As we add more features, the current code is insufficient. 1. Keep an array of single feature bits, for easy switching on and off. 2. Create feature_offered() which checks for both compulsory and optional variants. 3. Invert requires_unsupported_features() and unsupported_features() which tend to be double-negative, all_supported_features() and features_supported(). 4. Move single feature definition from wire/peer_wire.h to common/features.h. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
