A big part of the procotol should be endian-safe (everything which goes
through the generated marshaller/demarshaller files). I expect at least
the initial connection to a channel to need some fixes
(spice_channel_recv_auth, spice_channel_send_link and similar methods).
Then I also expect more issues with the agent messages, but this needs
testing. Basically this setup (big endian <-> little endian) hasn't been
tested, so some debugging/fixing will be needed.

Patches to solve that are very welcome though ;)
