The motivation is to have both existing and new streams that have been
created without explicit target node, to be directed to the same devices
at all times. To achieve this:
Consider what find_node returns as the "default node".
Consider streams that auto+reconnect and don't have an explicit target,
as following default. In rescan, if the default node has changed,
relink such streams to the new default.
Remove the old code that explicitly moved streams when the default.*
metadata changed, as it implements a similar thing but in a less robust
way (may fail to do what's intended, because the default device
metadata is commonly unset, or the metadata callback comes before
session_create has seen the new nodes).
Enable this feature based on "policy-node.streams-follow-default"
property. Allow setting the property also by loading the
streams-follow-default module. Enable it by default only for the
with-pulseaudio module group.
Remove -e and -d options
Manage modules in media-session.conf
Add alsa-monitor.conf that can match node/device properties with
a regex and update properties on it. All previous configuration and
more cane be done with this.
Save settings as jason and use a small json compatible tokenizer to
load settings instead of our own less flexible format.
Save settings with a prefix and filter out entries without prefix
Listen for changes in restore.stream metadata and update properties.
Don't start the pulse-bridge automatically because we don't
know what socket to listen on.
Also, listen by default on a safe socket, not used by pulseaudio.
Remove the hooks we installed on objects in the destroy/free event
or before calling _destroy. This is not really needed but it is
a nice thing to do because it calls the hook removed callbacks.
A rescan can trigger a new rescan and with a blocking rountrip this
can recursively never end. Catch a rescan while rescanning and queue
it for when we end the current scan.

Always use a default set of options and have enable/disable
add/remove options to/from it. Previously to enable just one option
you had to list all the other default enabled options as well.
Keep a per node entry of the saved target node and use this when
there is no other target node.
When explicitly moving a stream, save the new target node.
Currently pipewire-media-session uses ~/.pipewire-media-session for
storing configuration. Use home directory as specified by XDG base
directory specification viz. XDG_CONFIG_HOME and fall back to using
a default of $HOME/.config as per the spec if XDG_CONFIG_HOME is not
set or empty. Also in addition, all cases are now handled the same
and always end up using "%s/.config/pipewire-media-session".
If neither XDG_CONFIG_HOME or HOME are set, fall back to the earlier
approach.
