Changes for flatpak:

  • Fix file descriptor leaks affecting Chromium-based browsers.
  • Fix installing extra-data without a runtime, including OpenH264.
  • Ignore unusable sandbox-expose paths for portal sub-sandboxes, fixing Epiphany regressions.
  • Fix installed tests and handling of standard file descriptors passed as invalid flatpak run arguments.
  • Switch from Autotools to Meson, preserving system bubblewrap, xdg-dbus-proxy, curl and distribution-specific installation paths.
  • Require bubblewrap >= 0.10.0 and GPGME >= 1.8.0; add Meson, gettext, gtk-doc and polkit-agent build dependencies and drop obsolete intltool and libelf build dependencies.
  • Generate the system-user pre-script from the Meson build directory and package the tmpfiles configuration and renamed manual pages.
