Make a port.extra property that contains API specific extra port
information that is passed in the global object properties.
Use this to pass the custom jack flags for a port. Carla uses this
to mark CV ports.
Release the transport if it went idle, ensuring that the fd is closed,
and add safeguards we won't double-acquire/release it.
This can occur if the device pauses the playback. The transport may also
activate again later on, and in this case we need to reacquire a new fd.
Not closing the old fd causes problems in this case.
However, apparently the BlueZ Release() call fails if the transport is
idle. We just ignore the error and downgrade the error message; it might
not be safe to not call Release() because the idle property update is
async.
Make a2dp clock advance at the correct rate.
Revert back to accumulating to a single buffer before sending it out.
What it did previously seemed hard to get to work properly with e.g.
aptx which produces block of varying sizes on decoding.
Use separate metadata keys for the current effective default nodes
(default.*), and user-configured ones (default.configured.*).
default-nodes saves and restores the configured ones, and policy-node
keeps the effective ones up to date.
For pipewire users, the effective default values should be considered
read-only, as changing them will not have an effect. To avoid
confusion, policy-nodes will reset their values back immediately if they
are changed.
Implement monitor volumes in the merger. There are two volumes,
the channel volume and the monitor volume. The monitor volume
is always applied.
By default the monitor volume will now follow the main volume of
the node. This can be disabled with a monitor.channel-volumes
property.

When sending captured data to a client, pulseaudio limits the
size of the block to the fragsize. Let's do the same just in case
a client can't deal with more data.
See #615
Make it possible to add a NULL param to the pending list. The NULL
param removes all previous updates.
When applying the updates, the NULL param removes the params from
the target list.
For the cached params in the node/device/port we need to be careful
because multiple clients might ask for updates concurrently. Clear
the pending list whenever a new param update starts so that we always
only keep the last set of updates.
This has two advantages: it actually removes params that become
unreadable or that got removed and it allows us to update the target
list more efficiently in one single loop.
