In this one, we always send my_current_per_commitment_point, though it's
ignored. And we have our official feature numbers.

Generalize things a bit so OPTIONAL_FEATURE() and COMPULSORY_FEATURE()
work with either odd or even features, then explicitly use OPTIONAL_FEATURE
in our internal feature array.

We currently generally assume the features we offer are fixed; this
makes the code clearer and handles where we offer features iff
EXPERIMENTAL_FEATURES=1

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.
