Add a port_info event. With this, we get updates to ports pushed to
us, which is more convenient and also allows for better dynamic
add/remove of ports.
We don't need to the PortChanged event anymore
We can remove the get_port_ids/get_n_ports/port_get_info methods.
Update plugins
meson < 0.46 does not allow two targets to share the same name;
meson >= 0.46 relaxes that requirement, but I see no reason to require
a new version of meson just for this
If these optional plugins are enabled in meson options,
then the dependencies should be required to proceed.
It is not cool to compile with let's say bluez5 explicitly
enabled and after compilation discover that bluez was not
found and meson silently skipped that plugin.
This allows finding dependencies conditionally, only
when the enabled features actually need them.
Also, make sure to require those dependencies when the enabled
features do need them, instead of using "required: false" and
failing later
Make an eventfd for each node and listen for events when the node
is activated.
Reorganize some graphs links to make it possible to activiate nodes
by signaling the eventfd
Pass the peer node to each remote node and let the remote node
directly activate the peer when needed.
Let each node signal the driver node when finished.
With this we don't need to go through the daemon to schedule the
graph, nodes will simply activate eachother. We only go to the
server when there is a server node to schedule.
Keep stats about the state of each node and the time it was
triggered, running and finished.
This will make it possible to select the right graph before we
start processing. The idea is that graph updates happen in a new
version and that the switch will to the new updated graph is done
when the period starts.
Improve the allocators to always align the buffer memory to the
requested alignment
Use aligned read and writes for sse functions and check alignment,
optionally falling back to unaligned path.
Add more tests and benchmark cases
Check and warn for misaligned memory in plugins.
Remove the spa_pod_iter helpers
Remove builder/parser vararg recurse option, you have to
manually recurse into structures when needed. This simplifies
things a lot.
Pass spa_pod_frames to builder and parser explicitly, we don't
have to keep an internal stack anymore.
The parser is now almost a mirror image of the builder.
Make the parser safer when iterating over objects, add functions
to check and get pod contents in a safe way.
Make the builder return errno style results on errors
Improve performance of object properties when they are stored and
retrieved in the same order.
Add many more tests for the builder and parser
Add some benchmarks
