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.
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.
We were checking both /etc/xdg-desktop-portal-wlr/ and
/etc/xdg/xdg-desktop-portal-wlr/. These two directories serve the same
purpose, let's just settle on a single one.
The goal is to control the rate of capture while in screencast, as it
can represent a performance issue and can cause input lag and the
feeling of having a laggy mouse.
This commit addresses the issue reported in #66.
The code measures the time elapsed to make a single screen capture, and
calculates how much to wait for the next capture to achieve the targeted
frame rate. To delay the capturing of the next frame, the code
introduces timers into the event loop based on the event loop in
https://github.com/emersion/mako
Added a command-line argument and an entry in the config file as well
for the max FPS. The default value is 0, meaning no rate control.
Added code to measure the average FPS every 5 seconds and print it with
DEBUG level.
This allows replacing a running xdpw instance. xdg-desktop-portal
itself has this feature.
This is useful when developing, to stop the currently running
system instance.
The error handling at the `error:` label tears down the whole state. Thus, the
state needs to be fully initialized in order for the tear down to succeed.
Currently, if e.g. `sd_bus_open_user()` fails, a `segfault` is triggered by
the tear down. This commit adds individual tear down code that only touches
stuff that until that point was successfully initialized.
* Initial session support WIP
Remove libdrm dependency
Remove display from context, add dbus properties
Use random names for shm and pw_stream, init the stream only for new cast instances
Separate cast initialized flag from refcount, cleanup names and comments
* Refactor and stability improvements
Properly report xdp screencast implementation version
