Philip Withnall cc4de801c9 gobject: Reimplement g_param_values_cmp() for GParamSpecVariant 
The existing implementation was completely incorrect (despite the fix in
commit 566e64a66) — it always compared GVariants by pointer, rather than
by value.

Reimplement it to compare them by value where possible, depending on
their type. The core of this implementation is g_variant_compare(). See
the documentation and tests for further details of the new sort order.

This adds documentation and tests.
