Since we are driving the screencast there are no events on the pipewire loop
calling the on_event callback. We want to import and export (if possible) on
every frame of the wlroots loop, so this event is no longer needed.
The default node_id is SPA_ID_INVALID.
We are casting pipewire uint32_t node_id to int for printing since they are
currently staying in the range of low integer numbers. This makes
spotting an uninitialized node_id (casted to -1) much easier. Should be
corrected if that becomes an issue in the future.
This makes xdpw exit when either the D-Bus daemon, the Wayland
compositor or Pipewire is shut down. This avoids having dangling
non-functional xdpw instances, e.g. when restarting the compositor.
To test, start Sway nested in Sway, run xdpw with
WAYLAND_DISPLAY=wayland-2, and exit the nested Sway.

Supports "dmenu" chooser type, which is called with a dmenu type list
piped to stdin, "simple" type, which recieves nothing on stdin and
default, which tries the hardcoded choosers.
Choosers are required to return the name of the choosen output as given
by the xdg-output protocol.
Thanks to piater for closing overlooked pipes.
Thanks to ericonr for suggestions regarding fork and pipes.
Make sure that in SPA_POD_CHOICE_ENUM_Id(n_vals, ...) we always pass
exactly n_vals arguments. For this we build the object with separate
spa_pod_builder_add calls, since n_vals is known at runtime.
Fix#102
According to the spec, ~/.config is a fallback used when
XDG_CONFIG_HOME is unset. When the user has explicitly set
XDG_CONFIG_HOME, we shouldn't try to use the fallback.
