Rusty Russell 8b29062f78 BOLT 4: Simplify onion format. 
1. Only one per-hop thing, called `per-hop`, or `hops_data` when in aggregate.
2. Move HMAC to the end of stuff it covers, both of the packet itself, and the per-hop.
3. Use `channel-id` instead of RIPEMD(nodepubkey).
4. Use 4 byte amounts.
5. This is all for realm "0", we can have future realms.  We also have 16
   bytes of unused padding.
6. No longer need the `gamma` key, but document the `_um_` key used for
   errors.
7. Use normal 32-byte HMAC, not truncated 20-bytes, which more than eats
   up the room we saved.

The result is that the onion is now 1366 not 1254 bytes, but simpler.
