Ends the builder process and returns the constructed value.
It is not permissible to use builder in any way after this call
except for reference counting operations (in the case of a
heap-allocated GVariantBuilder) or by reinitialising it with
g_variant_builder_init() (in the case of stack-allocated).
It is an error to call this function in any way that would create an
inconsistent value to be constructed (ie: insufficient number of
items added to a container with a specific number of children
required). It is also an error to call this function if the builder
was created with an indefinite array or maybe type and no children
have been added; in this case it is impossible to infer the type of
the empty array.
