87a080d30e split code in htlc_switch: 
- raise OnionRoutingFailure whenever we want to fail a htlc
 - catch that exception in htlc_switch
 - this will avoid code duplication in the case of trampoline

e8a2fa5596 tests: lnpeer.htlc_switch: don't fulfill htlc until add is irrevocable 
This adds a failing test, where the HTLC switch fulfills an HTLC too soon,
before the corresponding 'update_add_htlc' is irrevocably committed.

6b90a2d36c lnpeer: implement upfront shutdown script logic 
Upfront shutdown script is a script provided on channel opening,
which will be used by the peer to enforce us closing to this script
on collaborative channel close.

4c70956687 filter callbacks to wallet: channel, payment_succeeded, payment_failed 
It is ugly that the 'channel' callback takes a wallet I guess,
but with channel backups in one wallet, and active channels in another,
it was causing problems... (when open simultaneously)

6040e953a3 wallet: implement reserving addresses, and use it for LN SRK to_remote 
- Use change addresses (instead of receive) for the static_remotekey to_remote outputs,
  and reserve these to greatly reduce the chance of address-reuse
- Use change addresses (instead of receive) for LN channel sweep addresses.
  Note that these atm are not getting reserved.
