DNS SD doesn't work on Windows

[rgetz]

As discussed in #388 - we don't support Win32 yet.

https://github.com/stammen/dnssd-uwp
has enough to make sure that Win10 would be supported (which I think is OK).

That would use these built in win10 features:

I made a pull request #412 - let me know if we should merge that as is, or if you think you will have time to look at adding windows 10 support before then.

I guess the steps would be to create a dns_sd_win10.c, this would include things like:

• a test for win10
• dynamically load the dnssd-uwp DLL using LoadLibrary() & get pointers to the various dnssd functions
• Create a dnssd service watcher using the above function
• Which calls your callback which builds up the linked list, like the avahi and bonjour implementations do.
• free everything when done.

I think that should be it. All the above code is under a MIT license - which means we can include it into libiio, we just need to point back, and make sure to include the appropriate copyrights in it.

Would it make sense to use an independent implementation like:

Would it make sense to use an independent implementation like:

I don't think so - as much as it pains me - I don't think adding another library is worth it.

This is being worked on as part of #508 , so closing this, as that (hopefully) will be merged soon.
