Find an implementation of HTTP that could be used in Renode

[PiotrZierhoffer]

To implement the HTTP support, we need the to have the HTTP server.

We can

a) implement it ourselves
b) find an implementation and use it
c) use something that's built in the framework

Implementing it ourselves would be, in my opinion, too much work. We don't need fancy features, but the HTTP protocol is big by itself.

We could use something from the framework, but I don't know what's available on both Mono and .NET.

External library has to have a permissive license (Apache, MIT etc).

It needs to compile well on Mono and .NET Framework and should not rely on external software.
It should also be configurable from code, not config files.

Please note all candidates you're investigating in this issue (along with the decision and its justification).
