Overview of changes from GLib 2.38.1 to 2.38.2
===============================================

* GCancellableSource will now dispatch for each time a cancellable is
  cancelled (ie: in the case that it was reset) but this is still
  considered undefined behaviour

* fix g_source_add_child_source() thread safety issues

* add workaround for buggy D-Bus daemons when path-matching on '/'

* fallback to pathname queryinfo to help g_file_copy() work on gvfs
  filesystems that don't implement query_info_on_read()

* don't crash if loading a DBusActivatable application from keyfile

* fix crash when replacing a symlink with another using GIO

* add a fallback for '-symbolic' icons to the non-symbolic form
