+ common: Disable enum type stream operators for Qt >= 5.14
+
+ Starting from version 5.14, Qt provides stream operators for enum
+ types, which collide with the ones we ship in types.h. Disable
+ Quassel's stream operators when compiling against Qt 5.14 or later.
+
+ Add a unit test that ensures that enum serialization honors the width
+ of the underlying type.
