So far this was simply set to a zero-length end-to-end payload. We
don't have any plans of re-adding it for the moment, so let's get rid
of the unused code.
Other than being neater (no more global list to edit!), this lets the
new daemon and old daemon have their own separate routines.

Allocate the route off the current command, not dstate. And in the
case where the route is somehow not via a peer, don't leak memory.

We need some way to reflect the tradeoff between the possible delay if
a payment gets stuck, and the fees charged by nodes. This adds a risk
factor which reflects the probability that a node goes down, and the
cost associated with losing access to our funds for a given time.

This is less convenient to use, but makes far more sense for a real
user (like a wallet). It can ask about the route, then decide whether
to use it or not.
This will make even more sense once we add a parameter to control how
long we let the HTLC be delayed for, so a client can query for high,
medium and low tolerances and compare results.

We stopped automatically retransmitting locally-generated add/removes
after a reconnect, but this breaks the "pay" interface as it stands.
The correct solution to this is to make the pay interface idempotent:
you can trigger it as many times as you want and it will only succeed
once.

It's not currently encrypted, but at least you get some idea now why
an HTLC failed. We (ab)use HTTP error codes for the moment.

We use libsecp256k1 to convert signatures to DER; we were creating a
temporary one, but we really should be handing the one we have in dstate
through. This does that, everywhere.

This is the command an actual user would use: it figures out the fee
and route, and pays it if it can.
