The implementation of GValue is not public or documented. When
allocated on the stack, initializing a GValue is usually done as
documented with:
GValue value = { 0, };
There is lot code around (including WebKit) that added all the missing
fields, resulting in this ugly and non-obvious:
GValue value = { 0, { { 0 } } };
However, this doesn't play nice with -Wmissing-field-initializers for
example. Thus, G_VALUE_INIT.
