Overview of changes in GLib 2.73.1

• Remove the -Diconv configure option, as GLib now uses Meson’s built-in logic for
  finding which iconv implementation to use (work by Eli Schwartz) (!2734)

• Move gvdb to a Meson subproject and git submodule to avoid duplicating its
  source (work by Philip Withnall) (!2733)

• Add add_test_setup() in Meson to allow GLib tests to be run under valgrind
  with correct settings easily, using meson test --setup=valgrind (work by
  Philip Withnall) (!2752)

• Fix deadlocks when disposing non-cancelled inotify GFileMonitors (work by
  Benjamin Berg) (#1941)

• Fix file:// requests in webkit2gtk due to incorrect xdgmime update (work by
  Stephen Jung, Michael Catanzaro, Philip Withnall) (#2639)

• Fix build errors on macOS ≤10.7 for LOCAL_PEERPID (work by Christopher Nielsen) (!2707)

• Add new g_atomic_int_exchange() and g_atomic_pointer_exchange() APIs (work
  by Marco Trevisan) (!2726)

• Add new GListStore:n-items property to allow easy binding in UIs (work by
  Benjamin Otte) (!2738)

• Performance improvements for GObject construction and destruction (work by
  Matthias Clasen) (#2661, #2665, #2666, !2678, !2700, !2705, !2712, !2713,
  !2714, !2715, !2716, !2721, !2722, !2723, !2724, !2725, !2756)

• Use a numeric space (U+2007) for padding with some g_date_time_format()
  placeholders (work by Maksym Hazevych) (#2655)

  (work by Jens Georg) (#2670)
