SndWorker has been historically based on RedChannel, initial git commit
has:
struct SndWorker {
Channel base;
...
};
SndChannel, contrary to what its name may imply is more focused on
marshalling/sending of sound data, which is the responsibility of
RedChannelClient for the other SPICE channels.
This commit and following ones make the naming of these 2 types more
consistent with how the rest of the code is structured.
