zsync 0.5

The main feature of this release is that large file support is now enabled on
systems (Linux/i386 in particular) where it needs to be explicitely selected.
As I do most of the development on Linux/x86_64 now, I was blissfully ignorant
of this problem until Robert Lemmen forwarded a complaint about it.


I have also fixed some compilation problems to MacOS X and Solaris. There is also a substitute for getaddrinfo provided for systems that need it, which someone emailed me about.

Finally, I have made the source code repository for zsync available online.
This, and the new release, are available from the download page.
