Prefer G_IO_ERROR_CANCELLED inside the daemon
This MR deprecates the use of MM_CORE_ERROR_CANCELLED
inside the daemon in favor of G_IO_ERROR_CANCELLED
, and at the same time we re-register G_IO_ERROR_CANCELLED
as MM_CORE_ERROR_DBUS_PREFIX ".Cancelled"
so that we can emit it via DBus as a known error
