This is especially useful for protocols such as splicing; for simplified commitment transactions, there is already an implied initiator at each point, so having the negotiation at splicing time would be redundant. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
… channel. The initiator (in the case of simultaneity, the higher feepayer) pays for the input and output, and sets the feerate. We freeze the channel while this construction is going on: it should be quick.

Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Header from folded patch 'fixup2.patch': fixup! splice_locked: terminate this splice once one reaches agreed depths. Use 6; we need to start announcing then anyway, so keep it simple.
This was Matt Corallo's idea; a simple flag means you should keep using the channel as it's being replaced. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Header from folded patch 'fixup.patch': fixup! gossip: make sure to send new announcement_signatures post-splice. It's called `splice_locked` and it's always sent 6 blocks.

they don't like. For instance if a node has a policy of only accepting channels of a certain size and then their peer tries to lower it with splice.
