打造世界最小LZMA解压DLL（第二弹）

一年前我曾写过一篇《手写PE文件，打造史上最小LZMA解压DLL》，最近因为涉及毕业设计，重新开始研究PE，同时也需要提供LZMA压缩功能。

对原来的程序观察后发现，UPX使用的LZMA代码并不是最优化的编译，原因是局部变量全部使用ESP寻址，而Intel x86对寄存器寻址有个ESP例外，需要多占用一字节的指令。于是重新翻出LZMA SDK，使用VC6编译出2409字节的代码（原来是2694字节）。

另外一个问题就是原来开头写的sub esp, 3e80是不对的。Windows分页机制规定，栈分配是逐页进行的，当当前栈位于页顶端时访问上面的页会引发栈空间分配，但跨页访问即认为访问越界。显然3e80可能会造成跨页访问导致程序崩溃。

这次最终的DLL文件是2970字节，缩小至原来的90%。

这次先贴代码，DLL文件以后再更新后发，因为看上去可以通过修改SDK使文件更精简。
