Overview of changes in GLib 2.79.0, 2023-12-22

• Port to gi-docgen and drop gtk-doc support — dependencies have changed, and
  Meson needs -Ddocumentation now rather than -Dgtk_doc (#3037, work by
  multiple people)

• Move libgirepository into glib.git from gobject-introspection.git — but tools
  like g-ir-scanner are currently still in gobject-introspection.git. For the
  moment, glib.git needs to be built twice, once with -Dintrospection=false,
  then build gobject-introspection.git, then re-build glib.git with
  -Dintrospection=true. This process will evolve throughout the GLib 2.80
  cycle. The API and ABI of libgirepository has changed, and accordingly its
  version number has been bumped from 1.0 to 2.0 (note: the version number of
  GIRepository-*.gir has been bumped from 2.0 to 3.0; see !3786). The GIR and
  typelib file formats have not been changed, and are still at version 1.0.
  (#3155, work by multiple people)

• Match behaviour for GAppInfo searches has changed (#3082, work by Nelson
  Benítez León)

• Rename GTK_USE_PORTAL environment variable to GIO_USE_PORTALS (#3107,
  work by Philip Withnall)

• Bump Meson dependency to 1.2.0 and depend on Python packaging module
  (!3666, !3752)
