The "saved headset profile" is taken as the profile that was active when
the headset mode deactivates. So in case the user switches profile during
the time when the Communication input stream is active, the selected
profile is remembered next time.
* populate most session item properties from create-item.lua to keep
things more compact and readable
* use a standard naming scheme for the session item properties
* use session item properties instead of node properties in policy-node.lua
* improve policy-node's performance by converting the properties dictionary
less times for each session item
* refactor some policy logic and make things slighly more readable
* change the accepted values for 'context' in wp_si_linkable_get_ports();
use "input" and "output" to keep things clear, because the previous use
of NULL and "reverse" were implying that a node has only one "standard"
direction, but this is complicated for sinks w/ monitors and duplex nodes
* allow using monitors (which are Audio/Sink nodes in fact) as sources
* treat Audio/Duplex nodes as sinks, like p-m-s does
* respect the "stream.capture.sink" property of streams
Fixes#66
Make a module that creates a route-settings metadata and provides
some helper functions to parse the json fields.
Load the route-settings module in the policy.
Move the Notification settings to the metadata. Listen for metadata
updates and update our state table.
Fixes#51
After all, we can just load multiple lua config files/directories
from a single .conf file and so have both styles available for the
user to choose at runtime
