Instead of using GSimpleAsyncResult, use the new GTask API, which is
much more straightforward.
For using the new GTask API, let's bump GLib depency version to 2.36,
what is safe based on major distro support:
- Debian Jessie: glib-2.42
- RHEL-7.1: glib-2.40
- SLES12: glib-2.38
- Ubuntu LTS 14.04: glib-2.40
