Before this commit, the code relied on
spice_main_channel_update_display() called from the client application
to add items to the list of monitor_configs to be sent to the server
(stored in SpiceMainChannelPrivate.display). One of the disadvantages
this approach has is that all data that you need in the list have to go
through the client application. Thus adding any attribute to a
monitor_config requires an API change.
This commit changes this by creating and maintaining our own list of
monitor_configs under the session object. The methods that are exposed
to the client app no longer create new items in this list.
Now the spice_main_channel_update_display{,_enabled}() functions only
update existing items in the spice-gtk-maintained list. The identifier
for these functions was unfortunately the index in the array on the
spice-gtk side and channel_id + monitor_id in e.g. virt-viewer. This
worked under the assumption that there is either only one display
channel or multiple display channels each with only one monitor.
Presumably other clients can use whatever they like as the id, but doing
something else most probably wouldn't work.
So, we use the channel_id + monitor_id in the now-deprecated
spice_main_channel_update_display{,_enabled}() to match against their
single 'id' argument. This works for as long as the assumption mentioned
above holds true, which doesn't for the guest streaming use case
anymore. So for that use case a new client is needed using the new
consistent API.
An unsorted list is used and the items are looked up by simple
iteration. No more than 5 items are really expected in the list. The
order of the items in the list is determined by their creation timing
and therefore is undeterministic. The order should no longer matter for
anything though.
