The code to check enumeration value policy can see special feature
flag 'deprecated' in QEnumLookup member flags[value]. I want to make
feature flag 'unstable' visible there as well, so I can add policy for
it.
Instead of extending flags[], replace it by @special_features (a
bitset of QapiSpecialFeature), because that's how special features get
passed around elsewhere.
