The flag means that the process function might not complete
synchronously.
We can use this knowledge to improve the adapter. In sync mode we
can pull before scheduling the converter. In async mode we need to
schedule the follower after the converter to get the data ready for
the next iteration.
We can also improve the stream when it is operating async to schedule
a process call when a new buffer is ready to be filled.
This reduces a cycle latency from alsa and improves latency in
pulse.
Only try to reuse a buffer when the io area is not already in
the NEED_DATA state or else we might overwrite a previous buffer
reuse and run out of buffers.
We also always need more input.
For now, let's lower our priority in device reservation below that of
PulseAudio (which currently uses a priority of 0), so that it takes
priority while contending for the same device.
Make sure the default node as the highest priority.
Fixes a problem with default nodes not being selected when their
priority happens to be too low (bluetooth devices)
A passive node can still be the fallback node. It becomes non-passive
if there is a node assigned to it.
This makes the Dummy node work again in the case of jack clients
that always need to be scheduled.
When we destroy the proxy we should either take the thread lock
or stop the thread loop because the destroy might trigger a reply
to remove the object from another thread. This can cause the
refcounting to become invalid and cause double free.

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.
