支持smil文件的MMS PDU打包方式.

mms如果不支持smil那就不能叫真正的MMS,mixed的格式对于多个附件的MMS来说不仅没有"排版"功能,

而且即使用你想一个文件一个文件"拆单了看",也不得不看一次手工播放一次,就象要手动"翻页".所以不支持

smil干脆就别玩MMS了.

但基于related格式的支持smil的PDU打包方式怎么也搜索不到,很多厂商和技术人员都故作神秘,不就是一

堆规范的实现吗?只好下了几个文档来研究,经过反复调试,其中用nowSMS的mmscomp打包出来的格式竟然

是错误的,最后多次抓包比较,总算成功了.在『别人原来的mixed方式』的基础上修改成related方式的.有需要的

就自己用去吧.(注意基础类是别人原来提供的,我只是提供了related方式的打包逻辑)
