Return G_VARIANT_PARSE_ERROR_RECURSION from g_variant_parse() if a
typedecl is found within a text-form variant which would cause any part
of the variant to exceed the maximum allowed recursion/nesting depth.
This fixes an oversight when G_VARIANT_MAX_RECURSION_DEPTH was
implemented, which allowed typedecls to effectively multiply the size of
an array if g_variant_parse() was parsing a text-form variant without
a top-level concrete type specified.
