Update to Neat VNC 1.0.0 and aml 1.0.0, which promise stable API.
Adapt to API changes:
- authentication API now wraps username/password into
credentials and can be asynchronous
- userdata get/setters are now type specific
- fbs have been renamed to frames, storing dimensions and damage
- nvnc_open() is split into nvnc_new() and nvnc_listen_tcp()
- nvnc_close() is now nvnc_del()
