takeVariant
Set the contents of a variant #GValue to @variant, and takes over the ownership of the caller's reference to @variant; the caller doesn't have to unref it any more (i.e. the reference count of the variant is not increased).
If @variant was floating then its floating reference is converted to a hard reference.
If you want the #GValue to hold its own reference to @variant, use g_value_set_variant() instead.
This is an internal function introduced mainly for C marshallers.
