63f22d70b5 gossip: Store channel deletions so we don't re-add them on restart 
If we only remember the actions that added channels then we'd restore them when
re-reading the gossip_store, so put a tombstone in there to remember to delete
it. These will be cleared upon re-writing the store since the announcements wont
be written anymore.

0a5ea76d77 gossip: Add message types to store gossip msgs and associate data 
Since we may want to extend the on-disk format by adding custom information we
may as well just go the extra mile and reuse the serialization primitives we
already have.

46cc7c281e features: more general accessor functions. 
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.

8c665835fa jsonrpc: make explicit call to indicate cmd is still pending. 
jsonrpc handlers usually directly call command_success or
command_fail; not doing that implies they're waiting for something
async.

Put an explicit call (currently a noop) there, and add debugging
checks to make sure it's used.
