Add HTTPS support about inadyn

[taem]

Hi,

Perhaps it is better to remove custom HTTP client code and use library like cURL? I guess many embedded device firmwares have cURL.

Not so sure about that, many have it, but not all. At work we don't.

I'd rather like to find a way to house both support for liburl and our own.

This is a hard one to crack. I guess most people will get upset if I don't chose their favorite SSL library or web crawler tool (wget/curl) ... but I'm actually looking at optional OpenSSL linking for HTTPS support.

https://github.com/openssl/openssl/blob/master/demos/ssl/cli.cpp

The code example isn't exactly bloody and if I do it right, to some extent, and wrap all necessary calls then other people can add GNU TLS support, PolarSSL support, or whatever they prefer. For me it's OpenSSL since that's what Westermo's WeOS currently has embedded in 12 MB of total (!) storage for our switches/routers. So, that's my motivation and seeing as nobody else has stepped up to the task and submitted a patch, that's what Inadyn will get :-)

It works! I added an SSL module according to the example mentioned above and have tested it successfully against DynDNS and FreeDNS :-)

Will push later today.
