common should not include specific per-daemon files. Turns out this
caused a lot of indirect includes to be exposed.

They're currently called varint, but there's a proposal to call them all
bigsize. Allow both for now.

Node ids are pubkeys, but we only use them as pubkeys for routing and checking
gossip messages. So we're packing and unpacking them constantly, and wasting
some space and time.
This introduces a new type, explicitly the SEC1 compressed encoding
(33 bytes). We ensure its validity when we load from the db, or get it
from JSON. We still use 'struct pubkey' for peer messages, which checks
validity.

Basically we tell it that every field ending in '_msat' is a struct
amount_msat, and 'satoshis' is an amount_sat. The exceptions are
channel_update's fee_base_msat which is a u32, and
final_incorrect_htlc_amount's incoming_htlc_amt which is also a
'struct amount_msat'.

Well, it's generated by shachain, so technically it is a sha256, but
that's an internal detail. It's a secret.
