实现了ipv6到ipv4的转换（部分实现）

As the software is pretty simple, I've kept the build process simple as well.

For more information, please check https://sourceforge.net/projects/stfl/

COMPILE:

To build stfl on Linux or OpenBSD, simply run 'make', which will give you an 'stfl' binary in the current 
directory. For Solaris and FreeBSD, just edit Makefile to use the appropriate libraries when linking.

So far, strl has been tested on:

- Linux
- OpenBSD
- Solaris
- FreeBSD
