[mosquitto-dev] Github repository move

[Roger Light <roger@xxxxxxxxxx>]

Dear all,

The mosquitto repository has moved locations to
https://github.com/eclipse-mosquitto/mosquitto

This puts the project in its own organisation and makes it easier for
Eclipse and ultimately us to manage.

There is an automatic redirect in place from the old location, but
please update your bookmarks or equivalent.

Regards,

Roger
