[Spice-devel] [RFC v4 07/62] server/main_channel: use MainChannel in sig

We have these various channel types for main_channel_foo()
argument/return value, would be nice to make some changes:

- Channel *main_channel_init()

reds->main_channel_factory = main_channel_init();

Should we rename main_channel_init() to main_channel_factory_new()?
and perhaps rename Channel to ChannelFactory?

- RedChannelClient *main_channel_link(struct Channel *,..)

rcc = main_channel_link(reds->main_channel_factory,..)
reds->main_channel = (MainChannel*)rcc->channel;

I think we could have this instead (correct prefix, return proper
type, better naming):

reds->main_channel = main_channel_factory_build();

- void main_channel_close(MainChannel *main_chan);

this one is good!

- void main_channel_push_init(RedChannelClient *rcc,...)

Wouldn't it be more sensible if the main_channel_foo() with
RedChannelClient* take a MainChannel* instead?

But this seems to be fixed in a later patch
