The protobuf 3.15.2 suffers from the C++ "Static Initialization Fiasco"
issue. This patches makes the extension attributes have a higher
priority than the attributes, so there's no possibility of random
initialization orders.

+Subject: Lower init prio for extension attributes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Added PROTOBUF_EXTENSION_ATTRIBUTE_INIT_PRIORITY in
+code generation for extension attributes.
+It has lower prio than PROTOBUF_ATTRIBUTE_INIT_PRIORITY to
+ensure that extension attributes are initialized after
+other attribute.
+This is needed in some applications to avoid segmentation fault.
+
+Reported by Karl-Herman Näslund.
