Network API

[xoft]

I think the current C++ code is ready for a big review. I'd like to ask you to have a look at it, especially all the callbacks used, and say if it's okay. Testing it out would be a good idea, too - I've done tests on Win7 64-bit and on Raspbian. Before building, use this cmake command:

Code:

cmake -DSELF_TEST=1 <srcrootdir>
(or)
cmake -DSELF_TEST=1 -DCMAKE_BUILD_TYPE=Debug <srcrootdir>

This will enable the build of external tests: NameLookup, Google-exe and EchoServer. Each tests one interface of the network API - looking up IP <-> hostname, connecting as a client and downloading data, and opening a server.

@STR how's it going with WinXP, does it now work with both IPv4 and IPv6?
