Announce: Flatpak 1.15.2 (development prerelease)

[Simon McVittie]

Available here: https://github.com/flatpak/flatpak/releases/tag/1.15.2

This is a development prerelease for the adventurous, part of the 1.15.x
branch, which will eventually lead to a 1.16.0 stable release. Don't
include this version in stable OS distributions.

Some of the bug fixes in this release will also be included in 1.14.2,
which I'm hoping to release soon.

Bug fixes:

* Never try to export a parent of reserved directories as a --filesystem,
  for example /run, which would prevent the app from starting (#5205, #5207)
* Never try to export a --filesystem below /run/flatpak or /run/host,
  which could similarly prevent the app from starting
* The above change also fixes apps not starting if a --filesystem is a
  symlink to the root directory (#1357)
* Show a warning when the --filesystem exists but cannot be shared with
  the sandbox (#1357, #5035, #5205, #5207)
* Display the intended messages for flatpak repair (#5204)
* Exporting an app to an existing repository on a CIFS filesystem
  now works as intended (#5257)
* Unset $GIO_EXTRA_MODULES for apps, avoiding misbehaviour in some GLib
  apps when set to a path on the host (#5206)
* Unset $XKB_CONFIG_ROOT for apps, avoiding crashes in GTK and Qt apps
  under Wayland when this variable is set to a path not available in the
  sandbox (#5194)
* When using the fish shell, avoid duplicate XDG_DATA_DIRS entries if the
  profile script is sourced more than once (#5198)
* Update included copy of bubblewrap to 0.7.0 for better error messages
* Install SELinux files correctly when building with Meson
* Translation updates: ru, tr (#5256, #5262)

Internal changes:

* Update included copy of libglnx
* flatpak -v now uses the INFO log level, and flatpak -vv uses the
  DEBUG log level in the flatpak log domain. Previously, the extra
  messages that were logged by flatpak -vv were in a separate "flatpak2"
  log domain. G_MESSAGES_DEBUG=flatpak previously had an effect similar to
  flatpak -v, and is now more similar to flatpak -vv. (#5001)
