的。
     备注  : crc32_table是根据32位的crc码字得来。在vlc的开源代码中有代码。
