pipewire: handle deleting the capturer while a D-Bus call is in progress
If a D-Bus call is in progress when a BaseCapturerPipeWire is deleted, then
the user_data is invalid when the callback function is called. This results
in memory corruption.
To fix this, use a GCancellable. If it is canceled, the callback will be
called with a corresponding error. Detect this error and abort before
accessing the user_data.
Note: The first argument is the 'source_object'. For g_dbus_proxy_call()
this is the proxy object not the connection. This was not a problem before,
because it was not used.
