Overview of changes from GLib 2.29.14 to 2.29.16
================================================

* GTlsDatabase: an abstract class that provides support
  or certificate and key lookup. An implementation will
  be provided in glib-networking

* GHmac: Support or HMAC digests

* Misc new API:
 - g_ptr_array_add_full: creates a GPtrArray with
   a preallocated size and a destroy function
 - g_desktop_app_info_get_show_in: checks if a GDesktopAppInfo
   should be shown in a given desktop environment
 - g_mkdtemp, g_mkdtemp_full, g_dir_make_tmp: create
   temporary directories

* Unify thread wakeup implementations of GMainContext
  and GCancellable, and use eventfd for it when available

* Show mounts in $XDG_USER_DIR in addition to /media and $HOME

* Bugs fixed:
