Mosquitto library ported to Genode

[Norman Feske]

Hi Alexander,

thank you for announcing your work on the mailing list. This is greatly
appreciated!

Have you considered to submit your port to the genode-world repository
[1]? This would make it easy to find by other community members and the
future maintenance (e.g., the adaptation to new Genode versions) could
become a joint effort.

Cheers
Norman
