Double spending tx are considered replacement

[lontivero]

After this PR the unconfirmed double spending transactions are considered replacements. Latest seen transactions are considered replacements for those already known independently of the fees.

How will the coordinator react if I send a tx with the coin that was coming from the replacement tx. Or if I try to register the coin to the CJ?

The backend is the broadcating fallback mechanism, not the main one. It will accept or reject the transaction depending on how it is configured.
This PR contains something that needs to be done before we switch to Full-RBF.

I see, so this will break the fallback mechanism in some cases. It is not good.

How is it configured?

we switch to Full-RBF

Do we go for it? That project needs to be prepared and well considered when everything is ready, switch on both client and backend side. Otherwise the backend and client or vice versa won't be on the same page and we will have a lot of issues.

It would be good to have a meeting about this first.

ACK we agreed on the meeting this is a safe change.
