The Role traversal of config data to take notice of the
media class as well so that source and sink roles dont
overstep on each other and pick up unexpected endpoints.
This is expected to be printed if a stream opens and closes
very quickly, like in the case of pipewire-alsa opening the device
for querying formats and then closing it immediately.
If the default nodes module is loaded, and the default node is not found, it
means that there is no valid target for that session item. We only need to
manually find a default target if the default nodes module is not loaded.
This makes sure nodes are ready before finding the default node, avoiding audio
glitch in wrong device if profile was also changed while changing the default
node (can happen with Gnome Sound Settings).
Since nodes are destroyed and recreated again when a device profile changes, the
only way to make sure device nodes are ready is to check the profile classes
structure, which tell us how many total nodes the device has, and then check
that those nodes exist for that device. A rescan is triggered whenever devices,
nodes or ports changed.
This patch also improves the logic when finding default nodes, allowing virtual
sources to be set as default sources.

If a global is removed while an activation transition is in progress
and it happens that this activation transition was triggered by an
object manager, it is theoretically possible that this object manager
will then add this proxy after the transition completes, since
the transition is holding a ref on the proxy and therefore it will
not be destroyed. This ensures that the transitions are stopped on time
and the ref is dropped.
Because of this change, it is now also necessary to destroy the pw_proxy
on WpProxy's dispose() function, because if a proxy is removed before
it is bound, the registry aborts the activation but wp_proxy_deactivate()
is not destroying the proxy, since FEATURE_BOUND is not active.
In dispose() we can guarantee that the pw_proxy is destroyed.
meson devenv provides a convenient way of running the application
without installing it by overriding certain environment variables.
meson automatically overrides PATH and LD_LIBRARY_PATH, thus
there is no need to manually set those.
Running `meson devenv -C <builddir>` opens a new shell in the
build directory with the environment variables set up.
All core `pw_*_info` structures have a 64-bit change mask.
However, the `change_mask` in the session manager extension
info structures is only 32-bit. The differing sizes can cause
problems, especially on big endian architectures at the moment.
