Awesome!

We use gitlab for development in the meantime and have a complete CI running:

https://gitlab.com/libssh/libssh-mirror/

All new stuff needs to come with tests! Untested code is broken code :-)

I'm adding Tilo as he is probably also interested in that API. He also started 
to look into it iirc.


How it should look like I'm not 100% sure, but maybe we should model it after 
liburing, which is the new hip async IO interface of the Kernel.

Yeah, the current API is not nice at all. I'm open for suggestions for the 
current API.
