1) detect port changes
2) restore or save port changes
3) if port changes:
check and restore the best profile
else check and restore the best ports
4) if profile changed, check and restore best ports
See #533
See #708
When we have a rate or channels configured, set this in the hw_params
to restrict the enumeration of the remaining parameters. If we,
for example want 8 channels, some cards restrict the formats in that
case and we don't want to enumerate impossible combinations.

First check all the routes to see if anything changed. If there is
a change check if we need a profile switch.
Then check all the active routes and restore state when they changed.
Add save property to Profile and Route params to notify the session
manager that they should be saved. Let the session manager only save
the Profile and Routes with the save flag.
Make pulse-server set the save flag on Profile and Route changes.
The result is that we can make a difference between user requested
changes and automatical changes and only remember the user preferences.
When a port changes availability, first check if we need to perform
a profile switch, if not select the new best port.
There is no need to copy the properties, just pass ownership.
Make sure to always have properties for the server. Ensure we
clean up properties on error.
We can only handle PCM encodings for now, fail conversion otherwise.
If we have no supported formats, return an error code.
VLC first try to send AC3 or EAC3 passthrough and then tries again
with decoded data. If we accept the encoded data we are just playing
noise.

Use log.level from the config file if not otherwise set with
PIPEWIRE_DEBUG env.
Make client log.level = 0 by default to avoid spamming the console
with errors.

Ignore property updates for keys that we manage ourselves like the
object.id, node.id etc. Otherwise a client can replace this with
their local ids and cause confusion.
Keep track of the param changes with the user counter. Make sure to
flip the serial switch whenever a change is pending. Previously
we copied the param from the channelmixer or follower but that
did not always result in a serial change.
Fixes#764
Not all devices report their A2DP delay. In those cases, use a fallback
value of 150ms by default.
Make the delay adjustable with a SPA_Prop, and expose it as a part of
the route. Implement the corresponding parts in media-session.
