Protocol: changes to interface and some re-implementation.

Most functions exposed in protocol.h take a connection descriptor
(cd_t) as first argument. This allows for multiple connections. Device
gets only one connection which means that cd_t is effectively 0 all
the time.

Additionaly, any function that actually does anything with a
connection descriptor instead of just passing it to another function
must be implemented separately in device and daemon.
