This is just taking the existing serialization code and repackaging it in a
more useful form.

bitcoin/tx: use fromwire_fail in pull_bitcoin_tx.
This is the correct way to mark failure: it also sets *max to 0.

daemons: use amount_msat/amount_sat in all internal wire transfers.
As a side-effect of using amount_msat in gossipd/routing.c, we explicitly
handle overflows and don't need to pre-prune ridiculous-fee channels.

Remove tal_len, use tal_count() or tal_bytelen().
tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

common: new directory for any shared objects.
To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

struct secret: use everywhere.
We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

sphinx: Removing last vestiges of the end-to-end payload
So far this was simply set to a zero-length end-to-end payload. We

of the unused code.
