Same or derivate project can be loaded in more than one room. This will cause more than one port
with given uuid to be added to the jack graph. This changeset uses vgraph-port_uuid pair when searching
for port that was added at earlier project load stage. For this to work, when ports are created and added
to the jack graph, the vgraph handle is stored in the port object.
The room link ports were searched by uuid gloablly.
When two rooms had same ports uuid, always the first one was found.
Then when setting the graph override uuid for port, the port
override uuid of the second room was set over the port of the first
room. Thus the first room port was getting wrong override uuid and the
second room port override uuid was never set.
The solution implemented is to search for the port within the already
found room client. Then set the override uuid for the found port.
Room client in the studio graph has uuid of the room and is created
when room is loaded. This ensures that later when room-link ports are
added, the port of the right room client will be found. Then the
override uuid will be set to the proper port.
* Helper functions in daemon/save.c will be used in project save functionality as well
* Graph iteration callbacks now receive the handle of the graph being iterated
* Indention is now more flexible because now it is not string but an integer
This introduces no new functionality but changes the way new apps are started.
Previously new app request were not queued, they were synchronous.
Now they are queued and asynchronous.
